MAX14770EESA+

MAX14770EESA+ 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/EIA485-A, V.11, and X.27 standards. Applications include PROFIBUS-DP networks, industrial fieldbuses, motion controllers, RS-485 networks, and machine encoders.

• True fail-safe receiver prevents false, transitions on receiver input short or open
• Hot swap eliminates false transitions during power-up or hot insertion
• Short-circuit-protected outputs
• Thermal shutdown circuitry prevents excessive power dissipation
• Low current reduces power consumption
• Allows up to 128 transceivers on the bus
• Power-supply range from 4.5 to 5.5V
• Shutdown supply current is 15µA max at DE=0, active-low RE=1
• 8 SO package
• Temperature range from -40°C to +85°C
