MAX22195ATJ+

Sensor And Detector Interfaces Overview

The MAX22195ATJ+ is an octal industrial digital input device that translates eight 24V field signals into parallel CMOS outputs. It operates from a VDD24 supply ranging from 7V to 65V or an external VDD3 supply between 3.0V and 5.5V. The device features a maximum propagation delay of 300ns and channel-to-channel skew of ±10ns. It includes an integrated LDO regulator providing up to 25mA at 3.3V, configurable current limiters for IEC 61131-2 Types 1, 2, and 3 inputs, and energyless LED drivers. The component is housed in a 32-TQFN package.

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm RoHS compliance status and tape-and-reel packaging specifications. Ensure the selected variant matches the required operating temperature range and voltage ratings for the target application environment before finalizing procurement orders.

Sensor And Detector Interfaces Selection Notes

Select the appropriate REFDI resistor value to configure the input current limits for specific IEC 61131-2 types. For Type 2 applications requiring higher input currents, utilize two channels in parallel per input signal. Ensure adequate thermal management on the PCB ground plane to maintain operation within the specified ambient temperature limits under full load conditions.
