74ALVC02D,112

Overview

The 74ALVC02D,112 is a quad 2-input NOR gate manufactured by Nexperia. It operates within a supply voltage range of 1.65 V to 3.6 V and features Schmitt trigger action on all inputs for tolerance of slow rise and fall times. The device includes IOFF circuitry to prevent damaging backflow current during partial power-down applications. It complies with JEDEC standards JESD8-7, JESD8-5, and JESD8C/JESD36. The typical propagation delay is 2.2 ns at 3.3 V, with a maximum of 3.2 ns across the extended temperature range. Input leakage current is typically ±0.1 μA.

Feature Summary

• Schmitt trigger action on all inputs provides tolerance for slow signal transitions.
• 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 protection against backflow current
• Logic circuits interfacing with TTL level signals
• Systems requiring tolerance for slow input rise and fall times

Procurement Notes

Verify the manufacturer designation as Nexperia, consistent with the datasheet source, despite potential distributor listings under NXP USA Inc. Confirm the package type is SO14 (SOT108-1) and check for RoHS compliance status. Ensure the ordering suffix matches the specific package variant required for the design.

Selection Notes

Select this component when a quad 2-input NOR function is needed with Schmitt trigger inputs for noise immunity. It is suitable for designs operating between 1.65 V and 3.6 V that require direct TTL interfacing. The inclusion of IOFF circuitry makes it appropriate for systems managing partial power states to avoid backflow issues.

Part Context

This part belongs to the 74ALVC logic family, characterized by low power consumption and high-speed operation. The 'D' suffix indicates the SO14 plastic small outline package with a 3.9 mm body width. The '112' suffix denotes the standard reel packaging configuration used by Nexperia for distribution.

Replacement Considerations

Check for other packages in the same family such as 74ALVC02PW or 74ALVC02BQ if different form factors are required. Verify pin compatibility before substituting with generic ALVC NOR gates from other manufacturers.
