MC74VHC1G07DFT2

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 utilizes CMOS technology for low power dissipation. The device features inputs/outputs over-voltage tolerant up to 5.5 V, supporting interface between 5 V and 3 V circuits. It provides partial power down protection via IOFF support and can source/sink 8 mA at 3.0 V. Typical propagation delay is 3.5 ns at 5 V. It is available in SC-88A packages.

Feature Summary

• Single non-inverting buffer with open drain output structure
• Inputs and outputs are over-voltage tolerant up to 5.5 V regardless of supply voltage
• Supports partial power down protection through IOFF feature
• Capable of sourcing and sinking 8 mA at 3.0 V

Applications

• Interfacing 5 V circuits to 3 V circuits
• Battery backup systems requiring input/output voltage mismatch protection
• Hot insertion applications
• Automotive applications requiring AEC-Q100 qualification (suffix -Q)

Procurement Notes

Verify the specific ordering suffix to confirm package type and shipping quantity. The DFT2G suffix indicates the SC-88A package with a tape and reel quantity of 3000 units. Ensure the required application does not demand the automotive qualified -Q variant if standard commercial grade is sufficient. Confirm RoHS compliance and Pb-free status as stated in the datasheet specifications.

Selection Notes

Select this component when a single-channel non-inverting buffer with open drain capability is required. It is suitable for designs needing high-speed operation with typical propagation delays around 3.5 ns at 5 V. Choose this part if the design requires over-voltage tolerant I/Os for interfacing different voltage domains or protecting against hot insertion events. Consider the -Q suffix version if automotive PPAP capabilities are necessary.

Part Context

This device belongs to the MC74VHC1G series of advanced high-speed CMOS logic devices from onsemi. It is functionally similar to bipolar Schottky TTL but maintains CMOS low power dissipation characteristics. The series includes variants like the MC74VHC1GT07 which features TTL-level input thresholds instead of CMOS-level thresholds found in the MC74VHC1G07.

Replacement Considerations

MC74VHC1GT07DFT2G: Functionally identical buffer but with TTL-level input thresholds instead of CMOS-level thresholds.

FAQ

What is the difference between MC74VHC1G07 and MC74VHC1GT07?

The MC74VHC1G07 has CMOS-level input thresholds, while the MC74VHC1GT07 has TTL-level input thresholds. Both share the same open drain output structure and electrical characteristics otherwise.

How does the IOFF feature benefit the circuit?

The IOFF feature supports partial power down protection, preventing excessive current flow from the outputs when the device is powered down but still connected to active signal lines.
