Flip Flops datasheet and documents for SNJ54ABT821JT

SNJ54ABT821JT

Flip Flops Overview

The SNJ54ABT821JT is a military-grade bus interface flip-flop from Texas Instruments, belonging to the ABT logic series. It features ten non-inverting D-type inputs and three-state outputs within a single circuit configuration. The device operates on a supply voltage range of 4.5 V to 5.5 V and supports surface mount installation in a 24-lead CDIP package. It ensures reliable performance across an extended temperature range from -55°C to +125°C, with a typical propagation delay of 6.2 ns at 5 V.

Flip Flops Feature Summary

Provides high-speed data storage for ten-bit bus applications using edge-triggered D-type latching mechanisms.
Features three-state outputs that allow direct connection to multiplexed data buses without external switching components.
Designed for military specifications with extended thermal stability suitable for harsh operational environments.

Flip Flops Applications

Military communication systems requiring robust data buffering
Aerospace instrumentation bus interfaces
High-reliability computer memory address registers

Flip Flops Procurement Notes

Verify the specific suffix 'JT' corresponds to the ceramic dual in-line package (CDIP) variant intended for military or aerospace qualification. Confirm RoHS compliance status as military parts may differ from commercial standards. Ensure the supplier provides traceability documentation required for defense contracts. Check for availability of official datasheets confirming the -55°C to +125°C operating range.

Flip Flops Selection Notes

Select this component when designing systems that require high-density bus interfacing with strict environmental tolerances. The ABT series offers faster switching speeds compared to standard TTL logic. Consider the physical dimensions of the 24-lead CDIP package for PCB layout constraints. Evaluate power consumption requirements against the specified static current limits for the target application.

Flip Flops Part Context

This part belongs to the SN54/74ABT family of high-speed CMOS logic devices. The SNJ prefix indicates a military-grade version manufactured under strict quality controls. It complements other bus drivers and latches in the same series, providing standardized interfaces for complex digital systems requiring high noise immunity and speed.
