MC74VHC1G09DFT1G-Q

Inverter Gates Overview

The MC74VHC1G09DFT1G-Q is a single-channel, 2-input AND gate with an open-drain output, fabricated using advanced high-speed silicon gate CMOS technology. It operates within a supply voltage range of 2.0 V to 5.5 V and supports input/output over-voltage tolerance up to 5.5 V regardless of the supply voltage. The device provides partial power-down protection via IOFF support and features inputs protected against voltages up to 5.5 V. It is designed for automotive applications, meeting AEC-Q100 qualification standards, and is available in the SC-88A (SOT-353) surface-mount package.

Inverter Gates Feature Summary

• Advanced high-speed CMOS logic providing performance comparable to Bipolar Schottky TTL while maintaining low power dissipation.
• Open-drain output structure allows interfacing between different voltage domains by setting the output switching level with external components.
• Input structures provide robust protection against over-voltage conditions up to 5.5 V, preventing device destruction during supply mismatches or hot insertion.
• IOFF feature enables partial power-down protection, minimizing leakage current when the device is powered off.

Inverter Gates Applications

• Automotive electronic systems requiring AEC-Q100 qualified logic components
• Level shifting interfaces between 5 V and 3 V digital circuits
• Battery backup circuitry where input protection during power loss is required
• Hot insertion scenarios involving voltage mismatch risks

Inverter Gates Procurement Notes

Verify that the ordering suffix includes the '-Q' designation to confirm AEC-Q100 automotive qualification status. Confirm the package type matches the required footprint, specifically the SC-88A variant for this part number. Ensure compliance with RoHS and Halogen-free material declarations as specified in the manufacturer's documentation before finalizing procurement specifications.

Inverter Gates Selection Notes

Select this component when an automotive-grade, single 2-input AND gate with open-drain output is required. It is suitable for designs needing interface capabilities between varying voltage levels, such as connecting 5 V logic to 3 V systems. Consider its propagation delay characteristics and supply voltage range to ensure compatibility with the target system's timing and power constraints.

Inverter Gates Part Context

This device belongs to the MC74VHC1G series of single-gate logic ICs from onsemi. It utilizes silicon gate CMOS technology to achieve high-speed operation similar to Bipolar Schottky TTL. The series is characterized by low internal power dissipation and wide operating temperature ranges, making it suitable for various commercial and industrial applications.

Inverter Gates Replacement Considerations

Check for MC74VHC1G09 variants without the '-Q' suffix if automotive qualification is not required. Verify pinout compatibility with alternative single 2-input AND gates in the SC-88A package. Ensure any substitute maintains the open-drain output configuration and over-voltage tolerance specifications.

Inverter Gates FAQ

What is the function of the open-drain output?

The open-drain output allows the device to interface 5 V circuits to circuits of any voltage between VCC and 7 V by using an external resistor and power supply to set the output switching level.

How does the device handle input over-voltage?

The input structures provide protection when voltages up to 5.5 V are applied, regardless of the supply voltage, helping prevent device destruction caused by supply voltage mismatches.

What is the purpose of the IOFF feature?

The IOFF feature supports partial power-down protection, allowing the device to minimize leakage current when powered down while inputs remain active.
