74ACT541MTC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACT541MTC is an octal buffer and line driver featuring non-inverting logic with three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature from -40°C to +85°C. The device provides high drive capability, sourcing and sinking up to 24 mA per output. Propagation delay is typically 4.5 ns at 5.0 V with a 50 pF load. Inputs are TTL-compatible, ensuring direct interface with standard logic families.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'MTC' corresponds to the TSSOP-20 package and tube shipping configuration. Confirm RoHS compliance status and lead-free marking requirements against the latest manufacturer documentation before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a non-inverting octal buffer with TTL-compatible inputs is required. Ensure the application voltage remains within the 4.5 V to 5.5 V range. Consider the TSSOP-20 package dimensions for thermal management and board space constraints relative to SOIC alternatives.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74AC/ACT logic family, designed for high-speed CMOS applications. It serves as a functional equivalent to similar octal buffers but distinguishes itself through its specific pinout arrangement and TTL input compatibility, optimizing it for modern digital system architectures requiring efficient data routing.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The MC74ACT541DWR2G offers identical electrical performance in a SOIC-20 tape-and-reel package. Verify package footprint compatibility and shipping format differences before substituting.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the 74ACT541MTC differ from the 74AC541?

The 74ACT541 features TTL-compatible inputs, whereas the 74AC541 uses standard CMOS input thresholds. Both share the same octal buffer functionality and package options.

What controls the three-state output condition?

The outputs enter a high-impedance state when both OE1 and OE2 inputs are driven HIGH. They remain enabled when either input is LOW.
