SN74HC74DR

Flip Flops Overview

The SN74HC74DR is a dual D-type flip-flop from the Texas Instruments SN74HC series, housed in a 16-pin SOIC package. It features Schmitt-trigger inputs for noise filtering and push-pull outputs. The device operates within a supply voltage range of 2 V to 6 V and supports propagation delays of 18 ns at 5 V. It functions across an industrial temperature range of -40°C to +85°C with a maximum clock frequency of 38 MHz.

Flip Flops Feature Summary

• Dual independent D-type flip-flops with separate data, clock, and reset terminals
• Schmitt-trigger action on all inputs provides tolerance to slow input rise times
• Push-pull output structure ensures strong drive capability for low impedance loads

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations for data storage and transfer
• General-purpose memory elements in digital logic systems

Flip Flops Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop with Schmitt-trigger inputs is required for noise immunity. It is suitable for applications needing operation across a wide voltage range of 2 V to 6 V. Consider the 16-pin SOIC package for surface-mount assembly constraints and thermal performance needs.
