JM38510/33902BFA

Overview

The JM38510/33902BFA is a military-grade dual 4-line to 1-line data selector/multiplexer manufactured by Texas Instruments. It operates within the full military temperature range of -55 °C to 125 °C and utilizes a Ceramic Flat Package (CFP) with 16 pins. The device features two independent multiplexer sections sharing common select inputs A and B, each equipped with a separate strobe (enable) input for cascading capabilities. Electrical characteristics include a supply voltage range of 4.5 V to 5.5 V, low-level output current of 20 mA, and high-level output current of -1 mA.

Feature Summary

• Provides dual independent 4-to-1 data selection functionality with shared binary decoding logic
• Includes dedicated strobe inputs for each section to facilitate parallel-to-serial conversion and N-to-N line cascading
• Engineered for reliable operation across the complete military temperature spectrum

Applications

• Multiplexing multiple signal lines into a single transmission path
• Parallel-to-serial data conversion in communication systems
• Cascaded data routing configurations requiring independent section control

Procurement Notes

Verify that the component matches the specific military specification requirements for your application environment. Confirm the ceramic flat package integrity and pin configuration align with your PCB footprint design. Ensure that the supply voltage remains strictly within the 4.5 V to 5.5 V operational limits to maintain performance standards. Check for any specific handling instructions related to the ceramic packaging material.

Selection Notes

Select this component when dual independent multiplexing channels are required within a single package. It is suitable for applications demanding operation across extreme temperature variations found in military and defense sectors. Consider the CFP package dimensions and thermal properties during board layout planning. Verify compatibility with existing logic families regarding voltage levels and drive strength requirements.
