SNJ54AC374FK

Flip Flops Overview

The SNJ54AC374FK is an octal D-type transparent latch with three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features a propagation delay of 11 ns at 5 V. The device supports low-level enable control and provides high drive strength with output currents of ±24 mA. It is housed in a 20-lead Ceramic Quad Flat Pack (LCCC) package and is rated for operation across the military temperature range of -55°C to 125°C.

Flip Flops Feature Summary

• Octal D-type transparent latch architecture with eight independent data paths
• Three-state outputs allowing direct bus interfacing without external buffers
• Low-level enable input controls data transparency relative to the clock signal
• High current drive capability supporting robust load conditions

Flip Flops Applications

• Military-grade digital logic systems requiring extended temperature stability
• Bus-oriented memory register configurations
• High-speed data buffering applications in aerospace environments
• Parallel-to-serial conversion circuits in defense electronics

Flip Flops Procurement Notes

Verify the specific ordering suffix FK against official Texas Instruments documentation to confirm the ceramic quad flat pack package configuration and lead-free status. Ensure that the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity. Cross-reference the date code and lot number with factory records to validate compliance with the specified military temperature rating and electrical characteristics prior to integration.

Flip Flops Selection Notes

Select this component when designing systems that require transparent latching behavior rather than edge-triggered storage. The AC series offers a balance of speed and power consumption suitable for 2V to 6V operations. Consider the LCCC package constraints for thermal management and board space. Verify that the low-enable logic polarity aligns with the system's control signaling requirements before finalizing the design.

Flip Flops Part Context

This part belongs to the SN54/74AC374 family of octal latches. It shares functional similarities with other AC series devices but differs in package type and environmental rating. The SNJ prefix indicates a military-grade variant, distinguishing it from commercial counterparts like the SN74AC374. It serves as a foundational building block for complex sequential logic designs in specialized industrial and defense sectors.
