M38510/34101BCA

Overview

The M38510/34101BCA is a dual positive-edge-triggered D-type flip-flop manufactured by Texas Instruments under the SN54F series. It features two independent data storage elements with dedicated Clear and Preset inputs for direct control. The device utilizes TTL input logic and provides standard outputs. It is designed for military-grade reliability, operating within a temperature range of -55°C to +125°C. Power supply requirements are strictly defined between 4.5 V and 5.5 V. The component is housed in a 14-pin ceramic dual in-line package (CDIP) suitable for through-hole mounting.

Feature Summary

• Dual configuration containing two independent positive-edge-triggered D-type flip-flops
• Includes dedicated asynchronous Clear and Preset inputs for immediate state control
• Military-grade construction ensuring operation across extended temperature ranges
• TTL-compatible input logic levels for integration with standard digital systems

Applications

• Military aerospace data processing systems
• High-reliability digital memory registers
• Industrial control logic sequencing
• Ruggedized communication equipment state storage

Procurement Notes

Verify authenticity through authorized TI distributors or certified military suppliers due to limited availability. Confirm MIL-M-38510 compliance and lot traceability. Check for specific screening levels required by your program. Ensure packaging integrity matches CDIP specifications. Validate date codes against current obsolescence notices.

Selection Notes

Select this component when dual independent storage with direct clear/preset functionality is required in harsh environments. Compare propagation delays and power consumption against SN54LS or SN54H alternatives if lower power is needed. Ensure voltage margins accommodate the 4.5V to 5.5V operational window. Verify thermal management capabilities for the -55°C to +125°C range.

Part Context

This part belongs to the SN54F family of high-speed Schottky logic devices. It shares functional similarities with commercial SN54F74 variants but differs in packaging, screening, and environmental ratings. The M38510 designation indicates compliance with MIL-M-38510 standards for integrated circuits. It serves as a critical component in legacy military digital designs requiring robust flip-flop operations.

Replacement Considerations

Direct substitutes include JM38510/34101BCA and M38510/34101B2A. Cross-reference SN54F74J datasheets for electrical compatibility. Verify pinout alignment and package dimensions before substitution. Confirm that alternative parts meet the same military temperature and voltage specifications.
