MAX14770E

±35kV High-ESD PROFIBUS RS-485 Transceiver

Industry's Highest ESD-Protected PROFIBUS-DP Transceiver


Please check latest availability status for a specific part variant.

Description

The MAX14770E is a half-duplex, ±35kV high ESD-protected, 20Mbps transceiver for PROFIBUS-DP and RS-485 applications. In addition, it can be used for RS-422/V.11 communications. The MAX14770E is designed to meet IEC 61158-2, TIA/EIA-422-B, TIA/EIA-485-A, V.11, and X.27 standards.

The MAX14770E is available in an 8-pin SO and an 8-pin µMAX® specified over the extended temperature range. It is also available in a tiny TDFN (3mm x 3mm) package and specified over the automotive (-40°C to +125°C) temperature range.
