TECHNICAL DATA
Qudruple Line Receivers
The KK1489A is a monolithic quadruple line receivers designed to satisfy the requirements of the standard interface between data terminal equipment and data munication equipments as defined by EIA standard RS-232C. A separate response control terminal is provided for each receiver. A resistor or a resistor and bias voltage can be connected between this terminal and ground to shift the input threshold voltage levels. An external capacitor can be connected from this terminal to ground to provide input noise filtering.
- Input Resistance ... 3 kΩ to 7kΩ
