TECHNICAL DATA

IN1489A

Qudruple Line Receivers

The IN1489A 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.
