SN74HC74PWT

Flip Flops Overview

The SN74HC74PWT is a dual D-type edge-triggered flip-flop from the Texas Instruments 74HC series, housed in a 14-TSSOP package. It operates on a supply voltage range of 2V to 6V with a maximum clock frequency of 60 MHz. Key electrical parameters include a propagation delay of 30 ns at 6V with 50pF load, output currents of ±5.2 mA, and static current of 4 µA. The device supports positive-edge triggering with set and reset functions, featuring non-inverting outputs and an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Dual D-type edge-triggered flip-flops with independent set and reset inputs
• High-speed operation with 60 MHz maximum clock frequency
• Wide supply voltage compatibility ranging from 2V to 6V
• Low static power consumption with 4 µA typical current draw

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• Digital state storage and memory elements

Flip Flops Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific packaging variants such as tape-and-reel quantities. Ensure the ordering suffix matches the required TSSOP-14 package dimensions. Review technical datasheets for latest pinout configurations and electrical characteristics before integration into design specifications.

Flip Flops Selection Notes

Select this component when dual independent flip-flops are required within a compact surface-mount footprint. The HC series offers CMOS compatibility with TTL input levels, suitable for mixed-voltage interfaces. Consider the 2V to 6V operating range for flexibility in low-power or standard logic applications. Evaluate the 30 ns propagation delay against system timing requirements to ensure adequate setup and hold times are met.

Flip Flops Part Context

This part belongs to the widely adopted 74HC logic family, known for high-speed CMOS technology. It serves as a fundamental building block for sequential logic designs. The TSSOP-14 package provides a space-efficient solution for modern PCB layouts compared to traditional DIP packages. It is commonly used in consumer electronics, industrial control, and telecommunications equipment requiring reliable digital storage.

Flip Flops Replacement Considerations

SN74HC74PW: Same logic function and package but may differ in manufacturing lot or minor specification tolerances. SN74HC74N: Pin-compatible alternative in PDIP-14 package for through-hole applications. Verify electrical parameters and package dimensions before substitution.
