SN75C188 Description
The SN75C188 is a monolithic, low-power, quadruple line driver that interfaces data terminal equipment with data munications 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 ply with EIA / TIA-232-E.
