5962-8752501MCA

Overview

The Texas Instruments 5962-8752501MCA is a military-grade logic integrated circuit belonging to the SNx4ACT74 series. It contains two dual positive-edge-triggered D-type flip-flops with independent clear and preset functions. The device operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs. Packaged in a 14-pin ceramic dual in-line (CDIP) format, it supports through-hole mounting. The component is rated for an extended industrial temperature range from -55°C to +125°C.

Feature Summary

• Dual positive-edge-triggered D-type flip-flop architecture
• Independent active-low clear and preset control inputs
• TTL-compatible input logic levels
• Military-grade reliability with ceramic packaging

Applications

• Military aerospace data storage systems
• High-reliability digital signal processing registers
• Harsh environment state machine implementations
• Secure communication protocol synchronization circuits

Procurement Notes

This component is classified as a military-grade part subject to strict quality assurance protocols. Procurement typically involves authorized government or defense contractors rather than general commercial channels. Verify that the specific ordering suffix matches the required radiation hardness and screening standards. Ensure all documentation complies with applicable defense supply chain regulations before finalizing acquisition.

Selection Notes

Select this component when designing systems requiring high-speed edge-triggered storage with robust environmental tolerance. The ACT series offers improved switching speeds compared to standard variants while maintaining CMOS power efficiency. Verify that the 14-CDIP package fits the mechanical constraints of the target chassis. Confirm that the TTL input thresholds align with the upstream logic family driving the clock and data lines.

Part Context

The 5962-8752501MCA is a cross-reference designation for the commercial SN54ACT74 device, modified for military specifications. This numbering system indicates a specific grade of the SN54ACT74 family, ensuring stricter manufacturing controls. It serves as a direct functional replacement for other military-qualified dual D-type flip-flops within the same logic family.

Replacement Considerations

Direct substitutes include other military-qualified SN54ACT74 variants with matching 14-CDIP packages. Verify pin compatibility and electrical characteristics against the original design requirements before substitution.
