MAX14819ATM+T

Drivers, Receivers, Transceivers Overview

The MAX14819ATM+T is a dual-channel IO-Link master transceiver with integrated framers and L+ supply controllers. It operates on a VCC supply of 9V to 36V and features a total typical supply current of 1.9mA for two channels. The device includes two auxiliary digital inputs, supports NPN sensors, and provides reverse polarity protection and overvoltage tolerance on all interface pins. It is specified over an operating temperature range of -40°C to +125°C and is housed in a 48-pin (7mm x 7mm) TQFN package.

• IO-Link Gateways

Drivers, Receivers, Transceivers Procurement Notes

Verify that the suffix 'T' indicates tape-and-reel packaging rather than tray packaging. Confirm RoHS compliance status through official documentation. Ensure the component matches the specific MAX14819 variant required for the design, as electrical characteristics may differ between versions.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing dual-channel IO-Link master nodes requiring integrated framing and power management. Consider the MAX14819A variant if higher L+ thresholds or increased high-frequency signal isolation are necessary. Verify SPI interface compatibility with the host microcontroller.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX14819 series of low-power, dual-channel IO-Link master transceivers. The series is designed to simplify time-critical control of IO-Link M-sequence frame types through integrated frame handlers with UARTs and FIFOs.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX14819A is a related variant within the same family offering higher L+ thresholds and improved high-frequency signal isolation. Verify pinout and register compatibility before substitution.
