Product Details
MAX22194ATJ+ - Quad Industrial Sink/Source Digital Input
MAX22194ATJ+ from Analog Devices Inc. / Maxim Integrated is a four-channel configurable industrial digital-input interface with diagnostics, glitch filtering and SPI control in a 32-pin TQFN.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
MAX22194 provides four independently configurable sink or source digital-input channels with current limiting, field-side diagnostics, programmable filtering and an SPI interface.
Key Advantages
Each input supports sink or source operation and IEC 61131-2 type 1, type 2, type 3, TTL or high-impedance modes.
Integrated diagnostics, glitch filters and a 5 V regulator simplify dense industrial input modules.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
