General Description
The VHC138 is an advanced high speed CMOS 3-to-8 decoder/demultiplexer 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
â High Speed: tPD = 5.7ns (typ) at TA = 25°C
â Low power dissipation: ICC = 4 µA (max.) at TA = 25°C
â High noise immunity: VNIH = VNIL = 28% VCC (min.)
â Power down protection provided on all inputs
â Pin and function compatible with 74HC138
