SN74HC138PWR Description

Short technical summary and product information.

The SN74HC138PWR from Texas Instruments is a high-speed 3-line to 8-line decoder/demultiplexer designed for memory decoding and data transmission systems. It features a wide operating voltage range from 2V to 6V, making it versatile for various applications.

 

This device offers active low outputs and incorporates three enable inputs for simplified cascading or data reception. With a typical propagation delay of 15 ns, it is suitable for high-performance systems where minimizing decoding delay is crucial. The outputs can drive up to 10 LSTTL loads, and it has a low power consumption of 80 µA maximum ICC.

 

The SN74HC138PWR is available in a 16-TSSOP surface mount package. Its applications include LED displays, servers, white goods, power infrastructure, building automation, and factory automation. The device is designed to minimize system decoding effects in high-speed memory systems.

 

Key electrical characteristics include a supply current of 80 µA maximum and an output drive of ±4 mA at 5V. The low input current of 1 µA maximum further contributes to its efficiency.
