MC74VHC1G07DFT1G

Overview

The MC74VHC1G07DFT1G 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 utilizes CMOS-level input thresholds. The device features over-voltage tolerant inputs and outputs up to 5.5 V, allowing interface between 5 V and 3 V circuits. It supports partial power-down protection via IOFF and provides source/sink currents of 8 mA at 3.0 V. Typical propagation delay is 3.5 ns at 5 V. The component is housed in an SC-88A package.

Feature Summary

• Single non-inverting buffer configuration with open-drain output structure
• Inputs and outputs tolerate voltages up to 5.5 V regardless of supply voltage
• Supports partial power-down protection through IOFF functionality
• CMOS-level input thresholds designed for 2.0 V to 5.5 V operation

Applications

• Interfacing 5 V logic circuits to 3 V logic circuits
• Battery backup systems requiring protection against supply/input mismatch
• Hot insertion applications involving voltage level translation
• General purpose buffering where open-drain output is required

Procurement Notes

Verify the specific ordering suffix DFT1G corresponds to the SC-88A package and standard shipping configuration. Confirm that the device meets RoHS compliance requirements as stated in the datasheet. Ensure the application environment stays within the recommended operating temperature range of -55°C to +125°C. Check for any site-specific control change requirements if automotive qualification is needed, which would require the -Q suffix instead.

Selection Notes

Select this component when a single-channel non-inverting buffer with open-drain capability is required. It is suitable for designs needing over-voltage tolerance on both inputs and outputs without external resistors. Consider the SC-88A package size for space-constrained layouts. Verify that the load capacitance and supply voltage align with the specified propagation delay characteristics.

Part Context

This part belongs to the MC74VHC1G07 family of single buffers. It shares functional similarities with the MC74VHC1GT07, which differs only in having TTL-level input thresholds instead of CMOS-level. Both devices offer identical electrical performance regarding drive strength and over-voltage tolerance but are distinguished by their input threshold specifications.

Replacement Considerations

MC74VHC1GT07DFT1G serves as a direct functional substitute if TTL-level input thresholds are acceptable or preferred over the CMOS-level thresholds of the MC74VHC1G07.
