74ACT541SCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACT541SCX 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. The device provides non-inverting logic with TTL-compatible inputs. Electrical characteristics include a maximum quiescent supply current of 40 µA at 5.5 V and output drive capabilities of 24 mA for both sourcing and sinking. Propagation delay is specified at 7 ns at 5 V. The component supports an operating temperature range from -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features flow-through architecture with inputs and outputs positioned on opposite sides of the package to facilitate microprocessor interface and PCB layout density.
• Provides three-state outputs that allow switching between high, low, and high-impedance states to isolate signals from the bus when not enabled.
• Includes TTL-compatible inputs enabling direct interfacing with TTL logic circuits.

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

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'SCX' corresponds to the SOIC-20 tape and reel configuration containing 1000 units per reel as documented in the manufacturer's ordering information. Confirm RoHS compliance status and lead-free packaging details through official datasheets or supplier documentation prior to finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a non-inverting octal buffer with three-state capability is required for 5V logic systems. The ACT series offers TTL-compatible input thresholds suitable for mixed logic environments. Ensure the application requires the specific flow-through pinout arrangement beneficial for microprocessor port expansion and board density optimization.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACT541 family of octal buffers and line drivers manufactured by onsemi. It serves as the non-inverting counterpart to the 74AC540 and shares functional similarities with the 74AC244 and 74ACTC244 families, distinguished primarily by its specific flow-through pinout design intended for enhanced layout flexibility.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The MC74ACT541DWG is a confirmed substitute part number offering identical functionality in a 20-SOIC package. Verify pin compatibility and electrical specifications against the primary datasheet before implementation.
