MC74VHC1GT125MU1TCG-Q

Overview

The MC74VHC1GT125MU1TCG-Q is a single non-inverting 3-state buffer from the VHC logic family, designed for operation between 2.0 V and 5.5 V. It features TTL-level input thresholds and provides high noise immunity with stable output. The device supports partial power down protection via IOFF and includes over-voltage tolerant inputs/outputs up to 5.5 V. It is housed in a UDFN6 package (1.45 x 1.0 mm) and meets AEC-Q100 qualification standards.

Feature Summary

• Single-channel non-inverting buffer with 3-state output control
• TTL-compatible input thresholds for direct interfacing
• Partial power-down protection capability
• AEC-Q100 qualified for automotive reliability

Applications

• Automotive electronic systems requiring unique site control
• Portable devices operating at low voltages
• Battery-powered consumer electronics
• High-density board designs using small footprints

Procurement Notes

Verify the specific suffix 'Q' indicates AEC-Q100 qualification and PPAP capability as required by your application's quality standards. Confirm the MU1TCG suffix corresponds to the UDFN6 1.45x1.0mm package with 0.5P pitch. Ensure compliance with RoHS and Halogen-free material requirements before finalizing procurement specifications.

Selection Notes

Select this component when a single-channel buffer with TTL input compatibility is needed in a compact UDFN6 footprint. It is suitable for applications requiring 3-state bus holding or line driving where partial power-down protection is necessary. Consider the AEC-Q100 qualification if the design targets automotive environments or requires strict supply chain control changes.

Part Context

This part belongs to the MC74VHC1G125/MC74VHC1GT125 series of single non-inverting 3-state buffers. The 'T' designation specifies TTL-level input thresholds, distinguishing it from the CMOS-threshold variant. The '-Q' suffix denotes automotive qualification, while 'MU1TCG' identifies the specific UDFN6 package type and shipping configuration.
