74HC3G07GD,125

Overview

The 74HC3G07GD,125 is a triple buffer with open-drain outputs 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 inputs with clamp diodes for interfacing voltages exceeding VCC. Propagation delays are specified at 95 ns maximum at 2.0 V and 25 ns maximum at 4.5 V.

Feature Summary

• Triple non-inverting buffers with open-drain outputs
• Inputs include clamp diodes for high-voltage interfacing
• High noise immunity and low power CMOS dissipation
• ESD protection exceeds 2000 V (HBM) and 1000 V (CDM)

Applications

• Implementing active-LOW wired-OR logic functions
• Implementing active-HIGH wired-AND logic functions
• Level shifting between different voltage domains

Procurement Notes

Verify the specific package designation GD corresponds to the SOT996-2 XSON8U variant listed in historical documentation. Confirm current production status as this package type was removed from the Rev 6 datasheet. Ensure compatibility with existing PCB footprints if substituting from other packages like DC or DP.

Selection Notes

Select this component when open-drain outputs are required for wired-logic configurations. Verify that the application can accommodate the necessary pull-up resistors to establish logic HIGH levels. Ensure the input voltage does not exceed the absolute maximum ratings without current limiting resistors.

Part Context

This part belongs to the 74HC series of high-speed Si-gate CMOS devices. It provides three independent buffers in a compact surface-mount package. The open-drain architecture distinguishes it from standard push-pull buffers, allowing for flexible output connection schemes in digital circuits.
