MAX14784E:Full-Duplex, ±35kV ESD-Protected, RS-485 Transceivers for High-Speed Communication

Reduce Field Failures with Highest ESD Dual Voltage Full Duplex RS-485 Transceivers

The MAX14784E/MAX14786E/MAX14787E/MAX14789E full-duplex RS-485 transceivers are designed for robust communication in harsh industrial environments. All devices feature ±35kV ESD protection on the RS-485 pins and operate from a 3V to 5.5V supply with a 4mA no-load supply current (max). The MAX14784E/MAX14787E are optimized for communication over very long cables or short unterminated cables. The MAX14784E/MAX14786E are available in a 14-pin SO package and and operate over the -40°C to +125°C temperature range. The MAX14786E is also available in a 14-pin TSSOP package. The MAX14787E/MAX14789E are optimized for space-constrained applications and are available in an 8-pin SO package and operate over the -40°C to +105°C temperature range.
