description
The SN75C188 is a monolithic, low-power, quadruple line driver that interfaces data terminal equipment with
data communications equipment. This device is designed to conform to ANSI Standard EIA / TIA-232-E.
An external diode in series with each supply-voltage terminal is needed to protect the SN75C188 under certain
fault conditions to comply with EIA / TIA-232-E.
The SN75C188 is characterized for operation from 0°C to 70°C.
