M38510/33902BFA

Overview

The M38510/33902BFA is a military-grade dual 4-line to 1-line data selector/multiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating free-air temperature range from -55 °C to 125 °C. The device features two independent multiplexing sections with common select inputs A and B, allowing for parallel-to-serial conversion or N-to-one line multiplexing. Each section includes a separate strobe (enable) input for cascading applications. The component is housed in a 16-pin Ceramic Flat Package (CFP).

Feature Summary

• Contains inverters and drivers to provide full binary decoding for data selection.
• Features separate strobe inputs for each of the two 4-line sections.
• Supports cascading capabilities for N lines to N lines configurations.

Applications

• Multiplexing from N lines to one line
• Parallel-to-serial data conversion
• Military and defense electronic systems

Procurement Notes

Verify that the procurement source provides documentation confirming QML certification under MIL-M-38510 Class B standards. Ensure the delivered components match the specified CFP package type and pin configuration. Confirm compliance with the required military temperature range specifications during acquisition.

Selection Notes

Select this component when designing systems requiring high-reliability logic functions in extreme environmental conditions. It serves as a suitable replacement for standard commercial logic devices in applications demanding extended temperature tolerance and radiation-hardened performance characteristics.

Part Context

This part belongs to the SN54F153 series, representing the military-grade variant of the F-series logic family. It is distinct from the commercial SN74F153 due to its wider operating temperature range and specific packaging options designed for rugged environments.

Replacement Considerations

Direct equivalents include JM38510/33902BFA and SNJ54F153W. Verify pin compatibility and electrical characteristics before substituting other multiplexer variants.

FAQ

What is the function of the G inputs?

The G inputs serve as strobe (enable) lines for each of the two 4-line sections, controlling data output based on the select inputs.

How are the select inputs configured?

Select inputs A and B are common to both multiplexing sections within the device.
