About this product
SN75189N is a quad RS-232 line receiver from Texas Instruments that converts TIA/EIA-232-F voltage levels to logic levels for serial communication between data terminal and data communication equipment. Each receiver has a response-control terminal that shifts the input threshold or filters noise using an external resistor or capacitor. It comes in a 14-pin PDIP package.

Does the SN75189N also transmit data?
No. It is a receiver only. To transmit RS-232 signals, pair it with a driver such as the SN75188, or use a transceiver such as a MAX232-type IC.
How do I adjust the input threshold or filter noise?
Connect the CONT terminal of each receiver to ground through a resistor, or through a resistor and a bias voltage source, to shift the threshold. Connect a capacitor from CONT to ground to filter input noise, as described in the datasheet.
