74LCX125SJX

Overview

The Fairchild Semiconductor 74LCX125SJX is a low voltage quad buffer with 5V tolerant inputs and outputs. It operates within a supply voltage range of 2 V to 3.6 V. The device features four non-inverting input lines and four corresponding output lines. High-level output current is specified at -24 mA, while the low-level output current is 24 mA. Static current consumption is 10 uA. The component is housed in a SOP-14 package.

Feature Summary

• Provides low voltage buffering capabilities for digital signal transmission
• Ensures compatibility with 5V tolerant I/O environments through input/output design
• Delivers non-inverting signal propagation across four independent channels

Applications

• Low voltage bus driving applications
• Interfacing between different voltage domains
• Signal buffering in portable electronic devices

Procurement Notes

Verify the manufacturer designation as Fairchild Semiconductor or its successor entities due to industry acquisitions. Confirm the specific suffix SJX corresponds to the SOP-14 package variant. Check for RoHS compliance status and lead-free certification details in the official datasheet. Ensure the component meets moisture sensitivity level requirements for your assembly process. Validate that the part number matches the exact electrical specifications required for your circuit design.

Selection Notes

Select this component when interfacing low voltage logic with 5V tolerant systems. The 74LCX125SJX offers high noise immunity and low power consumption suitable for battery-operated devices. Consider the SOP-14 package constraints for PCB layout. Verify that the 24 mA drive capability meets the load requirements of the destination circuitry. Ensure the operating temperature range aligns with the environmental conditions of the final application.

Part Context

This component belongs to the 74LCX series of low voltage CMOS logic devices. The LCX family is designed for high-speed operation with reduced power dissipation compared to older logic families. The 74LCX125 specifically functions as a quad buffer, providing signal isolation and amplification. It is widely used in consumer electronics and industrial control systems requiring reliable data transmission.

Replacement Considerations

The 74LCX125MTCX is a pin-compatible alternative in a TSSOP-14 package from the same manufacturer. Other equivalents include parts from ON Semiconductor such as the 74LCX125SJX, which shares identical electrical characteristics. Verify package dimensions and thermal performance when substituting.
