74LCX125SJ

Overview

The onsemi 74LCX125SJ is a low-voltage quad buffer with 5V tolerant I/O, belonging to the LCX logic series. It features four non-inverting inputs and outputs housed in a 14-pin SOP package. The device operates within a supply voltage range of 2 V to 3.6 V, drawing a typical static current of 10 µA. It provides high-level output currents up to -24 mA and low-level output currents up to 24 mA.

Feature Summary

• Provides 5V tolerant input/output capabilities for mixed-voltage system interfacing
• Features three-state outputs for bus-oriented applications
• Operates at low supply voltages down to 2 V

Applications

• Memory data bus buffering
• Clock distribution networks
• Signal level translation between different voltage domains

Procurement Notes

Verify the specific suffix 'SJ' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status and check for end-of-life notifications, as availability may be limited for older packaging variants.

Selection Notes

Select this component when designing systems requiring low-power operation with 5V tolerance. Ensure the required operating temperature range matches the specified limits. Verify that the load capacitance requirements are within the device's driving capability specifications.

Part Context

This part belongs to the 74LCX family of low-voltage CMOS logic devices. It serves as a buffer or line driver, offering high-speed performance with low power consumption. The LCX series is designed to replace higher voltage logic families in modern low-voltage digital circuits.

Replacement Considerations

Check for direct replacements such as the 74LCX125MTCX (TSSOP-14) or 74LCX125BQX (DQFN-14). Verify functional equivalence and pin compatibility before substitution.
