75189 Quad Line Receiver RS232 is a monolithic low-power Schottky quadruple line receiver designed to satisfy the requirements of the standard interface between data terminal equipment and data-communication equipment. A separate response-control (CONT) terminal is provided for each receiver. A resistor or a resistor and bias-voltage source can be connected between this terminal and ground to shift the input threshold levels. An external capacitor can be connected between this terminal and the ground to provide input noise filtering.
The SN55189A is characterized for operation over the full military temperature range of –55°C to 125°C. The MC1489, MC1489A, SN75189, and SN75189A are characterized for operation from 0°C to 70°C.
