DS75176B Datasheet | National Semiconductor

Description The DS75176B is a high speed differential TRI-STATE ® bus/line transceiver designed to meet the requirements of EIA standard RS485 with extended mon mode range (+12V to - 7V), for multipoint data transmission. In addition, it is patible with RS-422. The driver and receiver outputs feature TRI-STATE capability, for the driver outputs over the entire mon 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. Features n Meets EIA standard RS485 for multipoint bus transmission and is patible with RS-422. n Small Outline (SO) Package option available for minimum board space. n 22 ns driver propagation delays. n Single +5V supply. n - 7V to +12V bus mon mode range permits ± 7V ground difference between devices on the bus. n Thermal shutdown protection. n High impedance to bus with driver in TRI-STATE or with power off, over the entire mon mode range allows the unused devices on the bus to be powered down. n Pin out patible with DS3695/A and SN75176A/B. n bined impedance of a driver output and receiver input is less than one RS485 unit load, allowing up to 32 transceivers on the bus. n 70 m V typical receiver hysteresis.
