The 3-state outputs (nY) are controlled by the output enable input (nOE). A HIGH at nOE causes the outputs to assume a HIGH impedance OFF-state.The “125” is identical to the “126” but has active LOW enable inputs.QUICK REFERENCE DATAGND = 0 V; T amb = 25°C; t r = t f = 6 nsNotes1.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 =output load capacitance in pF V CC =supply voltage in V∑(C L ×V CC 2×f o )= sum of outputs2.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 PARAMETERCONDITIONS TYPICAL UNIT HCHCTt PHL / t PLH propagation delay nA to nY C L =15pF; V CC =5V912ns C I input capacitance3.5 3.5pF C PD power dissipation capacitance per buffernotes 1 and 22224pFPIN DESCRIPTIONPIN NO.SYMBOL NAME AND FUNCTION1, 4, 10, 131OE to 4OE outputs enable inputs (active LOW)2, 5, 9, 121A to 4A data inputs3, 6, 8, 111Y to 4Y data outputs7GND ground (0V)14V CC positive supply voltageFig.1 Pin configuration.Fig.2 Logic symbol.Fig.3 IEC logic symbol.(a)(b)Fig.4 Functional diagram.Fig.5 Logic diagram (one buffer).FUNCTION TABLENote1.H=HIGH voltage levelL=LOW voltage levelX=don’t careZ=high impedance OFF-state INPUTS OUTPUT nOE nA nYLLHLHXLHZDC CHARACTERISTICS FOR 74HCFor the DC characteristics see“74HC/HCT/HCU/HCMOS Logic Family Specifications”.

74VHC125 — Quad Buffer with 3-STATE OutputsFeatures■ High Speed: t PD = 3.8ns (Typ.) at V CC = 5V ■ Lower power dissipation: I CC = 4 µA (Max.) at T A = 25°C■ High noise immunity: V NIH = V NIL = 28% V CC (Min.) ■ Power down protection is provided on all inputs ■ Low noise: V OLP = 0.8V (Max.)■Pin and function compatible with 74HC125General DescriptionThe VHC125 contains four independent non-inverting buffers with 3-STATE outputs. It is an advanced high-speed CMOS device fabricated with silicon gate CMOS technology and achieves the high-speed operation simi-lar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.An input protection circuit insures that 0V to 7V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5V to 3V systems and two supply systems such as battery backup. This circuit prevents device destruction due to mismatched supply and input voltages.Ordering InformationDevice also available in Tape and Reel.

The output is disabled whenthe output-enable (OE) input is high. When OE is low, true data is passed from the A input to the Y output.To ensure the high-impedance state during power up or power down, OE should be tied to V CC through a pullupresistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.ORDERING INFORMATIONT A PACKAGE †ORDERABLE PART NUMBER TOP-SIDE MARKING ‡Reel of 3000SN74AHCT1G125DBVR SOT (SOT-23) − DBVReel of 250SN74AHCT1G125DBVT B25_°°Reel of 3000SN74AHCT1G125DCKR −40C to 85C SOT (SC-70) − DCKReel of 250SN74AHCT1G125DCKT BM_SOT (SOT-553) − DRL Reel of 4000SN74AHCT1G125DRLR BM_†Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines areavailable at /sc/package.‡The actual top-side marking has one additional character that designates the assembly/test site.FUNCTION TABLEINPUTSOUTPUT OEA Y LH H LL L H X Zlogic diagram (positive logic)A YOE124Copyright 2005, Texas Instruments IncorporatedPRODUCTION DATA information is current as of publication date.Please be aware that an important notice concerning availability, standard warranty, and use in critical applications ofTexas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.SN74AHCT1G125SINGLE BUS BUFFER GATEWITH 3ĆSTATE OUTPUTSCLS378L − AUGUST 1997 − REVISED JUNE 2005absolute maximum ratings over operating free-air temperature range (unless otherwise noted)†Supply voltage range, V CC−0.5 V to 7 V. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Input voltage range, V I (see Note 1) −0.5 V to 7 V. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Output voltage range, V O (see Note 1) −0.5 V to V CC+ 0.5 V. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Input clamp current, I IK(V I< 0) −20 mA. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Output clamp current, I OK(V O< 0 or V O > V CC) ±20 mA. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Continuous output current, I O(V O= 0 to V CC) ±25 mA. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Continuous current through V CC or GND ±50 mA. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Package thermal impedance, θJA (see Note 2):DBV package 206°C/W. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .DCK package 252°C/W. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .DRL package 142°C/W. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Storage temperature range, T stg −65°C to 150°C. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .†Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.

Application informationThe slow input rise and fall times cause additional power dissipation, this can becalculated using the following formula:P add=f i⨯(t r⨯∆I CC(AV)+t f⨯∆I CC(AV))⨯V CCWhere:P add=additional power dissipation (μW)f i=input frequency (MHz)t r=rise time (ns); 10% to 90%t f=fall time (ns); 90% to 10%∆I CC(AV)=average additional supply current (μA)∆I CC(AV) differs with positive or negative input transitions, as shown in Figure14 and Figure15.74HC1G14 and 74HCT1G14 used in relaxation oscillator circuit, see Figure16.

led显示屏模组常用IC的引脚说明

引脚说明符号引脚描述Q0…Q7 8位并行数据输出，其中Q0为第15脚GND 第8脚地Q7’ 第9脚串行数据输出MR 第10脚主复位（低电平）SHCP 第11脚移位寄存器时钟输入STCP 第12脚存储寄存器时钟输入OE 第13脚输出有效（低电平）DS 第14脚串行数据输入VCC 第16脚电源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。
