SNJ54ABT273W

The SNJ54ABT273W is a military-grade octal D-type flip-flop manufactured by Texas Instruments, providing eight edge-triggered data storage elements with a common clock and a synchronous master reset function in a ceramic flatpack (CFP) package. As a member of the ABT advanced BiCMOS logic family, it delivers a balanced combination of high-speed operation and low power dissipation, with TTL-compatible inputs and full ±48 mA output drive capability suited for heavily loaded backplanes. The CFP package ensures excellent thermal and environmental resilience, meeting the hermeticity requirements essential for high-reliability systems, and the device operates over the full -55 °C to 125 °C military temperature range.

Typical applications for this component include avionics flight control units, radar signal processing chains, and secure communications payloads where rad-hard or radiation-tolerant logic is not required but robust, deterministic sequential logic is mandatory. Design engineers commonly deploy these flip-flops as temporary data registers, pipeline stages in digital signal paths, or state-machine building blocks in mission-critical embedded computing. Procurement considerations center on the SNJ54 identifier, which designates QML Class Q processing with full military pedigree per MIL-PRF-38535, substantially reducing false part or counterfeit risk compared to commercial-off-the-shelf alternatives; buyers also evaluate TI’s continued active production support for this device family against program lifecycles and coordinate with authorized defense supply chain partners to ensure proper ESDS handling and traceability documentation.
