74HCT175D,652

Overview

The Nexperia 74HCT175D,652 is a quadruple D-type flip-flop with separate clock and clear inputs, manufactured in the HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 30 MHz at 5 V. The device features low power dissipation and high noise immunity, complying with JEDEC standards for CMOS levels. It is housed in a 16-pin SO package (SOP16) and is specified for operation across an extended temperature range from -40 °C to +125 °C.

Feature Summary

• Quadruple D-type flip-flop architecture with independent clock and asynchronous clear functions
• HCT logic compatibility providing TTL-compatible input levels while maintaining CMOS output drive characteristics
• Extended industrial temperature rating supporting reliable operation in harsh thermal environments

Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations for digital signal processing
• General-purpose storage elements in microprocessor-based systems

Procurement Notes

Verify the specific ordering code suffix against current Nexperia documentation to confirm package type and reel specifications. Confirm RoHS compliance status and halogen-free classification requirements prior to finalizing procurement orders. Ensure that the intended operating voltage aligns strictly with the HCT family limits to prevent functional degradation or device damage during integration.

Selection Notes

Select this component when TTL-level interface compatibility is required alongside standard CMOS performance metrics. The HCT series ensures direct interfacing with older TTL logic families without additional level shifting components. Consider the extended temperature range if the application environment exceeds standard commercial limits. Verify pinout compatibility with existing PCB footprints before implementation.

Part Context

This component belongs to the widely adopted 74HC/HCT logic family, ensuring broad ecosystem support and cross-manufacturer pin compatibility. The 74HCT175 variant specifically addresses applications needing robust clocked storage with clear functionality. Its prevalence in industrial and consumer electronics makes it a standard choice for general-purpose digital logic design requiring reliable state retention.

Replacement Considerations

Direct substitutes include equivalent parts from other manufacturers such as SN74HCT175 or MC74HCT175, provided pinouts and electrical characteristics match exactly. Verify that alternative sources maintain the same SOP16 package dimensions and thermal ratings to ensure mechanical fit and reliability.
