MC74VHC1G50DFT1G-L22038

Overview

The MC74VHC1G50DFT1G is a single-channel non-inverting buffer manufactured by onsemi using advanced high-speed 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, enabling safe interfacing between 5 V and 3 V circuits. The device provides push-pull outputs capable of sourcing and sinking 8 mA at 3.0 V. It includes IOFF support for partial power-down protection and offers ESD withstand voltages of 2000 V (HBM) and 1000 V (CDM. Packaged in the SC-88A (SOT-353) format.

Feature Summary

• Advanced high-speed CMOS construction with low input capacitance
• Over-voltage tolerant I/O structures allowing 5 V signal interfacing with 3 V supplies
• IOFF feature supports partial power-down mode to minimize leakage current
• Robust ESD protection meeting HBM and CDM standards

Applications

• Interface bridging between 5 V and 3 V logic families
• Partial power-down protection in battery backup systems
• Hot insertion circuit protection
• Signal buffering in compact mobile devices

Procurement Notes

Verify the specific ordering suffix 'L22038' against official manufacturer documentation, as standard datasheets list suffixes such as DFT1G or DFT2G. Confirm package orientation and marking details directly from the latest revision of the MC74VHC1G50/D datasheet to ensure compatibility with design requirements.

Selection Notes

Select this component when a single-channel non-inverting buffer is required for space-constrained designs utilizing the SC-88A package. Ensure the application voltage remains within the 2.0 V to 5.5 V range. Consider the MC74VHC1GT50 variant if TTL-level input thresholds are necessary instead of CMOS-level thresholds.

Part Context

This part belongs to the MC74VHC1G50/MC74VHC1GT50 family of single-buffer logic ICs. It is designed for applications requiring high speed and low power consumption in small footprints. The device is available in multiple package options including SC-88A, SC-74A, SOT-553, SOT-953, and UDFN6.

Replacement Considerations

MC74VHC1GT50DFT1G: Offers identical functionality but utilizes TTL-level input thresholds instead of CMOS-level thresholds.
