Maxim’s expanded portfolio of IEC61131-2 compliant digital input devices offers one of the industry’s smallest solution sizes (by as much as 50%), low power dissipation (by as much as 60% when compared to similar products) up to 6 times faster than industry alternatives, and very robust performance (integrating 1 kV of surge and integrated diagnostics). These input devices are well-suited for designers of industrial equipment striving to meet the size, power, and performance requirements of industry 4.0 applications.

MAX22190: 8-channel octal digital input with serial peripheral interface (SPI), accurate input current limiters, built-in surge protection of >1 kV, and wire break detection in a 5 mm x 5 mm package

MAX22191: Single-channel, parasitically powered digital input with accurate input current limiters and 250 ns propagation delay in a 2.8 mm x 2.9 mm package

MAX22192: 8-channel octal digital input with isolated SPI, fast/safe demagnetization, wire break detection, and accurate input current limiters in a 9.7 mm x 5.3 mm package

MAX22195: High-speed, octal digital input with parallel output and accurate input current-limiters, 300 ns (typ) propagation delay parallel interface, low power and low heat dissipation, fault tolerance with built-in diagnostics, configurability, and a robust design in a 5 mm x 5 mm 32-TQFN package
