description

The SN75186 is a low-power bipolar device
containing four driver/receiver pairs designed to
interface data terminal equipment (DTE) with data
circuit-terminating equipment (DCE). Additionally ,
the SN75186 has a loopback mode that can be
used by a data communication system to perform
a functional self-test on each driver/receiver pair,
removing the need to locally disconnect cables
and install a loopback connector. Flexibility of
control is ensured by each driver/receiver pair
having its own loopback control input. The
SN75186 is designed to conform to standards
ANSI EIA/TIA-232-E and ITU Recommendation
V.28.

The maximum slew rate is limited to 30 V/µs at
the driver outputs, and the SN75186 drives a capacitive load of 2500 pF at 20 kBaud. The receivers have input
filters that disregard input noise pulses shorter than 1 µs. The SN75186 is a robust device capable of
withstanding ±30 V at driver outputs and at receiver inputs whether powered or unpowered. This device has
an internal ESD protection rated at 4 kV to prevent functional failures.

The SN75186 is characterized for operation from 0°C to 70°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTE 2: If all receiver inputs are held at ±30 V , the thermal dissipation limit of the package may be exceeded. The thermal shutdown may not

protect the device, as this dissipation occurs in the receiver input resistors.
