MC74VHC1G07DFT1G-L22038

Overview

The MC74VHC1G07DFT1G-L22038 is a single non-inverting buffer with an open drain output, fabricated using advanced silicon gate CMOS technology. It operates within a supply voltage range of 2.0 V to 5.5 V and features inputs/outputs over-voltage tolerant up to 5.5 V. The device provides high-speed operation with a typical propagation delay of 3.5 ns at 5 V and supports partial power down protection via IOFF. It is available in the SC-88A package.

Feature Summary

• Single non-inverting buffer with open drain output for flexible level shifting
• Inputs and outputs are over-voltage tolerant up to 5.5 V regardless of supply voltage
• Supports partial power down protection through IOFF functionality
• High-speed operation with low internal power dissipation

Applications

• Interfacing 5 V circuits to 3 V circuits
• Battery backup systems requiring voltage mismatch protection
• Hot insertion applications
• General purpose buffering in portable electronics

Procurement Notes

Verify the specific ordering suffix DFT1G corresponds to the SC-88A package with V7 Q2 pin orientation and tape & reel shipping configuration. Confirm that the L22038 suffix aligns with the manufacturer's current marking and packaging specifications. Ensure compliance requirements such as RoHS and Pb-free status match project standards before procurement.

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 input and output pins while operating between 2.0 V and 5.5 V. Consider the SC-88A footprint constraints and the specific drive strength of 8 mA at 3.0 V for load matching.

Part Context

This part belongs to the MC74VHC1G series of high-speed CMOS logic devices from onsemi. It shares functional similarities with the MC74VHC1G05 (inverter) and MC74VHC1G07 (buffer), differing primarily in logic function and output structure. The VHC family offers performance comparable to Bipolar Schottky TTL with lower power consumption.

Replacement Considerations

Direct replacements include other MC74VHC1G07 variants with different packages or suffixes, such as MC74VHC1G07DBVT1G for SC-74A packaging. Verify pinout compatibility and electrical characteristics against the original design requirements when substituting.
