74ALVC08BQ,115

Overview

The Nexperia 74ALVC08BQ,115 is a quad 2-input AND gate in the ALVC logic series. It operates within a supply voltage range of 1.65 V to 3.6 V and supports an ambient temperature range from -40 °C to +125 °C. The device features Schmitt-trigger inputs for noise tolerance and IOFF circuitry for partial power-down protection. It utilizes a DHVQFN14 package (SOT762-1) with dimensions of 2.5 x 3 x 0.85 mm. Propagation delay ranges from 1.0 ns to 3.7 ns depending on voltage and temperature.

Feature Summary

• Schmitt-trigger action at all inputs provides tolerance for slower input rise and fall times.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent damaging backflow current.
• Overvoltage tolerant inputs allow direct interface with TTL levels without external resistors.

Applications

• Partial power-down applications requiring backflow current prevention
• Mixed voltage systems interfacing 3.3 V or 5 V devices with lower voltage logic
• Digital signal processing circuits requiring noise immunity

Selection Notes

Select this component when low power dissipation and high-speed operation are required in compact designs. The DHVQFN14 package offers thermal enhancement suitable for dense PCB layouts. Ensure the application voltage remains within the 1.65 V to 3.6 V range to maintain specified performance characteristics.

Part Context

This part belongs to the Nexperia 74ALVC08 family of quad 2-input AND gates. It shares functional specifications with other packages like SO14 and TSSOP14 but differs in physical footprint. The BQ suffix specifically denotes the DHVQFN14 variant, distinguishing it from standard plastic small outline packages.

Replacement Considerations

Direct substitutes include 74ALVC08D (SO14) and 74ALVC08PW (TSSOP14). These alternatives share identical electrical specifications but require different PCB footprints due to distinct package types.
