74HC73D,652

Overview

The Nexperia 74HC73D,652 is a dual D-type flip-flop with clear (reset) functionality, manufactured by Nexperia USA Inc. It belongs to the 74HC series of high-speed CMOS logic devices. The component operates within a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 86 MHz at 5 V. It features low power dissipation and high noise immunity. The device is housed in a 14-pin SO package (SO14), designed for surface-mount technology applications.

Feature Summary

• Dual D-type flip-flop architecture with independent clear inputs
• High-speed CMOS operation compatible with standard CMOS outputs
• Wide operating supply voltage range from 2 V to 6 V
• Low power consumption and high noise immunity characteristics

Applications

• Data storage and register circuits
• Shift registers and counters
• Parallel-to-serial data conversion
• Timing control logic in digital systems

Procurement Notes

Verify the specific suffix '652' against the manufacturer's current datasheet to confirm package type and RoHS compliance status. Ensure that the ordering information matches the exact pinout and electrical specifications required for your circuit design. Cross-reference with official Nexperia documentation to avoid discrepancies in part identification.

Selection Notes

Select this component when a dual D-type flip-flop with asynchronous reset is required in a high-speed CMOS environment. Consider the 2 V to 6 V supply range for flexibility in system voltage levels. Evaluate the 14-pin SO package constraints for PCB layout space. Compare propagation delay and power dissipation metrics against alternative logic families if performance thresholds are critical.

Part Context

This part is a member of the widely adopted 74HC logic family, known for compatibility with TTL inputs while maintaining CMOS output levels. The 74HC73 variant specifically provides two independent D-type flip-flops, making it suitable for sequential logic designs. The 'D,652' designation indicates the specific packaging and trailing configuration provided by Nexperia.

Replacement Considerations

Check for direct equivalents such as the SN74HC73 or CD74HC73 from other manufacturers. Verify pin compatibility and electrical parameter alignment before substitution. Ensure that any replacement part meets the same voltage and speed requirements specified for the original design.
