74ALVC32BQ,115

Overview

The Nexperia 74ALVC32BQ,115 is a quad 2-input OR gate from the ALVC logic family. It operates within a supply voltage range of 1.65 V to 3.6 V and supports an ambient temperature range of -40 °C to +125 °C. The device features Schmitt trigger action on all inputs for tolerance of slow rise and fall times. Propagation delay ranges from 1.0 ns to 3.2 ns depending on voltage. It includes IOFF circuitry for partial power-down applications and meets JESD8-7, JESD8-5, and JESD8C/JESD36 standards.

Feature Summary

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

Applications

• Partial power-down applications requiring IOFF functionality
• Systems interfacing with TTL level signals
• Logic circuits requiring tolerance for slow signal transitions

Procurement Notes

Verify that the specific ordering suffix ',115' corresponds to the DHVQFN14 package (SOT762-1) as documented in the official Nexperia datasheet. Confirm that the required operating temperature range aligns with the -40 °C to +125 °C specification provided for this part number. Ensure design compliance with the absolute maximum ratings to avoid permanent damage.

Selection Notes

Select this component when a quad 2-input OR gate is required with Schmitt trigger input characteristics. It is suitable for designs needing overvoltage tolerant inputs and partial power-down capabilities via IOFF circuitry. Verify that the DHVQFN14 package dimensions fit the PCB layout constraints and that the 1.65 V to 3.6 V supply voltage range matches the system requirements.

Part Context

This device belongs to the 74ALVC32 series of quad 2-input OR gates manufactured by Nexperia. The 'BQ' designation specifically identifies the DHVQFN14 plastic dual in-line compatible thermal enhanced very thin quad flat package variant. It is part of the broader ALVC logic family designed for low voltage and high-speed applications.

Replacement Considerations

Check for other 74ALVC32 variants with different package options such as SO14 or TSSOP14 if pin compatibility differs. Ensure any substitute maintains the same ALVC logic family specifications and DHVQFN14 footprint if board space is constrained.
