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
The driver and receiver outputs feature TRI-STATE capability. The driver outputs remain
in 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 kΩ 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.
