SN54HC138J Description

Short technical summary and product information.

The SN54HC138J from Texas Instruments is a 3-Line to 8-Line Decoder/Demultiplexer designed for high-speed memory decoding and data-transmission systems. It belongs to the HC technology family and offers a wide operating voltage range from 2V to 6V.

 

Key electrical characteristics include a maximum supply current of 160 µA and a low input current of 1 µA maximum. The device features a typical propagation delay of 15 ns and outputs capable of driving up to 10 LSTTL loads. It incorporates three enable inputs for simplified cascading or data reception, with active low outputs for selected outputs.

 

This decoder is targeted for applications requiring short propagation delays, making the system decoding delay negligible when used with high-speed memories. It is available in multiple package options including LCCC (FK), CDIP (J), and CFP (W).

 

The operating temperature range for this military-rated component is -55°C to 125°C.
