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

■ High Speed: tPD = 5.7ns (typ) at TA = 25°C

■ Low power dissipation: ICC = 4 µA (max.) at TA = 25°C

■ High noise immunity: VNIH = VNIL = 28 VCC (min.)

■ Power down protection provided on all inputs

■ Pin and function compatible with 74HC138
