SN74LS138

1-of-8 Decoder/

Demultiplexer

The LSTTL/MSI SN74LS138 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 LS138

devices or to a 1-of-32 decoder using four LS138s and one inverter.

The LS138 is fabricated with the Schottky barrier diode process for

high speed and is completely compatible with all ON Semiconductor

TTL families.
