MC74LVX125DR2G

Overview

The MC74LVX125DR2G is a low-voltage CMOS quad buffer and line driver manufactured by onsemi. It operates within a supply voltage range of 2 V to 3.6 V and features four non-inverting channels with three-state outputs. The device utilizes silicon gate CMOS technology for high-speed operation while maintaining low power consumption. Key electrical parameters include a propagation delay of 13.6 ns at 2.7 V and 9.7 ns at 3.3 V, with output drive capabilities of ±4 mA. It is housed in a 14-pin SOIC package and supports surface-mount installation.

Feature Summary

• Provides four independent non-inverting buffer channels with three-state output control for bus-oriented applications.
• Operates across a wide low-voltage supply range from 2 V to 3.6 V, compatible with modern low-power digital systems.
• Features high-speed performance with propagation delays as low as 9.7 ns at 3.3 V using advanced silicon gate CMOS technology.

Applications

• Memory and address buffering in portable electronic devices
• Clock distribution and timing signal conditioning
• Driving capacitive loads in low-voltage digital circuits

Procurement Notes

Verify the specific ordering suffix DR2G corresponds to the SOIC-14 tape and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the component meets the required operating temperature range of -40°C to +85°C for the intended application environment.

Selection Notes

Select this component when a quad buffer with three-state capability is required for low-voltage logic families. It serves as a direct functional replacement for standard 74LVX125 devices in designs requiring 2V to 3.6V operation. Consider the ±4 mA drive strength and 13.6 ns delay characteristics against system timing requirements.

Part Context

This part belongs to the MC74LVX series of low-voltage CMOS logic devices produced by onsemi. The LVX series is designed for applications requiring operation between 2.0 V and 3.6 V, bridging the gap between traditional 5 V and lower voltage standards. The MC74LVX125 specifically addresses the need for buffered signals in battery-powered and portable equipment.

Replacement Considerations

The 74LVX125MX is a documented alternative from the same manufacturer family offering similar quad buffer functionality. Verify pinout compatibility and electrical specifications before substitution. Other generic 74LVX125 equivalents may be considered if they meet the 2V–3.6V supply and SOIC-14 package constraints.
