DS14C89A www.ti.com SNLS081C – MAY 1998 – REVISED APRIL 2013 DS14C89A Quad CMOS Receiver Check for Samples: DS14C89A FEATURES 1 •2 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 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). 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. Connection Diagram Figure 1.
