MC74VHC1G125DF2G

Overview

The MC74VHC1G125DF2G is a single-channel, non-inverting buffer and line driver manufactured by onsemi. It belongs to the VHC (Very High Speed CMOS) logic family and features three-state outputs for bus-oriented applications. The device operates within a supply voltage range of 2.0 V to 5.5 V. It utilizes an SC-70-5 surface-mount package. Key electrical parameters include a propagation delay of 3.6 ns at 5.0 V and output drive currents of ±8 mA. The component supports a wide operating temperature range from -55°C to +125°C.

Feature Summary

• Provides high-speed signal buffering with low propagation delay characteristics typical of VHC technology.
• Features three-state outputs allowing direct connection to bus lines without external pull-up or pull-down resistors.
• Operates across a broad voltage range compatible with both 2.5 V and 5 V systems.

Applications

• Bus-oriented memory and signal driving in portable equipment
• Clock buffering and distribution circuits
• High-density data acquisition systems

Procurement Notes

Verify the specific suffix 'DF2G' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint for the SC-70-5 package. Check for any recent lifecycle status updates such as obsolescence or recommended new replacements directly from onsemi official channels before finalizing procurement plans.

Selection Notes

Select this component when a single-channel buffer with three-state control is required in space-constrained designs. The VHC series offers superior speed compared to standard HC logic while maintaining CMOS power efficiency. Consider the 2.0 V to 5.5 V operating range if the system requires flexibility between different voltage domains. Verify that the SC-70-5 package dimensions fit the available board real estate constraints.

Part Context

This part is part of onsemi's 74VHC1Gxx series of single-gate logic devices designed for low-voltage applications. The VHC series represents a performance upgrade over previous generations, offering faster switching speeds and lower power consumption. These devices are commonly used in consumer electronics, telecommunications, and computing applications where small form factors and high performance are critical requirements.

Replacement Considerations

Check for equivalent parts from other manufacturers such as NXP or STMicroelectronics that offer similar VHC single-buffer specifications in SC-70-5 packages. Ensure pinout compatibility and electrical parameter matching before substitution. Verify if alternative suffixes indicate different packaging options rather than functional changes.
