74HCT1G02GV,125

Overview

The Nexperia 74HCT1G02GV,125 is a single 2-input NOR gate in the 74HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input levels. The device includes input clamp diodes for interfacing with voltages exceeding VCC. It provides ESD protection exceeding 2000 V (HBM) and complies with JEDEC standards JESD8C and JESD7A. Static characteristics include an input leakage current maximum of 1 μA at VCC = 5.5 V and a supply current maximum of 10 μA under specified conditions.

Feature Summary

• TTL-compatible input levels ensure direct interface with standard digital logic systems.
• Integrated input clamp diodes allow safe operation when interfacing with voltages higher than the supply rail using current limiting resistors.
• High noise immunity and balanced propagation delays support reliable signal integrity in mixed-signal environments.

Applications

• General-purpose digital logic circuits requiring NOR functionality
• Signal processing interfaces utilizing TTL-level inputs
• Mixed-voltage system designs leveraging input clamp diode capabilities

Selection Notes

Select this component when a single 2-input NOR gate with TTL-compatible inputs is required. The 74HCT series ensures compatibility with standard 5V logic families while offering low power dissipation. Ensure the application environment remains within the specified -40 °C to +125 °C temperature range and that supply voltage constraints between 4.5 V and 5.5 V are strictly maintained for optimal performance.

Part Context

This part belongs to the Nexperia 74HCT1Gxx series of single-function gates. It shares the same logical function as other variants like the 74HCT1G02GW but utilizes the SC-74A (SOT753) package instead of TSSOP. This series is designed for compact surface-mount applications where space efficiency is critical alongside standard logic performance.

Replacement Considerations

Direct pin-to-pin replacements within the same package include the 74HC1G02GV,125, though it requires CMOS-level inputs rather than TTL. Other functional equivalents in different packages such as the 74HCT1G02GW or 74HCT1G02GZ may be considered if board layout allows for package adaptation.
