General Description
   The VHC157 is an advanced high speed CMOS Quad 2-Channel Multiplexer fabricated with silicon gate CMOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.

FEATUREs
◾ High Speed: tPD = 4.1ns (Typ.) at VCC = 5V
◾ Low power dissipation: ICC = 4µA (Max.) at TA = 25°C
◾ High noise immunity: VNIH = VNIL = 28% VCC (Min.)
◾ Power down protection is provided on all inputs
◾ Low noise: VOLP = 0.8V (Max.)
◾ Pin and function compatible with 74HC157
