SN74HC74APWR

Flip Flops Overview

The SN74HC74APWR is a dual D-type flip-flop from Texas Instruments, utilizing high-speed CMOS technology. It operates within a supply voltage range of 2 V to 6 V and features independent clock (CLK), preset (PRE), and clear (CLR) inputs for each flip-flop. The device provides complementary outputs (Q and Q-bar). Key electrical parameters include a propagation delay of 175 ns, with high-level and low-level output currents of -5.2 mA and 5.2 mA respectively. It is housed in a 14-TSSOP package and supports surface-mount installation.

Flip Flops Feature Summary

• Dual D-type positive-edge-triggered flip-flops with separate control inputs
• High-speed CMOS operation compatible with standard logic families
• Independent asynchronous preset and clear functions

Flip Flops Applications

• Data storage and register applications
• Shift registers and counters
• Timing and synchronization circuits

Flip Flops Procurement Notes

Verify the specific suffix 'A' against official Texas Instruments documentation to confirm it denotes an approved automotive or enhanced variant rather than a generic commercial part. Ensure the ordering code matches the exact package type and temperature rating required for your design. Cross-reference the manufacturer's latest datasheet revision history to confirm current availability and any potential form-fit-function changes.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop solution is required with a wide operating voltage range. It is suitable for designs needing independent set and reset capabilities without external gating logic. Consider the 14-TSSOP package constraints and thermal performance if multiple devices are placed closely on the PCB. Verify that the input voltage levels match the system's logic standards.

Flip Flops Part Context

This part belongs to the SN74HC series of high-speed CMOS logic devices produced by Texas Instruments. The HC series is known for its compatibility with TTL inputs while offering lower power consumption compared to older LS technologies. The 'A' suffix typically indicates specific manufacturing or qualification attributes defined by the manufacturer, distinguishing it from the base SN74HC74PWR model.

Flip Flops Replacement Considerations

The SN74HC74PWR is a direct functional equivalent within the same family but may lack specific automotive or enhanced qualifications associated with the 'A' suffix. Other manufacturers offer pin-compatible alternatives such as the CD4044B or 74HC74 from ON Semiconductor, though parameter variations should be verified.
