74ACTQ541SCX

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74ACTQ541SCX is an octal buffer and line driver featuring non-inverting 3-STATE outputs. It operates within a supply voltage range of 4.5 V to 5.5 V, with a typical propagation delay of 7 ns at 5 V. The device provides high drive capability, sourcing and sinking up to 24 mA per output while maintaining low static current consumption of 4 uA. Designed for surface-mount applications, it utilizes a 20-pin SOIC package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Flow-through architecture with inputs and outputs on opposite sides of the package to facilitate easier board layout and increased PC board density.
• Reduced ICC and IOZ power consumption by 50% compared to standard AC series devices.
• Guaranteed simultaneous switching noise levels and dynamic threshold performance for signal integrity.
• TTL-compatible inputs allowing direct interface with TTL logic systems.

Buffers, Drivers, Receivers, Transceivers Applications

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

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'SCX' against the manufacturer's official documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the datasheet revision date to confirm pinout consistency with existing designs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a flow-through pinout is required for microprocessor output ports to simplify PCB routing. Choose over standard 74AC541 variants if reduced power consumption and guaranteed simultaneous switching noise performance are critical design constraints. Verify that the 24 mA drive strength meets the load requirements of the destination circuitry.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACTQ (Quiet ACT) logic family, which combines the speed of ACT logic with low-noise characteristics. It serves as the octal counterpart to the hex driver 74ACTQ244, distinguished by its flow-through input/output arrangement rather than parallel alignment.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ACT541SCX is a functional equivalent within the standard ACT family but lacks the specific noise reduction features of the Q series. The MM74HC541MTCX offers similar functionality but operates at lower voltages and has different drive strengths.
