MC74VHC1G126DF1G

Overview

The MC74VHC1G126DF1G is a single-channel, non-inverting buffer and line driver from onsemi's VHC logic family. It features a CMOS construction with a wide operating supply voltage range of 2.0 V to 5.5 V. The device provides three-state outputs capable of sourcing and sinking up to 8 mA. It operates within an extended temperature range of -55°C to +125°C and is housed in a compact SC-70-5 surface-mount package.

Feature Summary

• Single-channel non-inverting buffer design for signal isolation
• Three-state output capability for bus-oriented applications
• Extended industrial temperature rating for harsh environments

Applications

• Bus-oriented memory and signal switching
• Clock buffering and distribution
• High-speed data transmission lines

Procurement Notes

Verify the specific suffix DF1G against the official datasheet to confirm the SC-70-5 package configuration. Confirm that the component meets AEC-Q100 requirements if automotive qualification is necessary for the target application. Ensure compatibility with the intended supply voltage levels before integration.

Selection Notes

Select this component when a single-channel, non-inverting buffer with three-state control is required in a small SC-70-5 footprint. It is suitable for designs needing operation across a broad voltage range from 2 V to 5.5 V. Consider the extended temperature range if the environment exceeds standard commercial limits.

Part Context

This part belongs to the MC74VHC1G126 series of single-buffer devices. It shares functional similarities with other members of the VHC family but is distinguished by its specific packaging and suffix designation. The series is designed for low-power, high-speed digital applications requiring signal integrity.

Replacement Considerations

Check for direct pin-compatible alternatives within the same VHC family. Verify that any substitute maintains the same three-state functionality and voltage specifications.
