74ALVC02BQ,115

Overview

The Nexperia 74ALVC02BQ,115 is a quad 2-input NOR gate in the ALVC logic family. It operates within a supply voltage range of 1.65 V to 3.6 V and supports an operating temperature from -40 °C to +125 °C. The device features Schmitt trigger inputs for noise immunity and IOFF circuitry for partial power-down protection. Propagation delay ranges from 1.0 ns to 5.4 ns depending on voltage. Input capacitance is typically 3.5 pF.

Feature Summary

• Schmitt trigger action on all inputs provides tolerance for slow rise and fall times.
• IOFF circuitry disables outputs during power-down to prevent damaging backflow current.
• Overvoltage tolerant inputs allow direct interface with TTL levels.

Applications

• Mixed 3.3 V and 5 V logic environments
• Partial power-down applications requiring input isolation
• Digital signal processing circuits

Procurement Notes

Verify the specific ordering suffix '115' matches the required tape and reel quantity. Confirm the DHVQFN14 package variant (SOT762-1) aligns with PCB footprint requirements. Ensure the selected component meets the specified -40 °C to +125 °C temperature range for the intended application environment.

Selection Notes

Select this component when low power dissipation and high noise immunity are required. The ALVC series offers faster switching speeds compared to standard LVC families. Verify that the 1.65 V to 3.6 V supply range covers the system's operational voltage needs. Consider the DHVQFN14 package for space-constrained designs.

Part Context

This part belongs to the Nexperia 74ALVC02 series of quad 2-input NOR gates. The BQ suffix indicates the DHVQFN14 leadless package. It is designed for low-voltage CMOS applications requiring robust input characteristics and partial power-down capabilities.

Replacement Considerations

Check for equivalent parts from other manufacturers offering the same ALVC logic family specifications. Ensure any substitute maintains the DHVQFN14 pinout and thermal pad configuration if soldered.
