MAX22193ATP+

Specialized Overview

The MAX22193ATP+ is a high-speed, quad industrial digital input device with parallel outputs. It translates four 24V field inputs into CMOS-compatible logic signals with a maximum propagation delay of 300ns and channel-to-channel skew of 40ns. The device operates from a 7V to 65V field supply (VDD24) or an external 3.0V to 5.5V supply (VDD3). It features configurable IEC 61131-2 Type 1, 2, and 3 inputs via a current-setting resistor, energyless LED drivers, and integrated overtemperature and voltage monitoring. Packaged in a 4mm x 4mm 20-TQFN.
