TC74VHC157F

The TC74VHC157F is advanced high speed CMOS QUAD 2 channel multiplexer fabricated with silicon gate C2MOS technology.It achieves the high speed operation similar to equivalent bipolar schottky TTL while mantaining the CMOS low power dissipation.This circuit prevents device destruction due to mismatched supply and input voltage.

Features of the TC74VHC157F are:(1)high speed:tpd=4.1ns(typ.) at Vcc=5V;(2)low power dissipation:ICC=4A(max) at Ta=25;(3)high noise immunity:VIH=VNIL=28%VCC(min);(4)power down protection is equipped with all inputs;(5)low noise is VOLP=0.8V(max);(6)wide operating voltage range:VCC(opr)=2 to 5.5V;(7)pin and function and compatible with 74ALS157;(8)balanced propagation delays is tpLH=tpHL.

The maximum ratings of the TC74VHC157F can be summarized as:(1):the characteristic is supply voltage range,the symbol is VCC,the rating is -0.5 to 7.0,the unit is V;(2):the characteristic is DC input voltage,the symbol is VIN,the rating is -0.5 to 7.0,the unit is V;(3):the characteristic is DC output voltage,the symbol is VOUT,the rating is -0.5 to VCC+0.5,the unit is V;(4):the characteristic is input diode current,the symbol is IIK,the rating is -20,the unit is mA;(5):the characteristic is output diode current,the symbol is IOK,the rating is ±20,the unit is mA;(6):the characteristic is DC output current,the symbol is IOUT,the rating is ±25,the unit is mA;(7):the characteristic is DC VCC/ground current,the symbol is ICC,the rating is ±50,the unit is mA;(8):the characteristic is power dissipation,the symbol is PD,the rating is 180,the unit is mW;(9):the characteristic is storage temperature,the symbol is Tstg,the rating is -65 to 150,the unit is .
