description
These devices are monolithic low-power Schottky
quadruple line receivers designed to satisfy the
requirements of the standard interface between
data-terminal equipment and data-communication equipment as defined by TIA / EIA-232-F. A
separate response-control (CONT) terminal is
provided for each receiver. A resistor or a resistor
and bias-voltage source can be connected
between this terminal and ground to shift the input
threshold levels. An external capacitor can be
connected between this terminal and ground to
provide input noise filtering.
The SN55189 and SN55189A are characterized
for operation over the full military temperature
range of – 55°C to 125°C. The MC1489,
MC1489A, SN75189, and SN75189A are
characterized for operation from 0°C to 70°C.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
