QudrautpalSe hLeineet4RUe.cceoimversThe IN1489A is a monolithic quadruple line receivers designed to
.Dsatisfy the requirements of the standard interface between data terminal
wequipment and data communication equipments as defined by EIA
standard RS-232C. A separate response control terminal is provided for
wweach 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.
mInput Resistance ... 3 kto 7k
Input Signal Range ... ±30 V
oOperates from Single 5 V Supply
