74HC3G07DC,125

Overview

The Nexperia 74HC3G07DC,125 is a triple buffer with open-drain outputs belonging to the high-speed CMOS (HC) logic family. It operates within a supply voltage range of 2 V to 6 V and supports a maximum operating temperature of +125 °C. The device is housed in an 8-pin Very Small Outline Plastic Package (VSSOP), designated as SOT765. It provides three independent non-inverting buffers with open-drain configurations, suitable for driving loads requiring level shifting or wired-OR connections.

Feature Summary

• Triple buffer configuration with open-drain outputs
• High-speed CMOS technology for low power dissipation
• Wide supply voltage operation from 2 V to 6 V
• Open-drain design enables level translation and wired-logic applications

Applications

• Level shifting between different voltage domains
• Wired-OR logic implementation
• Driving external loads such as LEDs or relays
• General-purpose buffering in digital circuits

Procurement Notes

Verify the exact part number suffix, specifically ',125', which indicates the specific tape and reel packaging format. Confirm that the open-drain output characteristic aligns with your circuit requirements, as standard push-pull outputs cannot be used for wired-OR configurations. Ensure the VSSOP-8 package dimensions match your PCB footprint constraints.

Selection Notes

Select this component when a triple buffer with open-drain outputs is required within the HC logic family. It is appropriate for designs needing operation across a wide voltage range up to 6 V. Consider alternative packages if higher pin counts or different thermal performance are needed, but ensure the logical function remains compatible with existing board layouts.

Part Context

This component is part of Nexperia's extensive portfolio of 74HC series logic devices. The '3G' designation indicates three gates per package, while '07' specifies the buffer function with open-drain outputs. The DC suffix denotes the VSSOP-8 surface-mount package. This series is widely used in consumer electronics and industrial control systems due to its compatibility with standard TTL and CMOS logic levels.

Replacement Considerations

Compatible substitutes include other 74HC3G07 variants from different manufacturers offering identical logical functions and pinouts. Verify that any replacement maintains the open-drain output specification and operates within the same 2 V to 6 V supply voltage range. Package compatibility must also be confirmed to ensure direct interchangeability.
