General Description
The AC/ACT138 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 AC/ACT138 devices or a 1-of-32 decoder using four AC/ACT138 devices and one inverter.
FEATUREs
■ ICC reduced by 50%
■ Demultiplexing capability
■ Multiple input enable for easy expansion
■ Active LOW mutually exclusive outputs
■ Outputs source/sink 24 mA
■ ACT138 has TTL-compatible inputs
