Overview
The MC74VHC1G125DFT2G-Q is a single non-inverting 3-state buffer from the VHC logic family, manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 5.5 V and features CMOS-level input thresholds. The device provides high noise immunity through a buffered three-stage internal circuit and includes over-voltage tolerant inputs and outputs up to 5.5 V. It supports partial power down protection via IOFF and delivers source/sink currents of 8 mA at 3.0 V. The component is housed in an SC-88A package and is qualified under AEC-Q100 standards.
Feature Summary
- CMOS-level input thresholds for standard logic interfacing
- Over-voltage tolerant inputs and outputs up to 5.5 V
- Partial power down protection with IOFF support
- High noise immunity via buffered three-stage output
Applications
- Automotive electronic systems requiring AEC-Q100 qualification
- Interfacing 5 V circuits to 3 V circuits
- Battery backup applications
- Hot insertion scenarios
Procurement Notes
Verify that the ordering suffix matches the specific device code and pin orientation required for your design. Confirm the presence of the -Q suffix indicates AEC-Q100 qualification and PPAP capability. Ensure the package type corresponds to the SC-88A outline specified in the datasheet. Check RoHS compliance status as indicated by the G suffix or microdot marking.
Selection Notes
Select this component when a single-channel non-inverting buffer with 3-state control is needed for automotive or industrial environments. The CMOS input threshold distinguishes it from TTL-threshold variants. Consider the SC-88A footprint constraints and verify thermal dissipation requirements against the maximum ratings table for your specific operating conditions.
Part Context
This part belongs to the MC74VHC1G125 series, which includes variants with different input thresholds and packages. The -Q suffix denotes automotive-grade production with unique site and control change requirements. Other related parts include the MC74VHC1GT125 series featuring TTL-level inputs.
