Product Summary

The DS485TN is a low-power transceiver for RS-485 and RS-422 communication. The device contains one driver and one receiver. The drivers slew rate allows for operation up to 2.5 Mbps. The transceiver draws 200 µA of supply current when un-loaded or fully loaded with the driver disabled and operates from a single +5V supply.

Parametrics

DS485TN absolute maximum ratings: (1)supply Voltage (VCC) +12V; (2)Enable Input Voltage: -0.5V to (VCC + 0.5V); (3)Driver Input Voltage (DI): -0.5V to (VCC + 0.5V); (4)Driver Output Voltage (A, B): -14V to +14V; (5)Receiver Input Voltage (A, B): -14V to +14V; (6)Receiver Output Voltage (RO): -0.5V to (VCC + 0.5V); (7)Maximum Package Power Dissipation: 0.76W; (8)Storage Temperature Range: -65℃ to +150℃.

Features

DS485TN features: (1)Meets TIA/EIA RS-485 multipoint standard; (2)Guaranteed full load output voltage; (3)Low quiescent current: 200 μA typ; (4)?7V to +12V common-mode input voltage range; (5)TRI-STATE outputs on driver and receive; (6)Half-duplex flow through pinout; (7)Operates from a single 5V supply; (8)Allows up to 32 transceivers on the bus; (9)Current-limiting and thermal shutdown for driver overload protection; (10)Industrial temperature range operation; (11)Pin and functional compatible with MAX485 and LTC485.
