Maxim offers a wide selection of interface ICs. Their portfolio includes circuits for interconnection, signal translation, voltage protection, current protection, and electrical isolation. Simplify project designs while also making it more robust and reliable with their transceivers, IO-Link transceivers and binary drivers, controllers and expanders, level translators, industrial digital I/Os, broadband switches, and ICs for isolation, high-speed signaling, universal serial bus (USB), signal line protection, signal integrity, and 4 mA to 20 mA current loops.

An example of an interface IC that delivers high electrostatic discharge (ESD) protection for industrial end equipment is their MAX3483AE family. These ±20 kV ESD-protected RS-485/422 transceivers are optimized for extended cable runs in noisy environments. All of them operate from a single 3.3 V supply. Also useful for industrial control, as well as instrumentation, lighting, and security systems, are their MAX13089E ESD-protected, fail-safe, hot-swap RS-485/422 transceivers. In this transceiver family are circuits with reduced slew-rate drivers that minimize electromagnetic interference (EMI) and reduce reflections from improperly terminated cables, as well as circuits that support a range of data transmission speeds.
