DS3695, DS3695T, DS3696, DS3697 www.ti.com SNLS072C – MAY 1998 – REVISED APRIL 2013 Multipoint RS485/RS422 Transceivers/Repeaters Check for Samples: DS3695, DS3695T, DS3696, DS3697 FEATURES DESCRIPTION • 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. 1 2 • • • • • • • Meets EIA standard RS485 for Multipoint Bus Transmission and is Compatible with RS-422 15 ns Driver Propagation Delays with 2 ns Skew (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 TRISTATE 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 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.
