74LCX125SJX

Overview

The onsemi 74LCX125SJX is a low-voltage quad buffer with 5V tolerant I/O, belonging to the LCX logic series. It operates within a supply voltage range of 2 V to 3.6 V and features non-inverting polarity. The device provides four input and four output lines in an SOP-14 package. Key electrical parameters include a high-level output current of -24 mA and a low-level output current of 24 mA. Static current is specified at 10 µA.

Feature Summary

• Provides low-voltage buffering for digital signals
• Features 5V tolerant inputs for mixed-voltage interfacing
• Offers non-inverting signal transmission
• Supports high drive capability with defined output currents

Applications

• Buffering data buses in low-voltage systems
• Interfacing between different voltage domains
• Signal conditioning for digital communication lines

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notices, as some listings indicate obsolescence. Ensure the specific suffix matches required packaging and temperature specifications before procurement.

Selection Notes

Select this component when low-voltage operation between 2 V and 3.6 V is required alongside 5V tolerance. Consider the SOP-14 package constraints and ensure the 24 mA drive current meets load requirements. Verify compatibility with system noise margins and switching speed needs typical of the LCX series.

Part Context

This part belongs to the 74LCX family of CMOS logic devices designed for low-voltage applications. It serves as a buffer driver, distinct from transceivers like the MC74LCX245DT which offer bidirectional control. The SJX suffix typically denotes a specific tape-and-reel packaging option within the standard SOP-14 form factor.
