74LVC273BQ,115

Overview

The 74LVC273BQ,115 is a D-type edge-triggered flip-flop from the Nexperia AHC logic series. It features eight non-inverting outputs and operates within a supply voltage range of 2 V to 5.5 V. The device provides an output drive capability of ±8 mA at both high and low states. Propagation delay is specified at 4.2 ns when operating at 5 V. It is housed in a DHVQFN-20 surface-mount package and supports an extended industrial temperature range from -40 °C to +125 °C.

Feature Summary

• Eight-bit D-type edge-triggered flip-flop architecture with single-ended inputs and outputs
• High noise immunity and direct interface compatibility with TTL logic levels
• Partial power-down protection via dedicated I_OFF circuitry to prevent backflow current
• Robust electrostatic discharge protection exceeding 2000 V (HBM) and 1000 V (CDM)

Applications

• Parallel data storage and buffering in digital systems
• Shift register construction for serial-to-parallel conversion
• Timing synchronization and clock domain crossing interfaces

Procurement Notes

Verify the specific ordering code against official Nexperia documentation to ensure correct package variant and tape-and-reel specifications. Confirm that the DHVQFN-20 footprint matches your PCB design guidelines. Check for any recent Product Change Notifications regarding manufacturing site transfers or material updates before finalizing procurement orders.

Selection Notes

Select this component when an eight-bit parallel load capability is required within a compact surface-mount form factor. The wide 2 V to 5.5 V supply range allows flexibility in mixed-voltage environments. Ensure the 4.2 ns propagation delay meets your system timing requirements at the target operating voltage.

Part Context

This part belongs to the 74AHC family, which offers higher speed performance compared to standard LVC devices while maintaining CMOS low power dissipation characteristics. The BQ suffix indicates the DHVQFN-20 package type, distinguishing it from other pin-compatible variants like the SO20 or TSSOP20 packages available in the same logical family.

Replacement Considerations

Direct substitutes include the 74LVC273D,118 for SOIC packaging or other 74AHC273 variants from Nexperia with compatible pinouts. Verify electrical parameters such as output current and propagation delay match your design constraints before swapping packages.
