74HC138中文资料
74HC138中文资料74H C138是一款高速C MOS器件，74H C138引脚兼容低功耗肖特基TTL（LS TTL）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）。
74H C138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74H C138将保持所有输出为高。
利用这种复合使能特性，仅需4片74H C138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74H C138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。
74H C138与74H C238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。
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。

When enable input G1 is held "Low" or either G2A or G2B is held "High" decoding function isinhibited and all the 8 outputs go low. Three enable inputs are provided to ease cascade connection and application of this address decoder in memory systems.All inputs are equipped with protection circuits against static discharge and transient excess voltage.M74HC2383 TO 8 LINE DECODERPIN CONNECTION AND IEC LOGIC SYMBOLSORDER CODESPACKAGE TUBE T & RDIP M74HC238B1R SOP M74HC238M1RM74HC238RM13TR TSSOPM74HC238TTRM74HC2382/10INPUT AND OUTPUT EQUIVALENT CIRCUITPIN DESCRIPTIONTRUTH TABLEX : Don’t CareLOGIC DIAGRAMPIN No SYMBOL NAME AND FUNCTION 1, 2, 3A, B, C Data Inputs4, 5 G2A G2B Enable Input (Active LOW)6G1Data Enable Input (Active HIGH)15, 14, 13, 12, 11, 10, 9,7Y0 to Y7Outputs8GND Ground (0V)16V CCPositive Supply VoltageINPUTSOUTPUTS SELECTED OUTPUTENABLE SELECTG2B G2A G1C B A Y0Y1Y2Y3Y4Y5Y6Y7X X L X X X L L L L L L L L NONE X H X X X X L L L L L L L L NONE H X X X X X L L L L L L L L NONE L L H L L L H L L L L L L L Y0L L H L L H L H L L L L L L Y1L L H L H L L L H L L L L L Y2L L H L H H L L L H L L L L Y3L L H H L L L L L L H L L L Y4L L H H L H L L L L L H L L Y5L L H H H L L L L L L L H L Y6LLHHHHLLLLLLLHY7M74HC2383/10ABSOLUTE MAXIMUM RATINGSAbsolute Maximum Ratings are those values beyond which damage to the device may occur.

They are specified in compliance with JEDEC standard no. 7A.The 74HC/HCT238 decoders accept three binaryweighted address inputs (A 0, A 1, A 2) and when enabled,provide 8 mutually exclusive active HIGH outputs (Y 0 to Y 7).The “238” features three enable inputs: two active LOW (E 1 and E 2) and one active HIGH (E 3). Every output will be LOW unless E 1 and E 2 are LOW and E 3 is HIGH.This multiple enable function allows easy parallelexpansion of the “238” to a 1-of-32 (5 lines to 32 lines)decoder with just four “238” ICs and one inverter.The “238” can be used as an eight output demultiplexer by using one of the active LOW enable inputs as the data input and the remaining enable inputs as strobes. Unused enable inputs must be permanently tied to their appropriate active HIGH or LOW state.The “238” is identical to the “138” but has non-inverting outputs.QUICK REFERENCE DATAGND =0 V; T amb =25°C; t r =t f =6 ns Notes1.C PD is used to determine the dynamic power dissipation (P D in µW):P D =C PD × V CC 2× f i + ∑ (C L × V CC 2 ×f o ) where:f i =input frequency in MHz f o =output frequency in MHz ∑ (C L × V CC 2× f o )=sum of outputs C L =output load capacitance in pF V CC =supply voltage in V2.For HC the condition is V I =GND to V CCFor HCT the condition is V I =GND to V CC − 1.5 V ORDERING INFORMATIONSee “74HC/HCT/HCU/HCMOS Logic Package Information”.SYMBOL PARAMETER CONDITIONS TYPICAL UNITHCHCT t PHL/ t PLHpropagation delay C L =15 pF; V CC =5 VA n to Y n 1418ns E 3 to Y n 1620ns E n to Y n1721ns C I input capacitance3.5 3.5pF C PD power dissipation capacitance per packagenotes 1and 27276pFPIN DESCRIPTION PIN NO.SYMBOL NAME AND FUNCTION 1, 2, 3A 0 to A 2address inputs4, 5E 1,E 2enable inputs (active LOW)6E 3enable input (active HIGH)8GND ground (0 V)15, 14, 13, 12, 11, 10, 9, 7Y 0 to Y 7outputs (active HIGH)16V CCpositive supply voltageFig.1 Pin configuration.Fig.2 Logic symbol.Fig.3 IEC logic symbol.(a)(b)Fig.4 Functional diagram.Fig.5 Logic diagram.FUNCTION TABLENote1.H = HIGH voltage levelL = LOW voltage level X = don’t careINPUTSOUTPUTS E 1E 2E 3A 0A 1A 2Y 0Y 1Y 2Y 3Y 4Y 5Y 6Y 7H X X X H X X X L X X X X X X X X X L L L L L L L L L L L L L L L L L L L L L L L L L L L L L L L L H H H H L H L H L L H H L L L L H L L L L H L L L L H L L L L H L L L L L L L L L L L L L L L L L L L L L L L L H H H H L H L H L L H H H H H H L L L L L L L L L L L L L L L LH L L L L H L L L L H L L L L HDC CHARACTERISTICS FOR 74HCFor the DC characteristics see“74HC/HCT/HCU/HCMOS Logic Family Specifications”.

74HC238; 74HCT2383-to-8 line decoder/demultiplexerRev. 5 — 13 June 2018Product data sheet1General descriptionThe 74HC238; 74HCT238 decodes three binary weighted address inputs (A0, A1 andA2) to eight mutually exclusive outputs (Y0 to Y7). The device features three enableinputs (E1 and E2 and E3). Every output will be LOW unless E1 and E2 are LOW andE3 is HIGH. This multiple enable function allows easy parallel expansion to a 1-of-32(5 to 32 lines) decoder with just four '238 ICs and one inverter. The '238 can be usedas an eight output demultiplexer by using one of the active LOW enable inputs as thedata input and the remaining enable inputs as strobes. Inputs include clamp diodes. Thisenables the use of current limiting resistors to interface inputs to voltages in excess ofV CC.2Features and benefits•Demultiplexing capability•Multiple input enable for easy expansion•Ideal for memory chip select decoding•Active HIGH mutually exclusive outputs•Multiple package options•Complies with JEDEC standard no. 7A•Input levels:–For 74HC238: CMOS level–For 74HCT238: TTL level•ESD protection:–HBM JESD22-A114F exceeds 2000 V–MM JESD22-A115-A exceeds 200 V•Specified from -40 °C to +85 °C and from -40 °C to +125 °C3Ordering information3-to-8 line decoder/demultiplexer4Functional diagram001aag7523 TO 8 DECODERENABLE EXITING A01A12A23E14E25E36Y015Y114Y213Y312Y411Y510Y69Y77Figure 1.

74HC138译码器可接受3位二进制加权地址输入（A0, A1和A2），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。
编辑本段功能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。
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。
