74HCT1G32GV,125

Overview

The Nexperia 74HCT1G32GV,125 is a single 2-input OR gate in the 74HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-level input compatibility. The device utilizes a SC-74A (SOT753) surface-mount package with five leads. Static characteristics specify an input leakage current maximum of 1.0 µA at 5.5 V and a supply current maximum of 20 µA. Dynamic performance includes a propagation delay of up to 27 ns at 4.5 V with a 50 pF load.

Feature Summary

• TTL-compatible input levels for direct interfacing with standard logic systems
• High noise immunity and symmetrical output impedance
• ESD protection exceeding 2000 V via Human Body Model standards

Applications

• General-purpose digital logic signal processing
• Signal routing and selection circuits
• Interface modules between TTL and CMOS logic domains

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm the exact package variant and marking code. Confirm RoHS compliance status and REACH registration requirements prior to integration. Ensure design specifications align with the absolute maximum ratings defined in the official product data sheet to prevent permanent damage during operation.

Selection Notes

Select this component when TTL-level inputs are required within a 5 V system architecture. The HCT series provides higher noise margins compared to HC variants at standard operating voltages. Verify that the SC-74A package dimensions fit the target PCB footprint constraints and thermal dissipation requirements for the intended application environment.

Part Context

This part belongs to the 74HCT1G32 family of single 2-input OR gates manufactured by Nexperia. It shares functional similarities with the 74HC1G32 but differs in input threshold specifications to support TTL logic levels. The GV suffix indicates the SC-74A plastic surface-mounted package configuration.
