74LCX125MTC

Overview

The Fairchild Semiconductor 74LCX125MTC is a low-voltage quad buffer with 5V tolerant inputs, housed in a 14-TSSOP package. It operates within a supply voltage range of 2 V to 3.6 V and features non-inverting logic. The device provides high-level output current of -24 mA and low-level output current of 24 mA, with a static current of 10 uA. It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides four independent non-inverting buffers with 5V tolerant inputs for safe interface between 5V systems and 3V systems.
• Features three-state outputs controlled by enable signals to manage bus line traffic effectively.
• Designed for low power consumption and low noise applications suitable for portable electronics.

Applications

• Interface buffering between 5V CMOS devices and 3V LVC/LCX/LVT families
• Memory address and data bus driving in portable equipment
• Clock distribution and signal buffering in consumer electronics

Procurement Notes

Verify the exact suffix against the manufacturer's current datasheet to confirm pinout and electrical specifications match your design requirements. Ensure the component source is authorized to guarantee authenticity and compliance with RoHS standards. Cross-reference the ordering number with official onsemi or Fairchild documentation to avoid substitution errors during production.

Selection Notes

Select this component when interfacing 5V logic with lower voltage 3.3V systems requiring high drive capability. The 14-TSSOP package offers space efficiency for surface-mount designs. Consider the 24 mA output current for driving moderate capacitive loads without external buffering solutions.

Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices. It shares functional similarities with other LCX buffers but is distinct from LVX or HC series due to its specific voltage tolerance and drive characteristics. The MTC suffix denotes the 14-lead thin-shrink small-outline package type used in compact electronic assemblies.

Replacement Considerations

Check for 74LCX125MX or 74LCX125MTX as potential pin-compatible alternatives from the same family. Verify that any substitute maintains the 5V input tolerance and 3-state output functionality required for your specific circuit application.
