SN74HCT74AN

Flip Flops Overview

The SN74HCT74AN is a dual D-type positive-edge-triggered flip-flop from Texas Instruments' HCT logic family. It integrates two independent circuits within a 14-pin DIP package, featuring TTL-compatible inputs and CMOS outputs. The device operates at a supply voltage of 4.5 V to 5.5 V, with a maximum propagation delay of 28 ns and output currents of ±4 mA. It supports preset and clear functions, functioning reliably across an industrial temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Dual D-type positive-edge-triggered flip-flops with complementary outputs
• TTL-compatible input levels for direct interfacing with standard logic families
• Integrated asynchronous preset and clear control inputs

Flip Flops Applications

• Parallel-to-serial data conversion circuits

• Frequency division and counting applications

Flip Flops Procurement Notes

Verify the specific manufacturer prefix (SN vs. CD) and suffix against the official datasheet to ensure compatibility with the intended design requirements. Confirm that the PDIP-14 package variant matches the board layout specifications. Cross-reference the RoHS compliance status and lead-free markings as required by project regulations before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when TTL-level input compatibility is required alongside CMOS output drive capabilities. The HCT series ensures noise immunity suitable for industrial environments while maintaining low power consumption. Ensure the application does not exceed the specified maximum operating frequency or current limits defined in the electrical characteristics table.

Flip Flops Part Context

This part belongs to the SNx4HCT74 family of dual D-type flip-flops manufactured by Texas Instruments. It is designed for general-purpose digital logic applications requiring reliable state storage and transfer. The HCT technology bridges the gap between older TTL standards and modern CMOS performance, offering robust operation in mixed-voltage systems.

Flip Flops Replacement Considerations

Compatible substitutes include SN74HC74N and SN74HCT74PWG4. Verify pinout consistency and electrical parameter alignment before substitution.
