74HC174DB,118

Overview

The Nexperia 74HC174DB,118 is a hex D-type flip-flop with reset, part of the 74HC series. It features six independent D-type flip-flops in a single package, providing positive-edge triggering and an asynchronous master reset. The device operates within a supply voltage range of 2 V to 6 V and supports input voltages up to 6 V. It is housed in a 16-SSOP package and offers high noise immunity and low static power consumption.

Feature Summary

• Contains six independent D-type flip-flops with positive-edge clock triggering
• Includes an asynchronous master reset function for immediate state initialization
• Provides high noise immunity and low static power consumption typical of HC logic
• Supports input voltage levels up to 6 V regardless of VCC

Applications

• Parallel data storage and register applications
• Shift register configurations for serial-to-parallel conversion
• Timing control circuits requiring synchronized state retention
• Digital signal processing systems needing multiple bit storage

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notifications, as availability may be limited. Ensure the SSOP-16 package matches your PCB footprint requirements before ordering.

Selection Notes

Select this component when designing circuits requiring multiple synchronized storage elements with a common reset. Consider the 74HC series speed and voltage compatibility with your system logic levels. Verify that the SSOP-16 package fits your assembly constraints and thermal requirements.

Part Context

This component belongs to the 74HC family of high-speed CMOS logic devices. It provides standard hex D-flip-flop functionality compatible with various digital systems. The DB suffix indicates the SSOP-16 surface-mount package variant manufactured by Nexperia.

Replacement Considerations

Public confirmed substitutes include SN74HC174PWT (Texas Instruments) and M74HC174RM13TR (STMicroelectronics). These alternatives offer similar hex D-flip-flop functionality but may differ in package type or specific electrical characteristics.
