TECHNICAL DATA
KK1489A
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 communication 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.
