MC74VHC125MG

Overview

The MC74VHC125MG is a quad buffer and line driver from onsemi's VHC logic family, housed in a 16-pin SOIC package. It features non-inverting buffers with three-state outputs, operating within a supply voltage range of 2.0 V to 5.5 V. The device provides high-speed performance with propagation delays as low as 9 ns at 5.0 V. It supports output drive currents of ±8 mA and operates across an extended temperature range of -55°C to +125°C.

Feature Summary

• Quad configuration providing four independent non-inverting buffer channels
• Three-state output capability for bus-oriented applications
• Extended industrial temperature operation up to +125°C

Applications

• Bus-oriented memory and address drivers
• Clock buffering and distribution
• High-speed data transmission lines

Procurement Notes

Verify the specific suffix 'M' corresponds to the SOIC-16 package variant when sourcing. Confirm RoHS compliance status through official datasheets or manufacturer documentation prior to procurement. Ensure the ordering part number matches the required package style and temperature grade.

Selection Notes

Select this component for designs requiring multiple buffered signals with tri-state control. The VHC series offers CMOS power consumption with speed comparable to older bipolar technologies. Verify that the 2.0 V minimum supply voltage meets system requirements for lower voltage logic interfaces.

Part Context

This part belongs to the 74VHC125 family of quad buffers. It serves as a standard interface solution for digital systems requiring signal isolation and drive enhancement. The VHC technology ensures compatibility with various logic families while maintaining low static power dissipation.

Replacement Considerations

Compatible substitutes include MC74VHC125DTR2G (SOIC-16) and MC74VHC125DTG (SOIC-16). Verify pinout and electrical specifications match before substitution.
