FEATURES  
DESCRIPTION  
The DS3695A and DS3696A are high speed  
2
Meets EIA Standard RS485 for Multipoint Bus  
Transmission and is Compatible with RS-422  
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.  
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  
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.  
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  
Both AC and DC specifications are guaranteed over  
the 0°C to 70°C temperature and 4.75V to 5.25V  
supply voltage range.  
70 mV Typical Receiver Hysteresis  
Available in SOIC Packaging
