description
The SN75155 monolithic line driver and receiver is designed to satisfy the requirements of the standard
interface between data terminal equipment and data communication equipment as defined by ANSI
EIA/TIA-232-E. A response control input is provided for the receiver. A resistor or a resistor and a bias voltage
can be connected between the response control input and ground to provide noise filtering. The driver used is
similar to the SN75188. The receiver used is similar to the SN75189A.
The SN75155 is characterized for operation from 0°C to 70°C.
