MC74VHC1G02DFT1G-Q

Inverter Gates Overview

The MC74VHC1G02DFT1G-Q is a single 2-input NOR gate manufactured by onsemi using advanced high-speed CMOS technology. It operates within a supply voltage range of 2.0 V to 5.5 V and supports an operating temperature range from -55 °C to +125 °C. The device features inputs/outputs over-voltage tolerant up to 5.5 V, allowing interface between 5 V and 3 V circuits. It provides source/sink currents of 8 mA at 3.0 V and includes IOFF support for partial power-down protection. The typical propagation delay is 3.5 ns at 5 V. It is packaged in the SC-88A (SOT-353) format.

Inverter Gates Feature Summary

• Advanced high-speed CMOS logic with CMOS-level input thresholds
• Over-voltage tolerant inputs and outputs up to 5.5 V
• IOFF feature enables partial power-down protection
• -Q suffix indicates AEC-Q100 qualification and PPAP capability

Inverter Gates Applications

• Automotive electronic systems requiring unique site control
• Interfacing 5 V circuits to 3 V circuits
• Battery backup circuitry applications
• Hot insertion protection scenarios

Inverter Gates Procurement Notes

Verify that the ordering suffix matches the specific package variant required, as the datasheet lists multiple shipping options for this device family. Confirm the presence of the -Q suffix if automotive qualification and PPAP capability are mandatory for the application. Ensure compliance with RoHS standards and check for Pb-Free or Halogen-Free/BFR-Free status during procurement validation.

Inverter Gates Selection Notes

Select this component when a compact single-channel NOR gate is needed for high-speed digital logic. The choice depends on the requirement for over-voltage tolerance to handle mixed-voltage interfaces without external protection. Consider the SC-88A footprint constraints and the need for wide operating temperature ranges suitable for harsh environments.

Inverter Gates Part Context

This part belongs to the MC74VHC1G series of single-gate logic devices. It shares functional similarities with the MC74VHC1GT02 but utilizes CMOS-level input thresholds rather than TTL-level thresholds. The series is designed for minimal footprint integration while maintaining robust electrical characteristics and high noise immunity.

Inverter Gates Replacement Considerations

Direct substitutes include other single 2-input NOR gates in similar small packages. Verify pinout compatibility and electrical specifications such as supply voltage range and output drive current before substitution.
