The MAX14783E is a 3.3V/5V ESD-protected transceiver intended for half-duplex RS-485/RS-422 communication up to 42Mbps. The device is optimized for high speeds over extended cable runs while maximizing tolerance to noise.
The MAX14783E integrated protection features include short-circuit-protected outputs, hot-swap functionality, and a true fail-safe receiver, guaranteeing a logic-high receiver output when inputs are shorted or open. Hotswap capability eliminates undesired transitions on the bus during power-up or hot insertion.
The transceiver draws 1.9mA (typ) supply current when unloaded or when fully loaded with the drivers disabled and draws less than 10µA (max) of supply current in low-power shutdown mode.
The MAX14783E is available in 8-pin µMAX, 8-pin SO, and small, 8-pin (3mm x 3mm) TDFN-EP packages. The device in the TDFN-EP package operates over the -40°C to +125°C temperature range. The MAX14783E in the µMAX and SO packages operates over the -40°C to +85°C and -40°C to +125°C temperature ranges.
