MC74VHC1G07DFT2G

Overview

The MC74VHC1G07DFT2G is a single non-inverting buffer 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 CMOS-level input thresholds. The device provides over-voltage tolerant inputs and outputs up to 5.5 V, regardless of the supply voltage level. It supports partial power down protection via IOFF functionality and delivers source/sink currents of 8 mA at 3.0 V. Typical propagation delay is 3.5 ns at 5 V. The component is available in SC-88A packages.

Feature Summary

• Single non-inverting buffer configuration with open-drain output structure
• Input and output structures tolerant to voltages up to 5.5 V independent of supply voltage
• Supports partial power down protection through IOFF feature
• Designed for operation across a wide supply voltage range from 2.0 V to 5.5 V

Applications

• Interfacing 5 V circuits to 3 V circuits
• Battery backup systems requiring voltage mismatch protection
• Hot insertion applications involving supply voltage mismatches

Procurement Notes

Verify the specific ordering suffix to confirm package type and shipping quantity. The DFT2G suffix indicates the SC-88A package with tape and reel shipping. Confirm RoHS compliance status and check for any automotive-specific requirements if using the -Q suffix variant. Ensure the application environment matches the specified operating temperature range and voltage limits defined in the datasheet maximum ratings.

Selection Notes

Select this component when a single-channel non-inverting buffer with open-drain output is required. It is suitable for applications needing interface between different voltage domains due to its over-voltage tolerance. Consider the SC-88A package size constraints and verify that the open-drain output architecture aligns with the pull-up resistor requirements of the target circuit design.

Part Context

This part belongs to the MC74VHC1G series of logic buffers. It shares functional similarities with the MC74VHC1GT07, which utilizes TTL-level input thresholds instead of CMOS-level thresholds. Both devices offer identical electrical characteristics regarding output drive and voltage tolerance but differ in input threshold specifications.
