74ACT541MTCX

Buffers, Drivers, Receivers, Transceivers Overview

The MC74ACT541MTCX is an octal buffer and line driver manufactured by onsemi, belonging to the 74ACT logic family. It features non-inverting outputs with three-state capability, allowing high-impedance isolation when disabled. The device 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. It provides strong output drive capabilities, sourcing and sinking up to 24 mA per pin. The component utilizes a flow-through architecture with inputs and outputs positioned on opposite sides of the package, facilitating efficient printed circuit board layout.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'MTCX' corresponds to the TSSOP-20 tape and reel packaging configuration. Confirm the device marking matches the ACT541 identifier. Ensure the procurement specification aligns with the required 4.5 V to 5.5 V operating voltage range and industrial temperature limits.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a non-inverting octal buffer with three-state control is required for microprocessor interfaces. The flow-through architecture simplifies PCB routing compared to parallel input/output layouts. Verify compatibility with TTL logic levels if interfacing with legacy systems, as the ACT series ensures direct compatibility without additional level shifting.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACT541 series of octal buffers and line drivers. It serves as the non-inverting counterpart to the inverting 74ACT540 model. The device shares functional similarities with the 74AC244 and 74ACTC244 families but distinguishes itself through its specific flow-through pinout design optimized for high-density board layouts.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the function of the OE1 and OE2 pins?

OE1 and OE2 are active-low output enable inputs. When either pin is at a low logic level, the corresponding outputs are enabled. If both are high, all outputs enter a high-impedance state.

How does the flow-through architecture benefit PCB design?

The flow-through architecture places inputs on one side of the package and outputs on the opposite side. This arrangement allows signals to pass directly through the device, reducing trace length and simplifying routing for microprocessor port expansions.
