Product Summary

The SN74LS138NSR 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, the SN74LS138NSR can be used to minimize the effects of system decoding. The device is characterized for operation over the full military temperature range of 0℃ to 70℃.

Parametrics

SN74LS138NSR 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

SN74LS138NSR 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.
