DS14C89A Quad CMOS Receiver General Description 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). When replacing the DS1489A with the DS14C89A, the response control filter pins can be tied high, low, or not connected. Features n n n n n Meets EIA/TIA-232-E and CCITT V.28 Standards Failsafe - Output High for Open Input LOW Power consumption On chip noise filter Available in SOIC Package The DS14C89A provides on chip noise filtering which eliminates the need for external response control filter capacitors.
