74ALVC02PW,118

Overview

The Nexperia 74ALVC02PW,118 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 provides high latch-up performance exceeding 250 mA per JESD78 Class II.A and robust ESD protection (HBM > 2000 V, CDM > 1000 V). Propagation delay ranges from 1.0 ns to 3.2 ns depending on voltage. It is specified for ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Schmitt trigger action on all inputs ensures tolerance of slow rise and fall times.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent damaging backflow currents.
• High latch-up performance exceeds 250 mA according to JESD78 Class II.A standards.
• Robust electrostatic discharge protection with HBM ratings exceeding 2000 V and CDM ratings exceeding 1000 V.

Applications

• Mixed 3.3 V and 5 V logic interfacing
• Partial power-down applications requiring backflow prevention
• General-purpose digital logic processing

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74ALVC02 series is available in SO14, TSSOP14, and DHVQFN14 variants. Confirm that the selected component meets the necessary temperature range specifications for your application environment. Ensure compliance with JEDEC standards relevant to your target operating voltage. Check for any recent product change notices regarding assembly or labeling updates before finalizing procurement orders.

Selection Notes

Select this component when a quad 2-input NOR function is required with low power consumption and wide supply voltage compatibility. The ALVC family offers faster switching speeds compared to standard LVC devices. Consider the TSSOP14 package for space-constrained designs requiring surface mount technology. Verify input voltage levels against the TTL interface requirements if connecting to legacy logic families.

Part Context

This part belongs to the Nexperia 74ALVC02 series of quad 2-input NOR gates. The PW suffix indicates the TSSOP14 plastic thin shrink small outline package variant. It is part of the broader ALVC logic family designed for high-speed, low-power applications. Other package options include SO14 and DHVQFN14 for different board layout requirements.

Replacement Considerations

Direct pin-compatible replacements may include other manufacturers' 74ALVC02 equivalents. Verify electrical characteristics such as propagation delay and output drive current match the original specifications. Ensure the alternative component supports the same IOFF functionality if partial power-down is critical to the design.
