74HC2G32GD,125

Overview

The 74HC2G32GD,125 is a dual 2-input OR gate manufactured by Nexperia. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device features CMOS input levels and includes clamp diodes on inputs for interfacing with voltages exceeding VCC. Static characteristics specify a maximum low-level output voltage of 0.4 V at 5.2 mA (VCC=6.0 V) and a maximum high-level output voltage drop of 0.8 V at the same current. Dynamic performance under VCC=6.0 V conditions indicates a typical propagation delay of 7.0 ns and a transition time of 5 ns.

Feature Summary

• Dual 2-input OR logic function in a compact package
• Wide operating supply voltage range from 2.0 V to 6.0 V
• Input clamp diodes allow safe interfacing above VCC
• High noise immunity and latch-up protection exceeding 100 mA

Applications

• Digital signal processing circuits requiring logical OR operations
• Interface circuits connecting inputs to voltages higher than the supply rail
• Battery-powered devices utilizing wide voltage tolerance
• General-purpose logic applications in consumer electronics

Procurement Notes

Verify the specific ordering suffix GD corresponds to the XSON8U or XSON8 package variant as indicated in historical revision notes. Confirm that the component meets the required temperature grade (-40 °C to +125 °C) for your application environment. Ensure design compatibility with the specified static and dynamic electrical limits provided in the official datasheet before finalizing procurement.

Selection Notes

Select this component when a dual OR gate configuration is required in a small footprint. The HC series offers CMOS input levels suitable for standard digital logic families. Consider the 74HCT2G32 variant if TTL input levels are necessary instead. Verify that the package type matches the PCB layout constraints and that the thermal dissipation capabilities are sufficient for the intended operating conditions.

Part Context

This part belongs to the Nexperia 74HC/HCT2Gxx family of dual logic gates designed for space-constrained applications. The 'GD' suffix typically denotes an XSON package, which was previously referenced as XSON8U in earlier documentation revisions. This family provides a cost-effective solution for implementing basic Boolean functions in portable and industrial electronic systems.

Replacement Considerations

The datasheet revision history explicitly states that type numbers 74HC2G32GD and 74HCT2G32GD were removed from the product specification. Consequently, no direct replacement part numbers are listed in the current official documentation.
