74HC174D,652

Overview

The Nexperia 74HC174D,652 is a hex D-type flip-flop featuring positive-edge triggering and an asynchronous master reset. It operates within a supply voltage range of 2V to 6V and utilizes a 16-SOIC surface-mount package. The device provides non-inverting outputs with a maximum propagation delay of 23ns at 6V. It supports a clock frequency up to 66 MHz and functions reliably across an extended temperature range from -55°C to 125°C.

Feature Summary

• Contains six independent D-type flip-flops with positive-edge clocking
• Includes an asynchronous master reset input for immediate state clearing
• Provides non-inverting outputs suitable for direct logic interfacing

Applications

• Parallel data storage in digital systems
• Shift register construction for serial-to-parallel conversion
• State machine implementation in control circuits

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS3 compliance requirements for your assembly process. Confirm availability status as distribution channels may vary. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a compact solution for multiple parallel data storage elements is required. The wide operating voltage range allows compatibility with various logic families. Consider the 16-pin SOIC footprint for PCB layout constraints. Verify that the asynchronous reset functionality aligns with the system's power-up or fault-clearing requirements compared to synchronous alternatives.
