The DS3695, DS3696, and DS3697 are high speed differential TRI-STATE bus/line
transceivers/repeaters designed to meet the requirements of EIA standard RS485 with extended common
mode range (+12V to −7V), for multipoint data transmission.
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 DS3696 provides an output pin TS (thermal shutdown)
which reports the occurrence of the thermal shutdown of the device. This is an “open collector” pin
with an internal 10 kΩ pull-up resistor. This allows the line fault outputs of several devices to
be wire OR-ed.
Both AC and DC specifications are specified over the 0°C to 70°C temperature and 4.75V to
5.25V supply voltage range.
