• Provides four non-inverting buffers with controlled three-state output control
• Utilizes advanced CMOS technology for low power consumption and high noise immunity

Applications

• Portable consumer electronics requiring low voltage operation
• Mixed-voltage bus driving applications
• Memory module data buffering

Procurement Notes

Verify the specific suffix MX against the official datasheet to confirm the TSSOP-14 package configuration. Confirm RoHS compliance status through the manufacturer's material declaration. Check current lifecycle status as distribution availability may vary by region. Ensure the ordering part number matches the required tape and reel or cut tape packaging format specified in the procurement documentation.

Selection Notes

Select this component when designing systems that require interface between 2V logic domains and 5V tolerant peripherals. The LCX series offers superior performance compared to standard LVC devices in terms of leakage current and speed at lower voltages. Verify that the operating temperature range of -40°C to +85°C meets the environmental requirements of the target application.

Part Context

This component belongs to the 74LCX family of low-voltage CMOS logic devices. The LCX series is designed specifically for applications demanding low power dissipation and high speed operation. It serves as a bridge between different voltage domains, enabling seamless integration of legacy 5V components with modern low-voltage processors and memory systems.

Replacement Considerations

Compatible substitutes include the 74LCX125MTCX and 74LCX125SJX from onsemi. Other manufacturers offer equivalent parts such as the TC74LCX125F(EL) from Toshiba. Verify pin compatibility and electrical specifications before substitution.
