74ALVC32D,112

Overview

The 74ALVC32D,112 is a quad 2-input OR gate from the Nexperia 74ALVC series. It features Schmitt trigger action on all inputs for tolerance of slow rise and fall times. The device operates within a wide supply voltage range of 1.65 V to 3.6 V. It provides 3.6 V tolerant inputs and outputs, enabling direct interfacing with TTL levels in the 2.7 V to 3.6 V range. Key electrical characteristics include low power consumption and latch-up performance exceeding 250 mA per JESD 78 Class II standards.

Feature Summary

• Quad 2-input OR gate configuration
• Schmitt trigger input action for noise immunity
• 3.6 V tolerant I/O capabilities
• Direct interface compatibility with TTL logic levels

Applications

• Mixed voltage logic level translation between 3.3V and 5V systems
• Signal routing in digital control circuits
• Boolean logic implementation in embedded systems

Procurement Notes

Verify the specific suffix '112' against official Nexperia documentation to confirm tape and reel packaging specifications. Confirm current lifecycle status as ALVC products may undergo obsolescence notices. Ensure ESD handling protocols are followed during assembly due to CMOS construction. Cross-reference RoHS compliance data with the latest restricted substances declaration for regulatory adherence.

Selection Notes

Select this component when a quad OR gate function is required with 3.6V tolerance. The Schmitt trigger inputs make it suitable for noisy environments or signals with slow transition times. It serves as a bridge between different voltage domains, specifically interfacing lower voltage logic with 3.6V tolerant nodes. Consider package availability in SO-14 formats for PCB layout constraints.

Part Context

This part belongs to the 74ALVC (Advanced Low-Voltage CMOS) family, designed for high-speed operation with low power dissipation. The 74ALVC series supports supply voltages down to 1.65V, facilitating use in battery-powered applications. The 'D' indicates a SOIC-14 package, while '112' typically denotes the standard tape and reel packaging format used for automated surface-mount assembly processes.

Replacement Considerations

Official substitutes include other 74ALVC32 variants such as 74ALVC32BQ or 74ALVC32-Q100 for automotive grades. Verify pinout compatibility and electrical parameters before substitution. Check for updated datasheet revisions that may affect timing characteristics or package dimensions.
