decoder/demultiplexer. This device is ideally suited for high−speed
bipolar memory chip select address decoding.
The multiple input enables allow parallel expansion to a 1−of−24
decoder using just three MC74AC138/74ACT138 devices or a
1−of−32 decoder using four MC74AC138/74ACT138 devices and one
inverter.
