MC1489AN
Quadruple Line Receiver 14-PDIP 0 to 70
Thresholds) Response Control that Provides:
Input Threshold Shifting
Input Noise Filtering Meet or Exceed the Requirements of
TIA/EIA-232-F and ITU Recommendation
V.28 Fully Interchangeable With Motorola
MC1489 and MC1489A
descriptionThese devices are monolithic low-power Schottky
quadruple line receivers designed to satisfy the
requirements of the standard interface between
data-terminal equipment and data-communica-
tion 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.
