74HCT2G32GD,125

Overview

The 74HCT2G32GD,125 is a dual 2-input OR gate from the Nexperia 74HCT series. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of -40 °C to +125 °C. The device features overvoltage tolerant inputs up to 5.5 V, allowing use as a translator in mixed-voltage environments. It provides CMOS low power dissipation, high noise immunity, and symmetrical output impedance with balanced propagation delays.

Feature Summary

• Dual 2-input OR logic function
• Overvoltage tolerant inputs for mixed-voltage translation
• High noise immunity and low power dissipation

Applications

• Mixed-voltage signal translation
• Digital logic circuits requiring OR functionality
• Portable battery-powered equipment

Procurement Notes

Verify the specific suffix GD corresponds to the SC-74A package when ordering. Confirm RoHS compliance and halogen-free status against current Nexperia environmental declarations. Ensure the design accounts for the specified 4.5 V to 5.5 V supply voltage range and thermal characteristics for the intended operating environment.

Selection Notes

Select this component for applications requiring dual OR gates in a compact surface-mount package. It is suitable where TTL-level input compatibility is needed at 5 V operation. Consider the SC-74A footprint constraints and verify that the overvoltage tolerance meets system interface requirements without external protection.

Part Context

This part belongs to the Nexperia 74HCT family of single-function gates. It shares logical functionality with other variants like the 74HCT2G32DC but differs in packaging. The HCT series ensures compatibility with standard TTL logic levels while maintaining CMOS performance characteristics.

Replacement Considerations

Direct substitutes include 74HCT2G32DC,125 (VSSOP-8) and 74HCT2G32DP,125 (TSSOP-8). Verify pinout compatibility and package dimensions before substitution.
