74LCX541MTCX

Overview

The onsemi 74LCX541MTCX is an octal buffer and line driver featuring non-inverting logic with three-state outputs. It operates within a supply voltage range of 2.0V to 3.6V, supporting inputs up to 5.5V for system compatibility. The device utilizes advanced CMOS technology to achieve high-speed performance, with a maximum propagation delay of 6.5ns at 3.3V and 7.5ns at 2.7V. It provides robust output drive capabilities of ±24mA at 3.0V and maintains low quiescent current of 10µA. Packaged in a 20-lead TSSOP (MTC20), it includes ESD protection exceeding 2000V human body model.

Feature Summary

• Features 5V tolerant inputs and outputs, enabling direct interfacing between low-voltage logic and 5V signal environments.
• Provides high-speed operation with low propagation delay while maintaining CMOS low power dissipation characteristics.
• Supports live insertion and withdrawal through power-down high impedance states for both inputs and outputs.

Applications

• Memory and address drivers
• Clock drivers
• Bus-oriented transmitter/receivers

Procurement Notes

Verify the specific package designation matches the required footprint, as the MTC suffix indicates a 20-lead Thin Shrink Small Outline Package. Confirm that the ordering number aligns with ON Semiconductor's current nomenclature standards following the Fairchild integration, particularly regarding underscore versus dash usage in part numbers. Ensure compliance with JEDEC moisture sensitivity levels if applicable to the manufacturing process.

Selection Notes

Select this component when designing systems requiring interface between 2.3V–3.6V logic and 5V environments. The flow-through architecture facilitates PCB layout by placing inputs and outputs on opposite sides. Consider the ±24mA drive strength for bus loading requirements and verify that the 5.5V input tolerance meets the source signal specifications without additional level shifting.

Part Context

This device belongs to the LCX family of low-voltage CMOS logic devices. It serves as the non-inverting counterpart to the LCX540. The product line is designed for applications demanding high speed and low power consumption, fabricated using advanced CMOS technology. It shares functional similarities with the LCX244 but offers a distinct pinout arrangement optimized for microprocessor output ports and board density.

Replacement Considerations
