Product Summary

The DS36C278N is a low power differential bus/line transceiver designed to meet the requirements of RS-485 standard for multipoint data transmission. In addition it is compatible with TIA/EIA-422-B. The CMOS design of the DS36C278N offers significant power savings over its bipolar and ALS counterparts without sacrificing ruggedness against ESD damage. The device is ideal for use in battery powered or power conscious applications. ICC is specified at 500μA maximum. The DS36C278N driver and receiver outputs feature TRI-STATE capability. The driver outputs operate over the entire common mode range of -7V to +12V. Bus contention or fault situations that cause excessive power dissipation within the DS36C278N are handled by a thermal shutdown circuit, which forces the driver outputs into the high impedance state.

Parametrics

DS36C278N absolute maximum ratings: (1)Supply Voltage (VCC): +12V; (2)Input Voltage (DE, RE*, & DI): -0.5V to (VCC +0.5V); (3)Common Mode (VCM) Driver Output/Receiver Input: ±15V; (4)Input Voltage (DO/RI, DO*/RI*): ±14V; (5)Receiver Output Voltage: -0.5V to (VCC +0.5V); (6)Maximum Package Power Dissipation @ +25℃: 9.5 mW/℃; (7)Storage Temperature Range: -65 to +150℃; (8)Lead Temperature (Soldering 4 sec): +260℃.
