SNJ54ACT374W

Flip Flops Overview

The SNJ54ACT374W is an octal edge-triggered D-type flip-flop featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 10 ns. The device provides high-level output current of -24 mA and low-level output current of 24 mA. It is housed in a 20-CDIP package and functions across an extended temperature range from -55°C to +125°C.

Flip Flops Feature Summary

• Octal D-type edge-triggered configuration with eight independent storage elements
• Three-state outputs for effective bus driving and system isolation
• TTL-compatible inputs ensuring direct interface with standard logic families
• Extended military-grade temperature rating for harsh environment reliability

Flip Flops Applications

• Military aerospace data acquisition systems requiring wide temperature tolerance
• High-reliability industrial control bus interfaces
• Defense communication equipment register banks
• Spacecraft telemetry data latching circuits

Flip Flops Procurement Notes

Verify the specific suffix 'W' corresponds to the ceramic flatpack (CFP/DFP) package variant rather than the CDIP version when sourcing. Confirm that the component meets the required military qualification standards, as commercial equivalents lack the specified -55°C to +125°C operating range. Ensure compatibility with existing board layouts for the 20-pin through-hole footprint before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when designing systems that demand robust performance under extreme thermal conditions typical of military or aerospace applications. The ACT series offers speed comparable to ALS logic while maintaining CMOS power efficiency. Choose this part over standard 74-series variants if the application requires guaranteed operation at temperatures below -40°C or above +85°C.

Flip Flops Part Context

This device belongs to the SN54ACT family of high-speed CMOS logic products. It serves as a critical memory element in digital systems, providing parallel data storage capabilities. The SNJ prefix indicates a military-grade screening level, distinguishing it from commercial SN74 counterparts which typically have narrower operating temperature ranges and less rigorous manufacturing controls.
