74LCX541SJX

Overview

The MC74LCX541SJX is an octal buffer and line driver manufactured by onsemi, belonging to the LCX logic family. It features non-inverting outputs with a flow-through pinout architecture, where inputs and outputs are located on opposite sides of the package to facilitate PCB layout. The device operates within a supply voltage range of 2 V to 3.6 V. It provides three-state outputs with high drive capability, sourcing up to -24 mA and sinking up to 24 mA per pin. The static current consumption is typically 10 µA. The component is housed in a 20-SOP surface-mount package.

Feature Summary

• Flow-through pinout design allows inputs and outputs to be positioned on opposite sides of the package for simplified circuit board layout.

Applications

• Memory address and data bus driving
• Clock signal distribution
• Microprocessor output port interfacing

Procurement Notes

Verify the specific suffix SJX against the official datasheet to confirm the exact package type and tape-and-reel specifications. Confirm RoHS compliance status as required by your manufacturing standards. Check for obsolescence notices or lifecycle changes directly from onsemi documentation before finalizing procurement plans.

Selection Notes

Select this component when low voltage operation between 2 V and 3.6 V is required alongside high-speed performance. The LCX series offers CMOS compatibility with TTL input levels. Ensure the application benefits from the flow-through pinout for dense PCB routing compared to standard parallel I/O configurations.

Part Context

This part is part of the 74LCX541 series of octal buffers. It serves as the non-inverting counterpart to the 74LCX540. The LCX family is designed for low-voltage applications, offering performance comparable to faster logic families while maintaining low power consumption typical of CMOS technology.

FAQ

What is the polarity of the 74LCX541SJX outputs?

The outputs are non-inverting, meaning the output signal follows the input signal state directly.

Does the 74LCX541SJX support three-state operation?

Yes, the device features three-state outputs controlled by enable signals, allowing isolation from the bus when not active.
