SN74AS74ANS

Flip Flops Overview

The SN74AS74ANS is a dual positive-edge-triggered D-type flip-flop from the Texas Instruments SN74AS series. It features TTL-compatible inputs and outputs, housed in a 14-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 9 ns, a high-level output current of -2 mA, and a low-level output current of 20 mA. It supports both inverting and non-inverting outputs and functions within an operating temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Dual positive-edge-triggered D-type flip-flop configuration
• TTL-compatible input and output logic levels
• Schottky-clamped design for high-speed switching performance

Flip Flops Applications

• Parallel data storage and buffering
• Shift register construction
• Timing control circuits

Flip Flops Procurement Notes

Verify the specific suffix 'N' indicates a plastic DIP package variant rather than the 'SR' tape-and-reel SOIC version found in other listings. Confirm RoHS compliance status directly with the manufacturer or authorized distributor, as datasheet references may vary by production batch. Ensure the ordering part number matches the required package type and lead-free specifications for your assembly process.

Flip Flops Selection Notes

Select this component when dual independent D-type flip-flops are required with Schottky speed characteristics. It is suitable for designs needing TTL compatibility and moderate drive strength. Consider the 14-pin DIP package constraint if through-hole mounting is mandatory. Compare against SN74LS74A for slower, lower-power alternatives or SN74AS74ANSR for surface-mount requirements.

Flip Flops Part Context

This part belongs to the SN74AS (Advanced Schottky) family, known for faster switching speeds compared to standard LS logic. The SN74AS74A variant specifically provides two independent flip-flops in a single package. It serves as a high-speed alternative to the SN74LS74A, offering improved propagation delays while maintaining similar pinouts and logical functionality for backward compatibility in mixed-logic designs.
