SN74LS137D

Overview

The SN74LS137D is a 3-line to 8-line decoder/demultiplexer with address latches from the Texas Instruments LS logic family. It features a 16-pin SOIC package and operates within a supply voltage range of 4.75 V to 5.25 V. The device supports a maximum operating temperature of +70 °C and includes three address inputs, eight outputs, and an enable input.

Feature Summary

• Integrates address latching functionality for stable decoding operations
• Provides demultiplexing capabilities alongside standard decoding functions
• Utilizes low-power Schottky (LS) technology for efficient performance

Applications

• Memory address decoding systems
• Demultiplexing data streams in digital circuits
• Control signal routing applications

Procurement Notes

Verify the specific 'D' suffix indicates the SOIC surface-mount package configuration. Confirm that the component meets the required industrial temperature specifications for your application environment. Ensure compatibility with existing 5V logic levels before integration into the design.

Selection Notes

Select this component when both decoding and address latching are required in a single integrated circuit. Consider the LS series characteristics regarding speed and power consumption relative to other logic families. Evaluate the physical footprint requirements against available PCB space constraints.

Part Context
