74HCT174N,652

Overview

The NXP USA Inc. 74HCT174N,652 is a hex D-type flip-flop with reset, manufactured using HCT CMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and features a synchronous clear input. The device is housed in a 16-pin PDIP package and supports operation across an extended temperature range from -40 °C to +125 °C.

Feature Summary

• Hex D-type flip-flop architecture providing six independent data storage elements
• Synchronous clear function for controlled state initialization
• HCT logic compatibility ensuring TTL-level input interfacing

Applications

• Parallel data storage registers
• Shift register configurations
• State machine implementation

Procurement Notes

Verify the specific suffix '652' against current Nexperia documentation to confirm packaging and compliance status. Confirm availability as standard products may transition between manufacturers or undergo obsolescence notices. Cross-reference pinout details with official datasheets prior to PCB layout finalization.

Selection Notes

Select this component when requiring multiple synchronized storage elements with a common control signal. The HCT series ensures compatibility with legacy TTL logic levels while maintaining CMOS power efficiency. Verify package constraints and thermal requirements against the application environment before integration.

Part Context

This component belongs to the widely adopted 74HCT logic family, originally developed by Philips Semiconductors and now maintained by Nexperia. The family provides high-speed CMOS performance with TTL-compatible inputs, serving as a standard interface solution in mixed-logic digital systems.

Replacement Considerations

Check for equivalent parts such as SN74HCT174 or MC74HCT174. Ensure functional parity regarding the synchronous clear mechanism and output drive characteristics. Validate package dimensions and pin assignments for direct replacement suitability.
