74ACT541SC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACT541SC is an octal buffer and line driver featuring three-state outputs, housed in a SOIC-20 package. 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 non-inverting logic with TTL-compatible inputs. Electrical characteristics include a maximum propagation delay of 7.5 ns at 5 V, output source/sink currents of 24 mA, and a maximum quiescent supply current of 40 µA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features a flow-through architecture with inputs and outputs located on opposite sides of the package to facilitate microprocessor interface and PCB layout density.
• Provides three-state outputs that allow high impedance isolation when disabled, preventing bus interference.
• Includes TTL-compatible inputs for direct interfacing with standard TTL logic circuits.
• Delivers strong drive capability with outputs capable of sourcing and sinking 24 mA.

Buffers, Drivers, Receivers, Transceivers Applications

• Memory and address drivers
• Clock drivers
• Bus-oriented transmitter/receivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and shipping configuration. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing standards. Cross-reference the datasheet revision number to guarantee alignment with the latest electrical specifications and mechanical dimensions before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a non-inverting octal buffer with three-state control is required for high-density board layouts. The ACT series is appropriate for systems requiring TTL-compatible input thresholds. Consider the SOIC-20 package constraints regarding thermal dissipation and physical footprint relative to alternative packages like TSSOP-20 or MC-prefix variants.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AC/ACT541 family of octal buffers and line drivers manufactured by onsemi. It serves as a functional equivalent to similar devices like the 74AC244 and 74ACTC244 but utilizes a distinct pinout arrangement. The 'SC' designation specifically identifies the SOIC-20 surface-mount package variant within the broader product line.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The MC74ACT541SC is a verified substitute part number offering identical functionality and pinout compatibility. Other members of the 74AC/ACT541 family may serve as alternatives depending on specific voltage or speed requirements, provided the package and logic polarity match the design needs.
