Product details

IO-Link physical-layer interface for 24V industrial sensor networks

The Maxim Integrated MAX14821ETG+ is a single-channel IO-Link transceiver designed for the physical layer of industrial sensor and actuator interfaces. The part operates from a 9V to 36V supply rail, covering the standard 24V industrial bus with headroom for transients, and is rated over the -40°C to 85°C industrial temperature range.

Package and layout: 24-TQFN with exposed pad

The pad is electrically connected to ground on the die.

Frequently asked questions

Is MAX14821ETG+ obsolete or active?

The MAX14821ETG+ is Active per Maxim's product status, with no end-of-life notice issued. It is suitable for new designs and production BOMs.

What is the data rate of MAX14821ETG+?

The MAX14821ETG+ supports a data rate of 230.4 kbps, which corresponds to the IO-Link COM2 speed class.

Does MAX14821ETG+ require an external regulator?

The MAX14821ETG+ operates directly from the 9V to 36V supply rail and includes an internal regulator for the transceiver core. No external regulator is needed for the transceiver itself, but the microcontroller-side logic supply (typically 3.3V or 5V) must be provided separately.
