MC74AC541M

Overview

The MC74AC541M is an octal buffer and line driver manufactured by onsemi, belonging to the AC logic series. It features eight non-inverting channels with three-state outputs housed in a TSSOP-20 package. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a high-level output current of -24 mA and a low-level output current of 24 mA. Propagation delay is specified at 8 ns at 3.3 V and 6 ns at 5 V. The component supports surface mount installation and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Features three-state outputs that allow switching between high, low, and high-impedance states to isolate the bus when not enabled.
• Utilizes a through-bus architecture where inputs and outputs are located on opposite sides of the package to facilitate microprocessor interfacing and PCB layout density.

Applications

• Memory address drivers
• Clock signal drivers
• Bus transceivers

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout compatibility and electrical characteristics. Confirm RoHS compliance status for environmental regulations. Ensure the supplier provides traceable documentation matching the manufacturer's part identification. Cross-reference the package type to avoid mechanical fit issues during integration.

Selection Notes

Select this component for applications requiring high-speed buffering with strong drive capabilities. The AC series offers faster propagation delays compared to standard HC logic. Consider the TSSOP-20 package for space-constrained designs. Verify input voltage levels match the source logic family to ensure proper signal integrity across the operating temperature range.

Part Context

This device is part of the MC74AC540/541 series of octal buffers and line drivers. The MC74AC541 serves as the non-inverting counterpart to the MC74AC540. It shares functional similarities with the MC74AC240 and MC74AC244 series but distinguishes itself through its specific through-bus pin configuration designed for improved board layout efficiency.
