74AC540SJX

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74AC540SJX is an octal buffer and line driver belonging to the AC logic series. It features eight inverted outputs with three-state capability, allowing connection to bus lines. The device utilizes a flow-through architecture where inputs and outputs are positioned on opposite sides of the package, facilitating easier interface to microprocessors and improved printed circuit board density. It operates within a voltage range of 2V to 6V.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'SJX' against official Fairchild documentation to confirm the exact package type (SOP) and tape-and-reel packaging configuration. Ensure the component matches the required operating temperature range and electrical specifications for your design. Cross-reference the manufacturer part number with current datasheets to confirm availability status and any potential obsolescence notices.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal inverting buffer with three-state outputs is required for high-density PCB layouts. The flow-through architecture distinguishes it from standard parallel I/O devices, making it suitable for applications requiring direct microprocessor interfacing. Consider the 74AC541 if non-inverting logic is preferred instead.

Buffers, Drivers, Receivers, Transceivers Part Context

This component is part of the 74AC family of high-speed CMOS logic devices. It serves as the inverting counterpart to the 74AC541. Functionally, it shares similarities with the 74AC240 and 74ACT240 but offers distinct input/output placement advantages for system layout optimization.
