Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type, temperature grade, and reel specifications. Confirm that the VIO pin configuration matches the target system's logic voltage requirements. Ensure thermal management aligns with the specified junction-to-ambient resistance values for the selected PCB layout.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex communication is required alongside high-speed data rates up to 50 Mbps. The inclusion of a dedicated VIO pin allows for flexible interfacing with lower voltage logic controllers while maintaining standard RS-485 bus levels. Verify compatibility with PROFIBUS standards if operating at VCC voltages greater than or equal to 4.5 V.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ADM306xE series of RS-485 transceivers designed for robust industrial environments. The series differentiates models based on duplex mode, data rate capabilities, and the presence of a VIO logic supply pin. The ADM3068E specifically provides full-duplex functionality with high-speed performance and flexible logic interfacing options.

Drivers, Receivers, Transceivers FAQ

Does the ADM3068E support PROFIBUS?

Yes, the ADM3068E is PROFIBUS compliant when the VCC supply voltage is greater than or equal to 4.5 V.

What is the purpose of the VIO pin?

The VIO pin provides a separate logic supply input, allowing the digital interface to operate independently from the main VCC supply, with a minimum operating voltage of 1.62 V.

How many transceivers can be connected to the bus?

The device features a 1/4 unit load input impedance, which allows for the connection of up to 128 transceivers onto a single bus.
