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.
