MICROCIRCUIT DATA SHEET Original Creation Date: 04/27/98 Last Update Date: 06/17/98 Last Major Revision Date: 04/27/98 MNDM54LS138-X REV 1A0 1 - of - 8 DECODER/DEMULTIPLEXERS General Description The LS138 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 '138 devices or to a 1of - 32 decoder using four '138 devices and one inverter. The '138 is fabricated with the Schottky barrier diode process for high speed.
