MC1489 and MC1489A

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-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.
