Quad CMOS Receiver

DS14C89A/DS14C89AT Quad CMOS Receiver

February 1996

General Description

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.

Note 1: ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The tables of ‘‘Electrical Characteristics’’ specify conditions for device operation.
