Decoder/Demultiplexer
The MC74AC138/74ACT138 is a high
speed 1
of
8
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.
Demultiplexing Capability
Multiple Input Enable for Easy Expansion
Active LOW Mutually Exclusive Outputs
Outputs Source/Sink 24 mA
′
ACT138 Has TTL Compatible Inputs
