MC74HCT138A1-of-8 Decoder/ Demultiplexer with LSTTL Compatible InputsHigh−Performance Silicon−Gate CMOSThe MC74HCT138A is identical in pinout to the LS138. The HCT138A may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs.The HCT138A decodes a three−bit Address to one−of−eight active−lot outputs. This device features three Chip Select inputs, two active−low and one active−high to facilitate the demultiplexing, cascading, and chip−selecting functions. The demultiplexing function is accomplished by using the Address inputs to select the desired device output; one of the Chip Selects is used as a data input while the other Chip Selects are held in their active states.Features•Output Drive Capability: 10 LSTTL Loads•TTL/NMOS Compatible Input Levels•Outputs Directly Interface to CMOS, NMOS, and TTL •Operating V oltage Range: 4.5 to 5.5 V•Low Input Current: 1.0 m A•In Compliance with the Requirements Defined by JEDEC Standard No. 7A•Chip Complexity: 122 FETs or 30.5 Equivalent Gates•Pb−Free Packages are Available**For additional information on our Pb−Free strategy and soldering details, please download the ON Semiconductor Soldering and Mounting TechniquesReference Manual, SOLDERRM/D.MARKINGDIAGRAMSSOIC−16D SUFFIXCASE 751BTSSOP−16DT SUFFIXCASE 948FPDIP−16N SUFFIXCASE 648116MC74HCT138ANAWLYYWWG116HCT138AGAWLYWWA=Assembly LocationWL, L=Wafer LotYY, Y=YearWW, W=Work WeekG or G=Pb−Free Package(Note: Microdot may be in either location)See detailed ordering and shipping information in the package dimensions section on page 2 of this data sheet.ORDERING INFORMATIONHCT138AALYW GG116InputsOutputs CS1CS2CS3A2A1A0Y0Y1Y2Y3Y4Y5Y6Y7X X H X X X H H H H H H H H X HX X X X H H H H H H H H L X X X X X H H H H H H H H H L L L L L L H H H H H H H H L L L LH H L H H H H H H H L L L H L H HL H H H H H H L L L H H H H H L H H H H H L L H L L H H H H L H H H H L L H L H H H H H H LH H H L L H H L H H H H H H L H HLLHHHHHHHHHHLFUNCTION TABLEH = high level (steady state)L = low level (steady state)X = don’t careLOGIC DIAGRAMY6Y5Y4Y3Y2Y1Y0Y7CS1CS2ACTIVE-LOW OUTPUTSADDRESS INPUTSCS3CHIP-SELECT INPUTSCC PIN ASSIGNMENTA0CS2A2A1Y7CS1CS3GNDY3Y2Y1Y0V CC Y5Y4Y6Design Criteria Value Units Internal Gate Count*30.5ea.Internal Gate Propagation Delay 1.5nsInternal Gate Power Dissipation 5.0m W Speed Power Product.0075pJ*Equivalent to a two −input NAND gate.ORDERING INFORMATIONDevicePackage Shipping †MC74HCT138ANG PDIP −16(Pb −Free)500 Units / Box MC74HCT138ADG SOIC −16(Pb −Free)48 Units / Rail MC74HCT138ADR2G SOIC −16(Pb −Free)2500 Units / Tape & Reel MC74HCT138ADTR2TSSOP −16*2500 Units / Tape & Reel†For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D.*This package is inherently Pb −Free.MAXIMUM RATINGSSymbol Parameter Value Unit V CC DC Supply Voltage (Referenced to GND)– 0.5 to + 7.0V V in DC Input Voltage (Referenced to GND)– 0.5 to V CC + 0.5V V out DC Output Voltage (Referenced to GND)– 0.5 to V CC + 0.5VI in DC Input Current, per Pin±20mAI out DC Output Current, per Pin±25mAI CC DC Supply Current, V CC and GND Pins±50mAP D Power Dissipation in Still Air Plastic DIP†SOIC Package†TSSOP Package†750500450mWT stg Storage Temperature– 65 to + 150_C T L Lead Temperature, 1 mm from Case for 10 Seconds(Plastic DIP, TSSOP or SOIC Package)260_CStresses exceeding Maximum Ratings may damage the device.

MC74AC245, MC74ACT245Octal BidirectionalTransceiver with 3-State Inputs/OutputsThe MC74AC245/74ACT245 contains eight non−inverting bidirectional buffers with 3−state outputs and is intended for bus−oriented applications. Current sinking capability is 24 mA at both the A and B ports. The Transmit/Receive (T/R) input determines the direction of data flow through the bidirectional transceiver. Transmit (active−HIGH) enables data from A ports to B ports; Receive (active−LOW) enables data from B ports to A ports. The Output Enable input, when HIGH, disables both A and B ports by placing them in a High Z condition.Features•Noninverting Buffers •Bidirectional Data Path•A and B Outputs Source/Sink 24 mA •′ACT245 has TTL Compatible Inputs •These are Pb−Free DevicesPIN ASSIGNMENTPIN FUNCTION OE Output Enable Input T/R Transmit/Receive InputA 0−A 7Side A 3−State Inputs or 3−State OutputsB 0−B 7Side B 3−State Inputs or 3−State OutputsTRUTH TABLESInputs Outputs OE T/R L L Bus B Data to Bus A L H Bus A Data to Bus B HXHigh Z StateH = HIGH Voltage Level L = LOW Voltage Level X = ImmaterialFigure 1.V CC OE B 0B 1B 2B 3B 4B 5B 6B 7T/RA 0A 1A 2A 3A 4A 5A 6A 7GNDSOIC−20W DW SUFFIX CASE 751DTSSOP−20DT SUFFIX CASE 948E1See detailed ordering and shipping information in the package dimensions section on page 6 of this data sheet.ORDERING INFORMATIONSee general marking information in the device marking section on page 7 of this data sheet.DEVICE MARKING INFORMATIONMAXIMUM RATINGSSymbol Parameter Value Unit V CC DC Supply Voltage (Referenced to GND)−0.5 to +7.0V V IN DC Input Voltage (Referenced to GND)−0.5 to V CC +0.5V V OUT DC Output Voltage (Referenced to GND) (Note 1)−0.5 to V CC +0.5VI IK DC Input Diode Current±20mAI OK DC Output Diode Current±50mAI OUT DC Output Sink/Source Current±50mAI CC DC Supply Current, per Output Pin±50mA I GND DC Ground Current, per Output Pin±100mA T STG Storage Temperature Range*65 to )150_C T L Lead temperature, 1 mm from Case for 10 Seconds260_C T J Junction Temperature Under Bias140_Cq JA Thermal Resistance (Note 2)SOICTSSOP 65.8110.7_C/WMSL Moisture Sensitivity Level 1F R Flammability Rating Oxygen Index: 30% − 35%UL94V−*********V ESD ESD Withstand Voltage Human Body Model (Note 3)Machine Model (Note 4)Charged Device Model (Note 5)> 2000> 200> 1000VI Latchup Latchup Performance Above V CC and Below GND at 85_C (Note 6)±100mA Stresses exceeding those listed in the Maximum Ratings table may damage the device.

hc138 作用原理于高性能的存贮译码或要求传输延迟时间短的数据传输系统,在高性能存贮器系统中,用这种译码器可以提高译码系统的效率。

将快速赋能电路用于高速存贮器时,译码器的延迟时间和存贮器的赋能时间通常小于存贮器的典型存取时间,这就是说由肖特基钳位的系统译码器所引起的有效系统延迟可以忽略不计。

HC138 按照三位二进制输入码和赋能输入条件,从8 个输出端中译出一个低电平输出。

两个低电平有效的赋能输入端和一个高电平有效的赋能输入端减少了扩展所需要的外接门或倒相器,扩展成24 线译码器不需外接门;扩展成32 线译码器,只需要接一个外接倒相器。

在解调器应用中,赋能输入端可用作数据输入端。

The device has two independent decoders, each of which accepts two binary weighted inputs (A 0–A 1) and provides four mutually exclusive active–LOW outputs (O 0–O 3). Each decoder has an active–LOW enable (E). When E is HIGH all outputs are forced HIGH. The enable can be used as the data input for a 4–output demultiplexer application. Each half of the MC74AC139/74ACT139 generates all four minterms of two variables. These four minterms are useful in some applications, replacing multiple gate functions as shown in Figure 4, and thereby reducing the number of packages required in a logic network.E A 0A 1E A 0A 1E A 0A 1E A 0A 1O 0O 1O 2O 3Figure 4.

74HC138

74HC138中文资料74HC138 概述74HC138是一款高速CMOS 器件,74HC138引脚兼容低功耗肖特基TTL (LSTTL )系列。

74HC138译码器可接受3位二进制加权地址输入(A0, A1和A3),并当使能时,提供8个互斥的低有效输出(Y0至Y7)。

74HC138特有3个使能输入端:两个低有效(E1和E2)和一个高有效(E3)。

除非E1和E2置低且E3置高,否则74HC138将保持所有输出为高。

利用这种复合使能特性,仅需4片74HC138芯片和1个反相器,即可轻松实现并行扩展,组合成为一个1-32(5线到32线)译码器。

任选一个低有效使能输入端作为数据输入,而把其余的使能输入端作为选通端,则74HC138亦可充当一个8输出多路分配器,未使用的使能输入端必须保持绑定在各自合适的高有效或低有效状态。

74HC138与74HC238逻辑功能一致,只不过74HC138为反相输出。

74HC138功能:CD74HC138 ,CD74HC238和CD74HCT138 , CD74HCT238是高速硅栅CMOS 解码器,适合内存地址解码或数据路由应用。

74HC138 作用原理于高性能的存贮译码或要求传输延迟时间短的数据传输系统,在 高性能存贮器系统中,用这种译码器可以提高译码系统的效率。

将快速赋能电路用于高速存贮器时,译码器的延迟时间和存贮器的赋能时间通常小于存贮器的典型存取时间,这就是说由肖特基钳位的系统译码器所引起的有效系统延迟可以忽略不计。

MC74AC138 MC74ACT138
FUNCTIONAL DESCRIPTION
The MC74AC138/74ACT138 high-speed 1-of-8 decoder/ demultiplexer accepts three binary weighted inputs (A0, A 1, A2) and, when enabled, provides eight mutually exclusive active-LOW outputs (O0–O7). The MC74AC138/74ACT138 features three Enable inputs, two active-LOW (E1, E2) and one active-HIGH (E3). All outputs will be HIGH unless E1 and E2 are LOW and E3 is HIGH. This multiple enabled function allows easy parallel expansion of the device to a 1-of-32 (5 lines to 32 lines) decoder with just four MC74AC138/ 74ACT138 devices and one inverter (See Figure a). The MC74AC138/74ACT138 can be used as an 8-output demultiplexer by using one of the active LOW Enable inputs as the data input and the other Enable inputs as strobes. The Enable inputs which are not used must be permanently tied to their appropriate active-HIGH or active-LOW state.
* Maximum Ratings are those values beyond which damage to the device may occur. Functional operation should be restricted to the Recommended Operating Conditions.
