SN74HCT138 Datasheet (Texas Instruments) - 3-Line to 8-Line Decoders/Demultiplexers

SN74HCT138, 3-Line to 8-Line Decoders/Demultiplexers

The ’HCT138 devices are designed for highperformance memory-decoding or data-routing applications requiring very short propagation delay times.

In high-performance memory systems, these decoders can minimize the effects of system decoding.

When employed with high-speed memories utilizing a fast ena
