SN74AHCT138-EP Datasheet 3-LINE TO 8-LINE DECODERS/DEMULTIPLEXERS

Manufacturer: Texas Instruments

General Description

/ordering information The SN74AHCT138 3-line to 8-line decoder/demultiplexer is designed to be used in high-performance memory-decoding and data-routing applications that require very short propagation-delay times.

In high-performance memory systems, this decoder can be used to minimize the effects of system decoding.

When employed with high-speed memories utilizing a fast enable circuit, the delay times of this decoder and the enable time of the memory usually are less than the typical access time of the memory.

Overview

SN74AHCT138-EP 3-LINE TO 8-LINE DECODER/DEMULTIPLEXER D Controlled Baseline – One Assembly/Test Site, One Fabrication Site D Extended Temperature Performance of –55°C to 125°C D Enhanced Diminishing Manufacturing Sources (DMS) Support D Enhanced Product-Change Notification D Qualification Pedigree† D EPIC (Enhanced-Performance Implanted CMOS) Process D Inputs Are TTL-Voltage Compatible D Designed Specifically for High-Speed Memory Decoders and Data-Transmission Systems † Component qualification in accordance with JEDEC and industry standards to ensure reliable operation over an extended temperature range.

This includes, but is not limited to, Highly Accelerated Stress Test (HAST) or biased 85/85, temperature cycle, autoclave or unbiased HAST, electromigration, bond intermetallic life, and mold compound life.

Such qualification testing should not be viewed as justifying use of this component beyond specified performance and environmental limits.
