1-of-8 Decoder/Demultiplexer
General Description
The AC/ACT138 is a high-speed 1-of-8 decoder/demulti-
plexer. 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 AC/ACT138 devices or a 1-of-32 decoder
using four AC/ACT138 devices and one inverter.
