1-of-8 Decoder/Demultiplexer

General Description

The 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 ACT138 devices or a 1-of-32

decoder using four ACT138 devices and one inverter.

Note 1: Absolute maximum ratings are those values beyond which damage to the device may

occur. The databook specifications should be met, without exception, to ensure that

the system design is reliable over its power supply, temperature, and output/input

loading variables. National does not recommend operation of FACT TM circuits outside

databook specifications.
