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.

Initial release: MNDM54LS138-X Rev. 1A0. Added note 4
to the AC (50pF) notes reference column. Reworded the
phrase in note 4 from "and periodically at +125C &
-55C, subgroups 10 & 11" to "Sugroups 10 & 11 are
guaranteed, not tested".
