MICROCIRCUIT DATA SHEET Original Creation Date: 07/02/96 Last Update Date: 03/17/97 Last Major Revision Date: 07/02/96 MN54ACT138-X REV 1B0 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.

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.
