JM38510/33701BEA

Overview

The Texas Instruments JM38510/33701BEA is a military-grade SN54F138 3-line to 8-line decoder/demultiplexer. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55 °C to 125 °C. The device features three enable inputs (one active-high, two active-low) and eight active-low outputs. It utilizes a 16-pin ceramic dual in-line package (CDIP).

Feature Summary

• Designed for high-speed memory decoding and data routing applications requiring short propagation delays.
• Incorporates three enable inputs to simplify cascading and demultiplexing without external inverters.
• Characterized for full military temperature operation (-55 °C to 125 °C).

Applications

• High-performance memory systems
• Data transmission systems
• Demultiplexing applications

Procurement Notes

Verify the specific ordering suffix 'BEA' against the manufacturer's current Package Option Addendum to confirm the CDIP-16 package configuration. Ensure that the component meets QML certification requirements if intended for defense or aerospace procurement channels.

Selection Notes

Select this component when military-grade reliability and extended temperature tolerance are required. It serves as a direct replacement for standard commercial SN74F138 devices in environments where operational stability below 0 °C is necessary.

Part Context

This part number belongs to the SN54F138 family manufactured by Texas Instruments. It represents the military qualification variant of the F-series logic decoders, distinguished by its robust packaging and wide thermal operating range compared to commercial counterparts.
