74ACTQ541MTC

Buffers, Drivers, Receivers, Transceivers Overview

The 74ACTQ541MTC is an octal buffer and line driver manufactured by onsemi, utilizing FACT Quiet Series technology. It features non-inverting 3-STATE outputs with inputs and outputs positioned on opposite sides of the package for flow-through architecture. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature from -40°C to +85°C. Key electrical characteristics include TTL-compatible inputs, output source/sink currents of 24 mA, and propagation delays ranging from 2.0 ns to 7.5 ns at 5.0V.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the component matches the specific MTC20 package designation (20-Lead Thin Shrink Small Outline Package). Confirm the manufacturer origin, as this part was originally produced by Fairchild Semiconductor before its acquisition by onsemi. Ensure compliance with RoHS standards if required for the specific application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a high-density layout is required due to its flow-through pinout arrangement. It is suitable for applications demanding low simultaneous switching noise and robust ESD protection. Consider the 74ACTQ541MTCX variant if tape and reel packaging is preferred over tube packaging for automated assembly processes.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ACT logic family, specifically designed for high-speed digital applications. It serves as an octal buffer or line driver, functionally similar to the 74ACTQ244 but distinguished by its input/output orientation. The integration of GTO output control and undershoot correction enhances its performance in complex bus systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ACTQ541MTCX is available as an alternative packaging option using tape and reel instead of tubes. Other variants such as the SOIC (74ACTQ541SC) and PDIP (74ACTQ541PC) packages offer different form factors while maintaining identical electrical functionality.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the maximum quiescent supply current for the 74ACTQ541?

The maximum quiescent supply current (ICC) is 40.0 µA at VCC = 5.5V and TA = -40°C to +85°C.

How does the 74ACTQ541 differ from the 74ACTQ244?

While functionally similar, the 74ACTQ541 provides a flow-through architecture where inputs are on the opposite side from outputs, unlike the 74ACTQ244.
