High-Speed 3.3V/5V RS-485 Transceiver with ±35kV HBM ESD Protection

The MAX14783E is a half-duplex RS-485 transceiver that operates at either 3.3V or 5V rails with high ±35kV ESD performance and up to 42Mbps data rate. The device is optimized for high speeds over extended cable runs while maximizing tolerance to noise.

The MAX14783E is available in 8-pin µMAX®, 8-pin SO, and 8-pin 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.
