SN74AHCT74PWG4

Flip Flops Overview

The SN74AHCT74PWG4 is a dual positive-edge-triggered D-type flip-flop from the Texas Instruments SN74AHCT74 family. It features TTL-compatible inputs and CMOS outputs, operating within a 4.5 V to 5.5 V supply range. The device provides independent set and reset functions with low input leakage current. Packaged in a 14-TSSOP surface-mount case, it exhibits a propagation delay of 8.8 ns and offers output drive currents of 8 mA for both high and low states.

Flip Flops Feature Summary

• Dual positive-edge-triggered D-type flip-flops with independent set and reset controls
• TTL-compatible inputs ensure direct interface with TTL logic systems
• CMOS outputs provide low power consumption and high noise immunity
• Low input leakage current characteristics enhance signal integrity

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations for data storage
• Timing control and synchronization logic
• General-purpose digital state storage applications

Flip Flops Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and pin alignment against the 14-TSSOP specification. Validate RoHS compliance documentation prior to integration. Ensure design compatibility with existing TTL input levels and 5 V supply rails. Review manufacturer obsolescence notices for long-term supply planning.

Flip Flops Selection Notes

Select this component when TTL input compatibility is required alongside CMOS output performance. The dual configuration supports space-constrained designs needing two independent storage elements. Verify that the 8.8 ns propagation delay meets system timing requirements. Ensure the 14-TSSOP footprint aligns with PCB layout constraints and thermal management needs.

Flip Flops Part Context

This part belongs to the SN74AHCT74 series, designed for high-speed digital applications requiring TTL interfacing. The AHCT logic family bridges the gap between older TTL standards and modern CMOS technologies. The PWG4 suffix indicates a specific tape-and-reel packaging variant compliant with environmental directives.

Flip Flops Replacement Considerations

SN74AHCT74PWR is a direct functional substitute within the same series offering identical electrical characteristics and pinout compatibility.
