The DS14C89A, pin-for-pin compatible to the DS1489A/MC1489A, ia a quad receiver designed
to interface data terminal equipment (DTE) with data circuit-terminating equipment (DCE). These
devices translate levels conforming to EIA-232E and CCITT V.28 standards to TTL/CMOS logic
levels.
The device is fabricated in low threshold CMOS metal gate technology. The device provides
very low power consumption compared to their bipolar equivalents: 900 μA (DS14C89A) versus 26 mA
(DS1489A).
The DS14C89A provides on chip noise filtering which eliminates the need for external
response control filter capacitors. When replacing the DS1489A with the DS14C89A, the response
control filter pins can be tied high, low, or not connected.
