74HC273D,652

Overview

The Nexperia 74HC273D,652 is an octal D-type flip-flop with a master reset function. It operates within a supply voltage range of 2.0 V to 6.0 V and features positive-edge triggering on the clock input. The device provides eight non-inverting outputs that reflect data inputs upon valid clock transitions. A low signal on the master reset input forces all outputs low independently of other signals. It supports operation from -40 °C to +125 °C and includes ESD protection exceeding 2000 V (HBM).

Feature Summary

• Octal configuration with eight independent positive-edge triggered D-type flip-flops sharing a common clock and master reset.
• Wide operating supply voltage range supporting 2.0 V to 6.0 V for flexible system integration.
• High noise immunity and latch-up performance exceeding 100 mA per JESD 78 Class II Level B standards.

Applications

• Parallel-to-serial data conversion circuits
• General-purpose storage registers in digital systems
• Shift register configurations for data handling

Procurement Notes

Verify the specific ordering suffix '652' to ensure correct package type and tape/reel specifications. Confirm availability status as manufacturing schedules may change. Check RoHS compliance documentation for environmental requirements. Ensure interface voltage levels match CMOS input specifications for reliable logic operation.

Selection Notes

Select this component when an octal storage solution with a global reset is required. Consider the 74HCT273 variant if TTL input levels are necessary instead of CMOS. Evaluate the SOIC-20 package dimensions against PCB layout constraints. Verify thermal dissipation capabilities for high-density designs.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by Nexperia. It implements standard octal D-type flip-flop functionality compatible with JEDEC standards. The device is designed for general-purpose digital applications requiring parallel data storage and synchronization.

Replacement Considerations

The 74HC273DB variant offers identical electrical characteristics but utilizes a different surface-mount package option. Cross-reference datasheets to confirm pinout compatibility and physical footprint differences before substitution.
