SN74HC138DBR Description

Short technical summary and product information.

The SN74HC138DBR from Texas Instruments is a 3-line to 8-line decoder/demultiplexer designed for high-performance memory decoding and data routing. It features a wide operating voltage range from 2V to 6V, making it versatile for various system designs.

 

Key electrical characteristics include a typical propagation delay of 15ns and low power consumption with a maximum ICC of 80µA. The outputs can drive up to 10 LSTTL loads, and it offers ±4mA output drive at 5V. The device has active low outputs and incorporates three enable inputs for simplified cascading or data reception.

 

This decoder/demultiplexer is suitable for applications such as LED displays, servers, and factory automation. It is available in a 16-SSOP surface-mount package, measuring 0.209 inches (5.30mm) in width.

 

The SN74HC138 devices are designed to minimize system decoding delays in high-speed memory systems, ensuring negligible impact on overall system performance when used with fast enable circuits.
