SN54/74LS138

1-OF-8 DECODER/

DEMULTIPLEXER

The LSTTL/MSI SN54/74LS138 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 ex-

pansion 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 Motorola TTL families.

DEMULTIPLEXER

LOW POWER SCHOTTKY

• 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 Termination Effects
