IN1489A
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
