MC74VHC1G03DFT2G

Inverter Gates Overview

The MC74VHC1G03DFT2G is a single 2-input NOR gate with an open drain output manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 5.5 V and features inputs/outputs over-voltage tolerant up to 5.5 V. The device provides partial power down protection via IOFF support and can source or sink 8 mA at 3.0 V. It is available in SC-88A packages.

Inverter Gates Feature Summary

• Features over-voltage tolerant inputs and outputs capable of handling voltages up to 5.5 V regardless of the supply voltage, facilitating safe interfacing between 5 V and 3 V circuits.
• Supports partial power down operations through IOFF functionality, preventing excessive current draw when the device is powered off but connected to active signal lines.
• Provides robust protection against supply voltage mismatches, battery backup scenarios, and hot insertion events through specialized input and output structures.

Inverter Gates Applications

• Interfacing 5 V logic circuits to 3 V logic circuits
• Partial power down protection in portable electronic devices
• Hot insertion applications requiring voltage mismatch tolerance

Inverter Gates Procurement Notes

Verify that the ordering suffix matches the required package type, as the DFT2G designation specifically indicates the SC-88A package configuration. Confirm compliance requirements such as RoHS status and Pb-free specifications directly from the manufacturer's documentation before finalizing procurement decisions for production integration.

Inverter Gates Selection Notes

Select this component when a compact 2-input NOR gate with open drain output is required for low-voltage digital logic applications. Consider its over-voltage tolerance if operating in mixed-voltage environments where signal levels may exceed the supply rail. Ensure the open drain nature aligns with the pull-up requirements of the target circuit design.

Inverter Gates Part Context

This part belongs to the MC74VHC1G series of single-gate logic ICs designed for high-speed CMOS applications. The VHC series offers performance comparable to standard TTL speeds while maintaining low power consumption typical of modern CMOS technology. The specific model integrates a NOR function into a minimal footprint suitable for space-constrained PCB layouts.
