74ALVC32D,118

Overview

The Nexperia 74ALVC32D,118 is a quad 2-input OR gate in the 74ALVC logic family. It operates on a supply voltage range of 1.65 V to 3.6 V and features Schmitt trigger inputs for tolerance to slow rise and fall times. The device includes IOFF circuitry for partial power-down mode operation, preventing backflow current. It supports an operating temperature range from -40 °C to +125 °C and complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36.

Feature Summary

• Schmitt trigger action on all inputs provides tolerance to slow signal transitions.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent damaging backflow currents.
• Overvoltage tolerant inputs allow direct interfacing with TTL levels without external resistors.

Applications

• Partial power-down applications requiring protection against backflow current
• Digital logic circuits utilizing OR gate functions
• Mixed voltage environments with TTL level interfacing

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base part number covers multiple options. Confirm that the D suffix corresponds to the SO14 plastic small outline package (SOT108-1) with a body width of 3.9 mm. Ensure the component meets the specified temperature range requirements for your application environment before finalizing procurement.

Selection Notes

Select this component when a quad 2-input OR gate is needed within the 74ALVC family. It is suitable for designs requiring Schmitt trigger inputs to handle slow signal edges. Consider the IOFF feature if the system utilizes partial power-down modes to minimize leakage and protect downstream components from backflow currents during inactive states.

Part Context

This component belongs to the 74ALVC series, which utilizes Advanced Low-Voltage CMOS technology. The 'D' suffix indicates the SO14 package variant. The 74ALVC32 serves as a fundamental building block for Boolean algebra operations in digital circuits, offering low power dissipation and high-speed performance compared to standard CMOS families.

Replacement Considerations

Check for alternative packages such as TSSOP14 (PW) or DHVQFN14 (BQ) if different form factors are required. Verify compatibility with other manufacturers' 74ALVC32 equivalents to ensure pinout and electrical specifications match the design requirements.
