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.

•

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

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.

•

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 specified over the

0°C to 70°C temperature and 4.75V to 5.25V supply

voltage range.
