SN74AHC138DBR Description

Short technical summary and product information.

The SN74AHC138DBR from Texas Instruments is a high-performance 3-line to 8-line decoder/demultiplexer. Designed for applications requiring very short propagation delay times, it is particularly suited for high-speed memory decoding and data-routing systems.

 

This device operates over a wide voltage range of 2V to 5.5V. It features three enable inputs that simplify cascading and data reception. The SN74AHC138DBR is available in a 16-SSOP surface-mount package.

 

Key electrical characteristics include a maximum supply current of 40µA and an operating temperature range of -40°C to 85°C. ESD protection is rated at 2000V for the Human-Body Model and 1000V for the Charged-Device Model. Latch-up performance exceeds 250mA per JESD 17.
