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 may 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/us 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 us. 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.
