1 / 5 page 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 conform- ing 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 consump- tion compared to their bipolar equivalents: 900 µA (DS14C89A) versus 26 mA (DS1489A). The DS14C89A provides on chip noise filtering which elimi- nates the need for external response control filter capacitors. When replacing the DS1489A with the DS14C89A, the re- sponse control filter pins can be tied high, low, or not con- nected. Features n Meets EIA/TIA-232-E and CCITT V.28 Standards n Failsafe - Output High for Open Input n LOW Power consumption n On chip noise filter n Available in SOIC Package Connection Diagram 01110601 Order Number DS14C89AN, DS14C89AM, See NS Package Number M14A, N14A May 1998 © 2004 National Semiconductor Corporation DS011106 www.national.com |
