74AHCT2G32DP,125

Overview

The Nexperia 74AHCT2G32DP,125 is a dual 2-input OR gate in the HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL input levels. The device features overvoltage tolerant inputs up to 5.5 V, enabling use as translators in mixed voltage environments. It provides CMOS low power dissipation, symmetrical output impedance, and high noise immunity. The component is specified for ambient temperatures from -40 °C to +125 °C and includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Dual 2-input OR gate functionality with TTL input switching levels.
• Overvoltage tolerant inputs allowing operation in mixed voltage environments.
• High noise immunity and balanced propagation delays.
• Robust latch-up performance exceeding 100 mA per JESD 78 Class II Level A.

Applications

• Mixed voltage signal translation between different logic families.
• General purpose digital logic applications requiring OR functionality.
• Industrial control systems operating across wide temperature ranges.

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the HCT logic family aligns with system voltage requirements. Ensure environmental specifications meet operational needs. Check for any recent product status changes or obsolescence notices via official channels before finalizing procurement decisions.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS performance characteristics. The HCT series ensures compatibility with standard TTL logic outputs while offering improved speed and lower power consumption compared to older HC variants. Consider the TSSOP8 package constraints for PCB layout and thermal management during design integration.

Part Context

This part belongs to the Nexperia 74AHC/AHCT2G32 series of dual 2-input OR gates. It shares functional similarities with the 74AHC2G32 but utilizes HCT input levels for broader compatibility. The DP suffix indicates the TSSOP8 plastic thin shrink small outline package, distinguishing it from other package options like VSSOP8 available within the same logical family.

Replacement Considerations

Direct substitutes include the 74AHC2G32DP,125 for CMOS input levels or the 74AHCT2G32DC,125 for alternative packaging. Verify pinout compatibility and electrical parameters before substitution. Cross-reference with other manufacturers' equivalents only if datasheet specifications match exactly.

FAQ
