54HC76J/B

Overview

The MC54HC76J/B is a dual D-type flip-flop manufactured by Rochester Electronics, LLC. It belongs to the 54HC series of CMOS logic devices, designed for military and aerospace applications requiring high reliability. The component features two independent D-type flip-flops with separate clock inputs and data inputs, along with shared clear and preset functions. It operates within a voltage range of 2 V to 6 V for the HC series and supports a wide operating temperature range from -55 °C to +125 °C. The device is housed in a ceramic hermetic package, ensuring durability in harsh environments.

Feature Summary

Dual D-type flip-flop configuration with independent clock and data inputs
Shared clear and preset control functions for synchronized operation
Ceramic hermetic packaging suitable for radiation-hardened environments
Wide operating temperature range supporting extreme conditions

Applications

Military avionics systems requiring radiation tolerance
Aerospace data storage and processing units
Harsh environment digital logic circuits
Spacecraft command and control logic

Procurement Notes

Verify the specific suffix 'B' against official Rochester Electronics documentation to confirm pinout compatibility and electrical specifications. Ensure the ceramic hermetic package matches the required environmental sealing standards. Cross-reference the ESCC qualification status if space-grade compliance is mandatory. Confirm lead-free status and manufacturing lot traceability for critical missions.

Selection Notes

Select this component when dual D-type flip-flop functionality is required in radiation-hardened or high-reliability applications. The 54HC series offers broader voltage flexibility compared to HCT variants. Consider the ceramic package for thermal stability and hermetic sealing needs. Evaluate power consumption and switching speed requirements against the 54HC series specifications.

Part Context

The MC54HC76 is part of the 54HC family of CMOS logic ICs, specifically designed for military and aerospace use. These devices are known for their robustness against radiation and extreme temperatures. Rochester Electronics provides these components as a source of supply for legacy and specialized military specifications, often maintaining production capabilities for long-term procurement needs.
