SN74HC74PWG4

Flip Flops Overview

The SN74HC74PWG4 is a dual D-type positive-edge-triggered flip-flop manufactured by Texas Instruments. It features independent data (D), clock (CLK), preset (PRE), and clear (CLR) inputs for each flip-flop, along with complementary Q and Q outputs. The device operates within a supply voltage range of 2 V to 6 V and supports a maximum operating temperature of 85 °C. Packaged in a 14-pin TSSOP, it provides high-speed performance suitable for various digital logic applications requiring reliable state storage.

Flip Flops Feature Summary

• Dual configuration containing two independent D-type flip-flops within a single package
• Positive-edge triggering mechanism synchronized by the clock input signal
• Asynchronous active-low preset and clear functions for immediate state control
• Complementary outputs provide both true and inverted logic states simultaneously

Flip Flops Applications

• Data storage and register implementation in digital circuits
• Frequency division and pulse synchronization tasks
• Shift register construction for serial-to-parallel conversion
• State machine sequencing and control logic elements

Flip Flops Procurement Notes

Verify the specific suffix G4 indicates compliance with RoHS directives and restricted substance requirements. Confirm the package marking aligns with the 14-pin TSSOP physical dimensions. Ensure the ordering part number matches the exact HC series specification required for your design. Cross-reference the manufacturer datasheet for any recent pinout or electrical characteristic updates before finalizing procurement.

Flip Flops Selection Notes

Select this component when a dual flip-flop solution is required within space-constrained designs utilizing surface-mount technology. The HC series offers compatibility with standard CMOS logic levels across a wide voltage range. Consider the propagation delay characteristics relative to your system clock speed. Verify that the asynchronous control inputs meet the timing requirements of your application architecture.

Flip Flops Part Context

This component belongs to the SN74HCxx family of high-speed CMOS logic devices produced by Texas Instruments. The HC series is designed for general-purpose digital applications offering fast switching speeds and low power consumption. The SN74HC74 variant specifically addresses needs for dual bistable latching elements. The PWG4 suffix denotes the specific tape-and-reel packaging and environmental compliance status.

Flip Flops Replacement Considerations

Direct substitutes include SN74HC74PWR and SN74HC74N. Alternative packages such as SOIC-14 may require schematic review. Verify pin compatibility and electrical parameters match before substitution. Check availability of equivalent automotive or industrial grade variants if environmental conditions differ.
