74ALVC02D,112

Overview

The Nexperia 74ALVC02D,112 is a quad 2-input NOR gate in the ALVC logic family. It operates within a supply voltage range of 1.65 V to 3.6 V and features Schmitt trigger inputs for slow signal tolerance. The device includes IOFF circuitry for partial power-down mode operation, preventing backflow current. It complies with JEDEC standards JESD8-7, JESD8-5, and JESD8C/JESD36. Latch-up performance exceeds 250 mA per JESD78 Class II.A. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Propagation delay ranges from 1.0 ns to 3.2 ns depending on voltage. Operating temperature spans -40 °C to +125 °C.

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 damaging backflow current.
• Overvoltage tolerant inputs allow direct interfacing with TTL levels and mixed voltage applications.

Applications

• Mixed 3.3 V and 5 V logic translation
• Partial power-down system designs
• Boolean logic control circuits

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the SO14 package (SOT108-1) as defined in the official datasheet. Confirm that the required operating temperature range meets the -40 °C to +125 °C specification. Ensure design compatibility with the 1.65 V to 3.6 V supply voltage limits. Check for any recent Product Change Notices regarding assembly or labeling updates.

Selection Notes

Select this component when low power dissipation and high-speed NOR logic are required in a single package. The ALVC technology offers a balance between speed and power consumption suitable for portable electronics. Verify input voltage compatibility if interfacing with higher voltage nodes, noting the 3.6 V input tolerance limit. Consider the SO14 package dimensions for PCB layout constraints.

Part Context

This part belongs to the Nexperia 74ALVC series, which utilizes Advanced Low-Voltage CMOS technology. The series is designed for applications requiring wide supply voltage ranges and direct interface capabilities with TTL logic levels. The 74ALVC02 specifically implements four independent 2-input NOR gates within a compact plastic small outline package.

Replacement Considerations

Nexperia offers alternative packages for the same logical function, including TSSOP14 (74ALVC02PW) and DHVQFN14 (74ALVC02BQ). These variants maintain identical electrical specifications but differ in physical footprint and thermal characteristics. Cross-manufacturer replacements require verification of pinout compatibility and voltage thresholds.
