Multipoint RS485/RS422 Transceivers/Repeaters
General Description
The DS3695, DS3696, and DS3697 are high speed differ-
ential TRI-STATE
to meet the requirements of EIA standard RS485 with ex-
tended common mode range (+12V to −7V), for multipoint
data transmission.
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 kΩ pull-up resistor. This allows the line
fault outputs of several devices to be wire OR-ed.
Both AC and DC specifications are guaranteed over the 0˚C
to 70˚C temperature and 4.75V to 5.25V supply voltage
range.
Connection and Logic Diagrams
Note 1: TS pin was LF (Line Fault) in previous datasheets and reports the occurrence of a thermal shutdown of the device.
