SNJ54ACT573FK

Overview

The SNJ54ACT573FK is a military-grade octal D-type transparent latch with 3-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and features inputs compatible with TTL voltage levels. The device provides a maximum propagation delay of 9.5ns at 5V. It utilizes a 20-pin Leadless Ceramic Chip Carrier (LCCC) package designated as FK. The component supports an operating free-air temperature range from -55°C to 125°C.

Feature Summary

Octal D-type transparent latches designed for high-speed data storage applications
Three-state outputs engineered to drive highly capacitive or low-impedance loads
TTL-voltage compatible inputs allowing direct interfacing with standard logic families

Applications

Parallel data storage systems
Digital bus buffer implementations
I/O port interface circuits
Bus driver configurations

Procurement Notes

Verify the specific ordering suffix FK corresponds to the 20-pin LCCC package configuration required for your design. Confirm that the military rating aligns with your environmental specifications. Check current production status and availability through authorized distributors. Ensure proper handling precautions are observed due to the sensitivity of ceramic packages.

Selection Notes

Select this component when military-grade reliability and wide temperature operation are mandatory. The ACT series offers higher speed compared to older AC variants while maintaining similar pinouts. Consider the 3-state output capability if bus sharing is required in the system architecture. Evaluate the LCCC package suitability against available PCB footprint constraints and mounting requirements.

Part Context

This part belongs to the SN54ACT573 family, which includes catalog versions like the SN74ACT573. The SN54 prefix indicates military qualification, distinguishing it from commercial grade parts. The ACT series represents advanced CMOS technology offering improved performance over legacy AC devices. Other package options include CDIP and CFP for the military version.

Replacement Considerations

SNJ54ACT573J (CDIP package), SNJ54ACT573W (CFP package). These are functionally equivalent military-grade alternatives differing only in physical package type.
