Motorola, Inc. 1997
High Speed: t PD = 5.1ns (Typ) at V CC = 3.3V
Low Power Dissipation: I CC = 4 A (Max) at T A = 25 C
Power Down Protection Provided on Inputs
Balanced Propagation Delays
Low Noise: V OLP = 0.5V (Max)
Pin and Function Compatible with Other Standard Logic Families
Latchup Performance Exceeds 300mA
ESD Performance: HBM > 2000V; Machine Model > 200V
The MC74LVX157 is an advanced high speed CMOS quad 2–channel
It consists of four 2–input digital multiplexers with common select (S)
The select decoding determines whether the I0n or I1n inputs get
