74AHC273BQ,115

Overview

The Nexperia 74AHC273BQ,115 is a D-Type Edge Triggered Flip-Flop belonging to the 74AHC logic series. It features eight non-inverting outputs and operates within a supply voltage range of 2 V to 5.5 V. The component provides an output current capability of 8 mA for both high and low states. Propagation delay is specified at 4.2 ns when operating at 5 V. It is housed in a 20-DHVQFN package with dimensions of 4.5x2.5 mm and supports surface mount installation. The device functions reliably across an extended temperature range from -40 C to +125 C.

Feature Summary

• Single circuit configuration containing eight D-type flip-flops
• Edge-triggered operation with non-inverting output polarity
• Wide supply voltage compatibility spanning 2 V to 5.5 V
• Robust thermal performance supporting up to 125 C ambient temperature

Applications

• Parallel data storage in digital systems
• Shift register construction
• Memory buffer implementation
• Timing control circuits

Procurement Notes

Verify the specific suffix 115 corresponds to the DHVQFN-20 packaging format during acquisition. Confirm that the ordered part matches the 74AHC series specifications rather than AHCT or HC variants. Ensure the procurement documentation references the correct manufacturer designation Nexperia USA Inc. to avoid substitution errors with functionally similar but electrically distinct components.

Selection Notes

Select this component when a wide voltage range including lower voltages down to 2 V is required. The 74AHC series offers higher speed compared to standard HC logic while maintaining CMOS power characteristics. Consider the 20-DHVQFN package size constraints and ensure adequate thermal management for operation near the maximum 125 C limit. Verify input signal levels align with the AHC logic family thresholds.

Part Context

This part belongs to the 74AHC family of high-speed CMOS logic devices manufactured by Nexperia. The 74AHC273 variant specifically implements octal D-type flip-flops with a common clock. The BQ suffix indicates the DHVQFN package type, distinguishing it from other physical form factors like TSSOP or SO. This series is designed for applications requiring fast switching speeds and broad voltage tolerance.

Replacement Considerations

The 74AHCT273BQ,115 serves as a pin-compatible alternative within the same package family. Note that the AHCT series requires a 4.5 V to 5.5 V supply range, unlike the 2 V minimum of the AHC series. Verify logic level compatibility before substituting, as input thresholds differ between AHC and AHCT families.
