STMicroelectronics | ST485CDR

The ST485CDR is a low power transceiver for RS-485 and RS-422 communication, available in surface mount SOIC-8 package.

This device is designed for bi-directional data communications on multipoint bus transmission line (half-duplex applications). The ST485 is available in three temperature range: commercial (0 °C to 70 °C), industrial (-40 °C to 85 °C) and automotive (-55 °C to 125 °C).

Features:

• Low quiescent current: 300 μA
• Designed for RS-485 interface application
• - 7 V to 12 V common mode input voltage range
• Driver maintains high impedance in 3-state or with the power OFF
• 70 mV typical input hysteresis
• 30 ns propagation delay, 5 ns skew
• Operate from a single 5 V supply
• Current limiting and thermal shutdown for driver overload protection
• Allows up to 64 transceivers on the bus
