MAX14770EESA+

The MAX14770EESA+ is a ±35KV high ESD profibus RS 485 transceiver in 8 pin NSOIC package. This is a half-duplex, 20Mbps transceiver for PROFIBUS-DP and RS 485 applications. In addition, it can be used for RS-422/V.11 communications. IC is designed to meet IEC 61158-2, TIA/EIA-422-B, TIA/EIA- 485-A, V.11 and X.27 standards. Device features true fail-safe circuitry that gives a logic high receiver output when receiver inputs are open or shorted or when they are connected to a terminated transmission line with all drivers disabled. Drivers are output short circuit current limited. Thermal shutdown circuitry protects drivers against excessive power dissipation. When activated thermal shutdown circuitry places driver outputs into a high impedance state. It has a hot swap input structure that prevents disturbances on the differential signal lines when IC is powered up. It is used in PROFIBUS-DP networks, industrial fieldbuses, motion controllers, RS 485 networks and machine encoders.
