SN74AHCT174NSR

Flip Flops Overview

The SN74AHCT174NSR is a hex D-type flip-flop from Texas Instruments' 74AHCT logic family, housed in a 16-pin SOIC package. It features edge-triggered operation with an asynchronous master reset input and non-inverting outputs. The device operates within a 4.5V to 5.5V supply range, supporting TTL-compatible inputs for seamless integration with standard logic systems. Key electrical parameters include a maximum propagation delay of 8.8ns at 5V with 50pF load, output drive currents of ±8mA, and a static current of 4µA. It functions reliably across an industrial temperature range of -40°C to +85°C.

Flip Flops Feature Summary

Flip Flops Procurement Notes

Verify the specific suffix 'SR' indicates reel packaging when sourcing components. Confirm that the operating voltage requirements align strictly with the 4.5V to 5.5V specification to ensure proper TTL compatibility. Check datasheet revisions for any updates regarding thermal performance or pinout consistency before finalizing procurement specifications.

Flip Flops Selection Notes

Select this component when a hex configuration is required alongside TTL-compatible input thresholds. The AHCT series bridges CMOS speed with TTL voltage levels, making it suitable for mixed-logic environments. Ensure the design accommodates the 16-pin SOIC footprint and considers the 8.8ns propagation delay for timing-critical applications within the specified temperature range.

Flip Flops Part Context

This part belongs to the SN74AHCT174 series, representing a specialized variant of the widely used 74-series logic family. It combines the high-speed performance characteristics of AHC technology with the voltage tolerance of HC/TTL standards. The NSR designation identifies the surface-mount SOIC package variant, distinguishing it from through-hole DIP alternatives within the same logical function set.
