SNJ54ACT11074FK

Flip Flops Overview

The SNJ54ACT11074FK is a dual positive-edge-triggered D-type flip-flop from the Texas Instruments 74ACT logic family. It features TTL-compatible inputs and CMOS outputs, housed in a 20-lead ceramic flatpack (FK) package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an industrial temperature range of -55 °C to +125 °C. Key electrical characteristics include a propagation delay of 8.5 ns and output drive currents of ±24 mA.

Flip Flops Feature Summary

• Dual independent D-type flip-flops with positive-edge clock triggering
• TTL-compatible input thresholds for direct interfacing
• CMOS outputs providing high noise immunity
• Military-grade ceramic packaging for extreme environmental reliability

Flip Flops Applications

• Military aerospace data acquisition systems
• High-reliability communication equipment
• Industrial control logic registers
• Spacecraft telemetry storage units

Flip Flops Procurement Notes

Verify the 'SNJ' prefix indicates military-grade qualification and ceramic construction. Confirm the FK suffix corresponds to the 20-lead flatpack variant. Ensure compatibility with -55 °C to +125 °C operational requirements. Check for specific military lot traceability documentation upon order confirmation.

Flip Flops Selection Notes

Select this component when military-grade radiation hardness and wide temperature tolerance are required. The ACT series offers faster switching than standard AC logic while maintaining CMOS power efficiency. The ceramic package provides superior hermetic sealing compared to plastic alternatives for harsh environments.

Flip Flops Part Context

This part belongs to the 74ACT family, bridging the speed of Schottky TTL with the low power of CMOS. The SNJ designation signifies a military-qualified version manufactured by Texas Instruments, distinct from commercial grade parts which lack the extended temperature range and rigorous testing protocols.

Flip Flops Replacement Considerations

Direct substitutes include other military-qualified dual D-type flip-flops in ceramic packages such as the SN54ACT11074FK. Verify pinout compatibility and ensure the replacement meets the same -55 °C to +125 °C operating temperature specifications.
