74LCX541MSA

Overview

The onsemi 74LCX541MSA is a low voltage octal buffer and line driver featuring five-volt tolerant inputs and outputs. It operates within a supply voltage range of 2.0V to 3.6V, with specific performance specifications provided for the 2.3V to 3.6V range. The device delivers a maximum propagation delay of 6.5ns at 3.3V and maintains a maximum quiescent supply current of 10µA. It provides an output drive capability of ±24mA at VCC = 3.0V. The component utilizes a 20-lead Shrink Small Outline Package (SSOP) conforming to JEDEC MO-150 standards.

Feature Summary

• Provides non-inverting buffering for eight channels with flow-through architecture suitable for microprocessor output ports.
• Features five-volt tolerant inputs and outputs, enabling safe interfacing between low voltage logic and 5V signal environments.
• Supports live insertion and withdrawal through power-down high impedance states when OE is tied to VCC via a pull-up resistor.

Applications

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

Procurement Notes

Verify the ordering suffix 'MSA' corresponds to the 20-lead SSOP package configuration. Confirm that the part number reflects the transition from Fairchild Semiconductor nomenclature to ON Semiconductor systems, as underscores may have been replaced by dashes in updated databases. Ensure compliance with the specified operating temperature range and absolute maximum ratings during integration.

Selection Notes

Select this component for applications requiring low voltage operation with 5V tolerance capabilities. The flow-through pinout facilitates easier PCB layout compared to similar devices like the LCX244. Consider the ±24mA drive strength for bus loading requirements and verify that the 6.5ns propagation delay meets system timing constraints at the target supply voltage.

Part Context

This device belongs to the LCX family of low voltage CMOS logic components. It serves as the non-inverting counterpart to the LCX540 and offers functional similarities to the LCX244 while providing distinct pinout advantages for board density. The technology combines advanced CMOS processes to achieve high-speed operation with low power dissipation.

Replacement Considerations

Check for equivalent parts such as 74LCX541WM or 74LCX541MTC if different package styles are required. Verify compatibility with other manufacturers' LCX541 variants ensuring pinout and electrical characteristics match the design requirements.
