General Description  
Features  
n Meets EIA standard RS485 for multipoint bus  
The DS3695, DS3696, and DS3697 are high speed differen-  
tial 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.  
transmission and is compatible with RS-422  
n 15 ns driver propagation delays with 2 ns skew (typical)  
n Single +5V supply  
±
n −7V to +12V bus common mode range permits 7V  
The driver and receiver outputs feature TRI-STATE capabil-  
ity. 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 ther-  
mal 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 kpull-up resistor. This allows the line  
fault outputs of several devices to be wire OR-ed.  
ground difference between devices on the bus  
n Thermal shutdown protection  
n 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  
n Combined impedance of a driver output and receiver  
input is less than one RS485 unit load, allowing up to 32  
transceivers on the bus  
n 70 mV typical receiver hysteresis  
Both AC and DC specifications are guaranteed over the 0˚C  
to 70˚C temperature and 4.75V to 5.25V supply voltage  
range.
