Overview

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.
• Demultiplexing Capability • Multiple Input Enable for Easy Expansion • Typical Power Dissipation of 32 mW • Active Low Mutually Exclusive Outputs • Input Clamp Diodes Limit High Speed ...
