74ALVC32D-Q100J

Overview

The Nexperia 74ALVC32D-Q100J is a quad 2-input OR gate qualified to AEC-Q100 Grade 1 standards for automotive applications. 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 slow signal tolerance and IOFF circuitry for partial power-down protection. Propagation delay ranges from 1.0 ns to 5.4 ns depending on voltage, with a typical power dissipation capacitance of 25 pF per gate.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1
• IOFF circuitry prevents damaging backflow current during power-down
• Schmitt trigger action ensures tolerance for slow rise and fall times
• Overvoltage tolerant inputs allow direct interface with TTL levels

Applications

• Automotive engine control units
• Body control modules
• Transmission control units

Procurement Notes

Verify the specific package variant against the required footprint, as the D suffix denotes the SO14 (SOT108-1) package. Confirm that the design accommodates the specified thermal derating curves for the SO14 package above 100 °C. Ensure input transition rates comply with the recommended operating conditions for the target supply voltage to maintain signal integrity.

Selection Notes

Select this component when a quad OR gate is required in mixed-voltage environments or where partial power-down isolation is necessary. The ALVC series offers low power consumption while maintaining compatibility with standard logic levels. Verify that the propagation delay specifications meet the timing requirements of the system at the intended operating voltage.

Part Context

This part belongs to the Nexperia 74ALVC32-Q100 family of automotive-grade logic gates. The family includes variants such as the PW (TSSOP14) and BQ (DHVQFN14) packages. All variants share identical electrical characteristics and functional descriptions, differing only in physical packaging dimensions and pin configurations.

Replacement Considerations

Direct substitutes include other AEC-Q100 Grade 1 quad 2-input OR gates from manufacturers like Texas Instruments or NXP, provided they match the 14-pin SOIC footprint and electrical parameters.
