SNJ54ABT377J

Flip Flops Overview

The SNJ54ABT377J is an octal edge-triggered D-type flip-flop manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and features non-inverting outputs. The component is housed in a 20-pin CDIP package, suitable for through-hole mounting. It supports a maximum clock frequency of 150 MHz and exhibits a propagation delay of 6.8ns at 5V with 50pF load. The device functions reliably across a military-grade temperature range of -55°C to +125°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single package
• Edge-triggered operation synchronized with the positive clock transition
• Military-grade reliability designed for extreme environmental conditions

Flip Flops Applications

• High-reliability aerospace data storage systems
• Defense communication equipment signal processing
• Industrial control logic state retention

Flip Flops Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status as per current manufacturing standards. Ensure the procurement channel provides valid traceability documentation for military-grade components. Check for any specific handling requirements related to the ceramic dual in-line package structure.

Flip Flops Selection Notes

Select this component when high-speed octal data latching is required in harsh environments. The ABT series offers superior speed compared to standard TTL equivalents. Consider the through-hole mounting constraint if PCB space allows. Evaluate the 32mA output drive capability against bus loading requirements for the specific application circuit design.

Flip Flops Part Context

This part belongs to the SN54/74ABT series of high-speed logic devices. It serves as a robust alternative to lower-speed families for critical timing applications. The J suffix denotes the ceramic dual in-line package variant, distinct from plastic or surface-mount options. It complements other octal logic components within the same industrial and military product line.

Flip Flops Replacement Considerations

Direct substitutes include SN54ABT377AJ and SN54ABT377BJ variants which share identical electrical specifications but may differ in package tolerance or testing levels. Cross-reference with SN54ACT377J only if AC logic compatibility is verified, noting potential differences in switching characteristics.
