The MC74VHC157 is an advanced high-speed CMOS quad 2-channel multiplexer, fabricated with silicon gate CMOS technology. It achieves high-speed operation similar to equivalent Bipolar-Schottky TTL, while maintaining CMOS low-power dissipation.

? High Speed: tPD = 4.1 ns (Typ) at VCC = 5 V

? Low Power Dissipation: ICC = 4 μA (Max) at TA = 25°C

? High Noise Immunity: VNIH = VNIL = 28 VCC

? Power Down Protection Provided on Inputs

? Balanced Propagation Delays

? Designed for 2 V to 5.5 V Operating Range

? Low Noise: VOLP = 0.8 V (Max)

? Pin and Function Compatible with Other Standard Logic Families

? Latchup Performance Exceeds 300 mA

? ESD Performance: HBM > 2000 V; Machine Model > 200 V

? Chip Complexity: 82 FETs
