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
● Standard Microcircuit Drawing (SMD)
❍ 'AC138: 5962-87622
❍ 'ACT138: 5962-87554
