Overview
The Texas Instruments 5962-8752501MDA is a military-grade dual positive-edge-triggered D-type flip-flop featuring clear and preset functions. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes ACT logic technology. The component is housed in a 14-pin Ceramic Flat Pack (CFP) package, designated as W style. It supports an extended industrial temperature range from -55°C to +125°C. Key electrical specifications include a maximum propagation delay of 10.5 ns at 5 V and TTL-voltage compatible inputs that accept voltages up to 5.5 V.
Feature Summary
- Dual positive-edge-triggered D-type flip-flop architecture with independent clear and preset controls
- ACT logic technology ensuring high-speed performance with low power consumption
- Military-grade reliability with extended temperature rating for harsh environments
- TTL-compatible input thresholds allowing direct interfacing with standard logic families
Applications
- Military avionics data storage systems
- Spacecraft command and control registers
- High-reliability industrial communication interfaces
- Ruggedized computing memory elements
Procurement Notes
Verify the specific suffix MDA against official Texas Instruments documentation to confirm the ceramic flat pack configuration and military qualification level. Ensure compatibility with existing board layouts for the 14-lead CFP footprint. Confirm that the procurement channel provides traceable documentation for military-grade components. Validate that the received units match the active status indicated in current TI product selection guides.
Selection Notes
Select this component when dual D-type storage with asynchronous control is required in space-constrained military applications. The ACT series offers a balance of speed and power suitable for complex digital systems. Consider the CFP package for superior thermal dissipation and hermetic sealing compared to plastic alternatives. Verify that the 4.5 V to 5.5 V operating range aligns with the system power distribution network.
Part Context
This part belongs to the SN54ACT74 family, which defines the functional logic of dual D-type flip-flops. The 5962 prefix indicates it is a Department of Defense microcircuit drawing number, signifying military or aerospace qualification. The MDA suffix specifies the particular package type and temperature grade within the broader SN54ACT product line manufactured by Texas Instruments.
Replacement Considerations
Direct replacements must maintain the SN54ACT74 functionality and 14-lead CFP package. Verify that any substitute part meets the same -55°C to +125°C temperature range and 4.5 V to 5.5 V voltage requirements. Cross-reference with other manufacturers offering equivalent MIL-spec ACT logic devices.
