Features Meets EIA standard RS485 for multipoint bus transmission and is compatible with RS-422. Small Outline (SO) Package option available for minimum board space. 22 ns driver propagation delays. Single +5V supply. -7V to +12V bus common mode range permits ±7V ground difference between devices on the bus. Thermal shutdown protection. High impedance to bus with driver in TRI-STATE or with power off, over the entire common mode range allows the unused devices on the bus to be powered down. Pin out compatible with DS3695/A and SN75176A/B. Combined impedance of a driver output and receiver input is less than one RS485 unit load, allowing up to 32 transceivers on the bus. 70 mV typical receiver hysteresis. Description The DS75176B is a high speed differential TRI-STATE® bus/line transceiver designed to meet the requirements of EIA standard RS485 with extended common mode range (+12V to -7V), for multipoint data transmission. In addition, it is compatible with RS-422. The driver and receiver outputs feature TRI-STATE capability, for the driver outputs over the entire common mode range of +12V to -7V. Bus contention or fault situations that cause excessive power dissipation within the device are handled by a thermal shutdown circuit, which forces the driver outputs into the high impedance state. DC specifications are guaranteed over the 0 to 70°C temperature and 4.75V to 5.25V supply voltage range.
