74AHC1G02GV/C4H

Overview

The Nexperia USA Inc. 74AHC1G02GV/C4H is a single 2-input NOR gate in the 74AHC series, housed in a SC-74A (SOT753) plastic surface-mounted package with 5 leads. It operates on a supply voltage range of 2.0 V to 5.5 V and supports an ambient temperature from -40 °C to +125 °C. The device features overvoltage tolerant inputs up to 5.5 V, CMOS low power dissipation, and symmetrical output impedance. Static characteristics include a maximum input leakage current of 2.0 µA at -40 °C to +125 °C and a maximum supply current of 40 µA. Dynamic performance specifies a typical propagation delay of 6.3 ns at 3.3 V with 50 pF load, and 4.6 ns at 5.0 V with 50 pF load.

Feature Summary

• Single 2-input NOR logic function
• Overvoltage tolerant inputs compatible with mixed voltage environments
• CMOS technology ensuring low static and dynamic power consumption
• ESD protection exceeding 2000 V HBM and 1000 V CDM

Applications

• Mixed voltage signal translation
• Portable battery-powered equipment
• Consumer electronics logic control

Procurement Notes

Verify the specific ordering suffix matches the required package variant, as the GV designation corresponds to the SC-74A (SOT753) outline. Confirm that the C4H suffix aligns with your manufacturing requirements, noting that standard datasheets primarily reference the base type number. Ensure compliance with RoHS3 specifications and check for any recent Product Change Notifications regarding marking or assembly updates before finalizing procurement.

Selection Notes

Select this component when a compact 2-input NOR gate is needed for low-power applications operating between 2.0 V and 5.5 V. The SC-74A package offers a small footprint suitable for space-constrained designs. Choose this part over the AHCT variant if CMOS input levels are preferred over TTL levels. Verify that the 8 mA output drive capability meets the load requirements of the downstream circuitry.

Part Context

This device belongs to the 74AHC family of high-speed Si-gate CMOS logic devices. It shares functional similarities with other single-gate components like the 74AHC1G00 (NAND) and 74AHC1G04 (Inverter). The GV package variant provides a thin shrink small outline form factor, distinct from the TSSOP5 (GW) and XSON5 (GZ) options available within the same logical family.

Replacement Considerations

Direct substitutes include the 74AHC1G02GW (TSSOP5 package) and 74AHC1G02GZ (XSON5 package) from Nexperia, which share identical electrical characteristics but differ in physical dimensions. Cross-brand equivalents must be verified against the 2.0 V to 5.5 V supply range and SC-74A pinout compatibility.
