MC74VHC1GT126DT1G-Q

Overview

The MC74VHC1GT126DT1G-Q is a single-channel, non-inverting buffer and line driver from the 74VHC logic family. It features three-state outputs controlled by an active-high enable input. The device operates within a supply voltage range of 2.0 V to 5.5 V and provides high output drive capability with 8 mA sink and source currents. It is housed in a compact SC-74A (TSOT-23-5) surface-mount package.

Feature Summary

• Single-channel non-inverting buffer design
• Three-state output control via active-high enable
• High noise immunity typical of CMOS technology
• Automotive-grade qualification for reliability

Applications

• Automotive electronic systems requiring AEC-Q100 compliance
• Memory address drivers in bus-oriented architectures
• Clock signal buffering and distribution
• General-purpose signal isolation and driving

Procurement Notes

Verify the specific suffix 'Q' indicates automotive grade qualification and PPAP capability. Confirm the package designation matches the required footprint. Ensure the datasheet revision aligns with current manufacturing specifications. Check for any recent PCN notifications regarding assembly or material changes.

Selection Notes

Select this component when a single-channel, non-inverting buffer with three-state control is required in space-constrained designs. The VHC series offers speed comparable to LVC while maintaining CMOS compatibility. The automotive qualification makes it suitable for harsh environments where standard commercial parts may not suffice.

Part Context

This part belongs to onsemi's MC74VHC1G series of single-gate logic devices. These components are designed to provide high-density solutions for modern electronic applications.
