MC74VHC125DT

Overview

The MC74VHC125DT is a non-inverting buffer from the VHC logic family, manufactured by onsemi. It features four independent channels with three-state outputs in a 14-pin TSSOP package. The device operates within a supply voltage range of 2V to 5.5V and supports output drive currents of ±8mA. It exhibits a maximum propagation delay of 9ns at 5V and functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides four independent non-inverting buffer channels for signal amplification
• Features three-state outputs to facilitate bus-oriented architectures
• Supports wide supply voltage operation from 2V to 5.5V

Applications

• Bus-oriented systems requiring signal buffering
• Clock distribution networks
• Memory data bus drivers

Procurement Notes

Verify the specific suffix 'DT' corresponds to the TSSOP-14 package configuration required for your PCB layout. Confirm that the operating temperature range of -40°C to +85°C meets your environmental specifications. Ensure compatibility with the 2V to 5.5V supply voltage requirements of your target circuit design before finalizing procurement.

Selection Notes

Select this component when a quad-channel buffer with three-state control is needed for 3.3V or 5V digital systems. The VHC series offers high-speed performance comparable to older technologies while maintaining low power consumption. Consider the TSSOP package dimensions if space constraints are a primary factor in the board design process.

Part Context

This part belongs to the 74VHC125 series of high-speed CMOS logic devices. It serves as a standard solution for driving high-capacitance loads in digital communication interfaces. The device is widely used in consumer electronics and industrial equipment where reliable signal integrity and moderate speed are required.

Replacement Considerations

Check for MC74VHC125DTR2G (tape and reel version) or MC74VHC125DG (SOIC-14 package). Verify pinout compatibility with existing footprints before substitution.
