Product Summary

The SN74LS138DR is a 3-line to 8-line decoder/demultiplexer. It is designed to be used in high-performance memory decoding or data-routing applications requiring very short propagation delay times. In high-performance memory systems, this decorder can be used to minimize the effects of system decoding.

Parametrics

SN74LS138DR absolute maxing ratings: (1)Supply voltage VCC: 7V; (2)Input voltage: 7V; (3)Operating free-air temperature range: 0℃ to 70℃; (4)Storage temperature range: -65℃ to 150℃.

Features

SN74LS138DR features: (1)Designed specifically for high-speed: memory decoders; data transmission systems; (2)3 enable inputs to simplify cascading and/or data reception; (3)Schottky-clamped for high performance.
