MC74VHC1G03DTT1G

Inverter Gates Overview

The MC74VHC1G03DTT1G 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 supports partial power down protection via IOFF and provides source/sink currents of 8 mA at 3.0 V. It is available in SC-88A and SC-74A packages, with a typical propagation delay of 3.5 ns at 5 V.

Inverter Gates Feature Summary

• Single 2-input NOR logic function with open drain output configuration

Inverter Gates Procurement Notes

Verify the specific ordering suffix to confirm package type and shipping quantity. Confirm RoHS compliance status as required for your assembly process. Check current availability as product lifecycles may change. Ensure the selected variant matches your PCB footprint requirements for SC-88A or SC-74A packages.

Inverter Gates Selection Notes

Select this component when a compact single-channel NOR gate with open drain capability is needed. Consider the MC74VHC1GT03 variant if TTL-level input thresholds are required instead of CMOS levels. Evaluate the operating temperature range and supply voltage constraints against your system design specifications before finalizing the part number.

Inverter Gates Part Context

This component belongs to the MC74VHC1G series of high-speed CMOS logic devices from onsemi. The series utilizes silicon gate CMOS technology to provide low power consumption and high noise immunity. These devices are designed for portable and battery-operated applications due to their wide supply voltage range and low quiescent current characteristics.
