74ALVC02D,118

Overview

The Nexperia 74ALVC02D,118 is a quad 2-input NOR gate in an SO14 package. It operates within a supply voltage range of 1.65 V to 3.6 V and supports temperatures from -40 °C to +125 °C. The device features Schmitt trigger inputs for slow signal tolerance and IOFF circuitry for partial power-down protection. Propagation delay ranges from 1.0 ns to 3.2 ns depending on voltage. Static characteristics include low leakage currents and compliance with JEDEC standards.

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 backflow current.
• Overvoltage tolerant inputs allow direct interface with TTL levels.

Applications

• Partial power-down applications requiring IOFF functionality
• Mixed voltage logic interfacing
• General purpose digital logic processing

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74ALVC02 family includes TSSOP and DHVQFN variants. Confirm temperature grade specifications align with system requirements. Ensure design accounts for absolute maximum ratings to avoid permanent damage. Check for recent product change notices regarding marking or assembly updates.

Selection Notes

Select this component when low propagation delay and high noise immunity via Schmitt triggers are required. The IOFF feature makes it suitable for systems with partial power states. Verify that the 1.65 V to 3.6 V operating range covers all system voltage rails. Consider thermal derating if operating near the upper temperature limit.

Part Context

This part belongs to the Nexperia 74ALVC02 family of quad 2-input NOR gates. It is manufactured by Nexperia USA Inc. and complies with JEDEC standards JESD8-7, JESD8-5, and JESD8C/JESD36. The device offers ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Replacement Considerations

Check for equivalent parts in the 74LVC or 74AHC families if voltage compatibility differs. Verify pinout and package dimensions match the PCB footprint before substitution.
