74LCX125MTCX

Overview

The onsemi 74LCX125MTCX is a low-voltage quad buffer with 5V tolerant I/O, belonging to the 74LCX logic series. It features four non-inverting input lines and four output lines housed in a TSSOP-14 package. The device operates within a supply voltage range of 2 V to 3.6 V. It provides high-level output current of -24 mA and low-level output current of 24 mA. Static current is specified at 10 µA. The component supports operation from -40 °C to +85 °C.

Feature Summary

• Provides five-volt tolerant input/output capability for interfacing between different voltage domains
• Features low static power consumption suitable for battery-operated applications
• Includes internal clamp circuits to handle fast-rising transient voltages

Applications

• Memory bus buffering in portable electronic devices
• Clock signal distribution in consumer electronics
• Interface bridging between 3.3V and 5V logic systems

Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm package type and tape/reel specifications. Ensure the ordering part number matches the required temperature grade and RoHS compliance status. Cross-reference the manufacturer's latest documentation for any pinout or electrical characteristic updates before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring low-voltage operation with robust 5V tolerance. The quad buffer configuration allows for multiple signal paths in a single package. Consider the TSSOP-14 footprint for surface-mount assembly constraints. Verify that the 24 mA drive current meets the load requirements of the destination logic gates.

Part Context

This device is part of the 74LCX family, which utilizes advanced CMOS technology to achieve high-speed performance with low power dissipation. The LCX series is designed to replace older HC/HCT logic families in modern low-voltage designs. It offers improved noise immunity and reduced propagation delay compared to standard CMOS counterparts.

Replacement Considerations

Check for direct equivalents such as the NCV74LCX125MTCX for automotive-grade requirements. Verify functional compatibility with other 74LCX125 variants from different manufacturers regarding pinout and electrical parameters.
