Check for Samples: DS3695A, DS3695AT, DS3696A FEATURES DESCRIPTION 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 RS-422. 1 2 Meets EIA Standard RS485 for Multipoint Bus
Transmission and is Compatible with RS-422
10 Ns Driver Propagation Delays (Typical)
Single +5V Supply
-7V to +12V Bus Common Mode Range
Permits В±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
