MC74VHCT32AD

Inverter Gates Overview

The MC74VHCT32AD is a quad 2-input OR gate manufactured by onsemi, belonging to the VHCT logic series. It utilizes advanced high-speed CMOS technology with silicon gate fabrication. The device operates within a supply voltage range of 2.0 V to 5.5 V and features propagation delays of 5.3 ns. It supports an operating temperature range from -55°C to +125°C and includes power-down protection on inputs.

Inverter Gates Feature Summary

• Advanced high-speed CMOS technology providing performance comparable to equivalent bipolar Schottky TTL while maintaining low power dissipation.
• Inputs tolerate voltages up to 7 V, enabling direct interfacing between 5 V systems and 3 V systems.
• Includes power-down protection on inputs to prevent excessive current draw during power-off states.

Inverter Gates Applications

• High-speed digital signal processing circuits
• Memory address decoding logic
• Interface bridging between 5 V and 3 V logic domains

Inverter Gates Procurement Notes

Verify the specific suffix (e.g., ADTR2G) for tape-and-reel packaging requirements. Confirm RoHS compliance status and AEC-Q100 qualification if automotive application is intended. Ensure the ordering part number matches the exact package type and temperature grade required for the design.

Inverter Gates Selection Notes

Select this component when high-speed OR logic is required in mixed-voltage environments. The VHCT series offers CMOS low power with TTL-compatible speeds. Verify that the 7 V input tolerance meets the system's maximum output voltage levels to ensure reliable operation across the full temperature range.

Inverter Gates Part Context

This component is part of the MC74VHCT32A family, which provides quad 2-input OR gates. The VHCT series is designed to bridge the gap between standard CMOS and TTL logic families, offering improved speed without sacrificing the low power advantages of CMOS technology.

Inverter Gates Replacement Considerations

Check for pin-compatible alternatives such as the MC74VHC32A or MC74VHC32ADTR2G. Verify that substitute parts maintain the same 2.0 V to 5.5 V operating range and 5.3 ns propagation delay specifications.
