Features • Meets EIA standard RS485 for multipoint bus transmission and is compatible with RS-422 • 10 ns driver propagation delays (typical) • 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 • 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 • Available in SOIC packaging Description The DS3695A and DS3696A are high speed differential TRI-STATE® bus/line transceivers designed to meet the requirements of EIA standard RS485 with extended common mode range (+12V to -7V), for multipoint data transmission. In addition they are compatible with requirements of RS-422. The driver and receiver outputs feature TRI-STATE capability. The driver outputs remain in TRI-STATE® over the entire common mode range of +12V to -7V. Bus faults that cause excessive power dissipation within the device trigger a thermal shutdown circuit, which forces the driver outputs into the high impedance state. The DS3696A provides an output pin (TS) which reports the thermal shutdown of the device. TS is an "open collector" pin with an internal 10 k pull-up resistor. This allows the TS outputs of several devices to be wire OR-ed. Both AC and DC specifications are guaranteed over the 0°C to 70°C temperature and 4.75V to 5.25V supply voltage range.
