74HCT273BQ,115

Overview

The Nexperia 74HCT273BQ,115 is an 8-bit D-type flip-flop with positive-edge triggering and a master reset function. It operates within a supply voltage range of 4.5V to 5.5V. The device features non-inverting outputs with current drive capabilities of 4mA (high) and 5.2mA (low). It exhibits a maximum propagation delay of 30ns at 4.5V with 50pF load and supports clock frequencies up to 36 MHz. Static current consumption is 8 µA. The component is housed in a 20-DHVQFN package and is rated for operation between -40°C and +125°C.

Feature Summary

• Positive-edge triggered D-type architecture with integrated master reset functionality
• Non-inverting output configuration providing direct data state reflection
• Automotive-grade qualification ensuring reliability under extended temperature conditions

Applications

• Automotive electronic systems requiring AEC-Q100 compliant logic components
• Data storage circuits utilizing parallel input and synchronous output operations
• Industrial control interfaces managing digital signal latching and buffering

Procurement Notes

Verify the specific suffix 'BQ,115' corresponds to the DHVQFN-20 package variant during sourcing. Confirm AEC-Q100 certification status if automotive compliance is mandatory for the target application. Ensure design compatibility with the 4.5V to 5.5V supply voltage range and check thermal dissipation requirements for the surface-mount package.

Selection Notes

Select this component when a robust 8-bit register is needed for automotive or industrial environments. It offers higher noise immunity compared to standard HC series due to HCT input levels. Consider alternative packages like TSSOP or SOIC if the DHVQFN footprint is unsuitable. Verify that the 36 MHz maximum frequency meets system timing constraints.

Part Context

This part belongs to the 74HCT273 family of octal D-type flip-flops. It shares functional similarities with other 74HCT series devices but is distinguished by its specific automotive qualification and compact leadless package. It serves as a digital storage element within larger logic networks, often paired with bus transceivers or decoders in complex embedded designs.
