MC74LCX125D

Overview

The MC74LCX125D is a low-voltage quad buffer and line driver from the onsemi 74LCX logic family. It features four non-inverting buffers with three-state outputs, designed for high-speed data transmission. The device operates within a supply voltage range of 2.0 V to 3.6 V. It provides robust 5V tolerant I/O capabilities, allowing safe interfacing between low-voltage components and legacy 5V systems. The package type is TSSOP-14.

Feature Summary

• Provides four independent non-inverting buffer channels with three-state output control.
• Features 5V tolerant inputs and outputs, enabling direct interface with 5V CMOS and TTL devices while operating at lower voltages.
• Designed for high-speed operation with low dynamic power consumption suitable for battery-powered applications.

Applications

• Memory module address and data bus buffering
• Clock distribution networks in low-voltage systems
• Signal translation between 3.3V/2.5V domains and 5V peripherals

Procurement Notes

Verify the exact suffix against the manufacturer's current datasheet to confirm package style and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the ordering code with official distributor catalogs to avoid obsolete variants or incorrect pinout configurations.

Selection Notes

Select this component when driving multiple loads from a single source in mixed-voltage environments. The 5V tolerance eliminates the need for external level shifters. Consider the TSSOP-14 package for space-constrained PCB layouts requiring surface-mount technology.

Part Context

This part belongs to the 74LCX series, which utilizes advanced CMOS technology to achieve speeds comparable to LVC logic but with lower power dissipation. It is part of a broader family of logic gates including inverters, NAND gates, and flip-flops, all sharing similar electrical characteristics and pinouts where applicable.
