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.

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
70 mV Typical Receiver Hysteresis
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.
Both AC and DC specifications are specified over the
0°C to 70°C temperature and 4.75V to 5.25V supply
voltage range.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
