Overview
The MC74VHC1GT125D1G is a single-channel, non-inverting buffer manufactured by onsemi. It operates within a supply voltage range of 3 V to 5.5 V and features three-state outputs. The device utilizes high-speed CMOS technology and provides an output current capability of 8 mA for both high and low states. It is housed in a compact SOT-23-5 (TSOP-5) surface-mount package. The component supports an operating temperature range from -55°C to +125°C and includes input protection structures compatible with 5 V logic levels despite lower supply voltages.
Feature Summary
- Single-channel non-inverting buffer design
- Three-state output configuration
- High noise immunity via buffered output structure
- Input protection allowing 5 V tolerance
Applications
- Interface between 5 V circuits and 3 V circuits
- Clock buffering and distribution
- Data bus driving applications
Procurement Notes
Verify the exact part number suffix carefully, as the provided model contains a potential typographical error compared to standard manufacturer listings. Confirm availability status, as this specific variant may be obsolete or discontinued. Ensure compatibility with existing PCB footprints and verify RoHS compliance documentation before procurement.
Selection Notes
Select this component when a single-channel, non-inverting buffer with three-state control is required in a minimal footprint. It is suitable for applications needing interface between different voltage domains, specifically 5 V to 3 V systems. Consider the SOT-23-5 package constraints and the 8 mA drive strength requirements for the target load.
Part Context
This component belongs to the 74VHC series of high-speed CMOS logic devices. The series is characterized by low power consumption and wide operating voltage ranges. The MC74VHC1GT125 variant specifically offers a single buffer channel with three-state outputs, distinguishing it from non-three-state buffers like the MC74VHC1G125.
Replacement Considerations
Public confirmed substitute part numbers include 74AHCT1G125GV,125 from Nexperia USA Inc. and SN74AHCT1G125DBVR from Texas Instruments. Verify pinout compatibility and electrical specifications against these alternatives.
