DS14C89A
Description
The DS14C89A DS14C89AT pin-for-pin patible 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 pared 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.
