SN74LVC138A Description

Short technical summary and product information.

The SN74LVC138A from Texas Instruments is a 3-line to 8-line decoder/demultiplexer. It is designed for 2.7-V to 3.6-V VCC operation and is suitable for high-performance memory-decoding or data-routing applications requiring very short propagation delay times.

 

Key electrical characteristics include an operating voltage range of 2V to 3.6V, with inputs that can accept voltages up to 5.5V. The maximum propagation delay is 5.8 ns at 3.3V. It also features ESD protection exceeding 2000V per MIL-STD-883, Method 3015.

 

This device minimizes the effects of system decoding in high-performance memory systems. It has two active-low enable inputs and one active-high enable input, reducing the need for external gates or inverters when expanding decoder capabilities. An enable input can also serve as a data input for demultiplexing applications.

 

The SN74LVC138A is available in D (SOIC) and PW (TSSOP) packages, both surface mountable. It operates within a military temperature range of -55°C to 125°C and is part of Texas Instruments' Enhanced Product line, supporting defense, aerospace, and medical applications with controlled baselines and extended product life cycles.
