74VHCT138A, 3 TO 8 LINE DECODER INVERTING

The 74VHCT138A is an advanced high-speed CMOS 3 TO 8 LINE DECODER (INVERTING) 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 low.

If enable input G1 is he
