74LCX541SJ

Overview

The MC74LCX541SJ is an octal buffer and line driver manufactured by onsemi. It operates within a supply voltage range of 2.3 V to 3.6 V. The device features three-state outputs controlled by two active-low output enable inputs (OE1 and OE2). When enabled, data transfers from the A inputs to the Y outputs without inversion. The component utilizes CMOS technology for low power consumption and includes overvoltage tolerant inputs capable of withstanding signals up to 5.5 V.

Feature Summary

• Octal configuration providing eight independent non-inverting buffers or line drivers in a single package
• Three-state output architecture allowing bus-oriented connections through high-impedance states
• Dual active-low output enable inputs facilitating flexible control logic integration
• Overvoltage tolerant input structure supporting operation in mixed-voltage environments

Applications

• Memory module buffering and driving
• Clock distribution circuits
• Data bus transceivers
• Portable equipment logic interfaces

Procurement Notes

Verify the specific suffix SJ against official datasheets to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and operating temperature ratings match project requirements. Ensure pinout compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component when designing systems requiring low-voltage operation between 2.3 V and 3.6 V. It is suitable for applications needing high noise immunity and low power dissipation. Verify that input signal levels remain within the specified overvoltage tolerance limits to prevent damage.

Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices. It serves as an octal buffer variant within the broader family of high-performance digital logic components designed for portable and battery-operated applications requiring efficient power management.

Replacement Considerations

Check for direct equivalents such as the MC74LCX541MTC or other LCX541 variants from onsemi. Cross-reference pinouts and electrical characteristics with competitors like NXP or Texas Instruments if sourcing alternatives.
