MC74LVX125MG

Overview

The MC74LVX125MG is a quad buffer and line driver manufactured by onsemi, belonging to the LVX logic series. It features four non-inverting channels with three-state outputs housed in a 14-SOIC package. The device operates within a supply voltage range of 2 V to 3.6 V. Key electrical parameters include a maximum static current of 4 uA and an operating power supply current of 40 uA. Output drive capabilities are specified at 4 mA for both high and low states. Propagation delay varies from 13.6 ns at 2.7 V to 9.7 ns at 3.3 V. The component supports surface mount installation and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Provides four independent non-inverting buffer channels with three-state output control for bus-oriented communication.
• Operates effectively within a low-voltage power supply range of 2 V to 3.6 V, suitable for portable applications.
• Features low quiescent current consumption to minimize power usage during standby or idle states.
• Delivers symmetrical output drive currents to ensure consistent signal integrity across load conditions.

Applications

• Bus-oriented systems requiring signal buffering and isolation
• Clock distribution networks for timing signals
• Memory data bus drivers in embedded controllers

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through the latest datasheet revision. Check for obsolescence notices or product change notifications prior to finalizing procurement plans to ensure long-term availability.

Selection Notes

Select this component when designing circuits that require low-voltage operation between 2 V and 3.6 V with minimal power consumption. The three-state output capability makes it suitable for multiplexed bus architectures. Ensure the application environment remains within the specified -40°C to +85°C temperature range for reliable performance.

Part Context

This part belongs to the 74LVX family of low-voltage CMOS logic devices produced by onsemi. The LVX series is designed for applications requiring operation at lower voltages than standard 5V TTL logic while maintaining compatibility with various digital interfaces. The MC74LVX125 variant specifically provides buffered outputs for driving loads on shared data lines.

Replacement Considerations

Direct substitutes may include other manufacturers' equivalents such as the SN74LVX125 or NC7SV125, provided pinouts and electrical characteristics match. Verify functional compatibility regarding propagation delay and output drive strength before substitution.
