MAX14770E: Industry's Highest ESD-Protected Profibus-DP Transceiver
- click to enlarge
The MAX14770E is a half-duplex, ±35kV HBM high ESD-protected 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 operates from a +5V supply and has true fail-safe circuitry that guarantees a logic-high receiver output when the receiver inputs are open or shorted.
The MAX14770E features a 1/4 standard-unit load receiver input impedance, allowing up to 128 1/4 unit load transceivers on the bus. Drivers are short-circuit current limited and are protected against excessive power dissipation by thermal-shutdown circuitry.
The MAX14770E is available in 8-pin SO and tiny TDFN (3mm x 3mm) packages, and is specified over the extended (-40°C to +85°C) and automotive (-40°C to +125°C) temperature ranges.
