DS14C89A/DS14C89AT Quad CMOS Receiver General Description Features The DS14C89A/DS14C89AT, pin-for-pin compatible to the DS1489A/MC1489A, are receivers 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 mA (DS14C89A) versus 26 mA (DS1489A). The DS14C89A/DS14C89AT provide on chip noise filtering which eliminates the need for external response control filter capacitors. When replacing the DS1489A with the DS14C89A/DS14C89AT, the response control filter pins can be tied high, low, or not connected.
