MC74VHC125DG

Overview

The MC74VHC125DG is a quad non-inverting buffer and line driver manufactured by onsemi. It operates within a supply voltage range of 2 V to 6 V and utilizes CMOS logic technology. The device features four independent channels with three-state outputs, housed in a 14-pin SOIC package. Key electrical characteristics include a maximum propagation delay of 9 ns at 3.3 V and 7 ns at 5 V. Output drive capabilities are specified at -24 mA for high-level and 24 mA for low-level currents. The component supports an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Provides four independent non-inverting buffer channels with three-state output control.
• Supports wide supply voltage operation ranging from 2 V to 6 V.
• Delivers high current drive capability suitable for driving transmission lines.

Applications

• Clock buffering and distribution systems
• Memory data bus drivers
• High-speed signal transmission interfaces

Procurement Notes

Verify the specific suffix 'DG' against the manufacturer's official datasheet to confirm the exact package type and tape/reel specifications. Ensure the ordered part matches the required RoHS compliance status and lead time requirements. Cross-reference the ordering information with authorized distributors to confirm availability and authenticity before finalizing procurement.

Selection Notes

Select this component when a quad buffer with three-state functionality is required for 2 V to 6 V logic systems. Consider the 14-SOIC package constraints and thermal dissipation limits. Evaluate the propagation delay specifications against system timing requirements to ensure compatibility with target clock speeds and signal integrity standards.

Part Context

This component belongs to the 74VHC series of high-speed CMOS logic devices produced by onsemi. The 74VHC family is designed to be pin-compatible with 74HC logic while offering improved performance characteristics. The MC74VHC125 variant specifically provides buffered outputs with enable controls, distinguishing it from standard buffers without tri-state capabilities.
