74VHCT238A - 3 TO 8 LINE DECODER

General Description

The 74VHCT238A is an advanced high-speed CMOS 3 TO 8 LINE DECODER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.

If the device is enabled, 3 binary select inputs (A, B and C) determine which one of the outputs will go high.
