54ACT138, 54AC138 Datasheet - National Semiconductor

54ACT138 1-of-8 Decoder/Demultiplexer

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/’.

54ACT138 Features

* n n n n n n n 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 Standard Microcircuit Drawing (SMD)

* ’AC138: 5962-87622

* ’ACT138: 5962-87554 Logic
