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.

DS011106
See NS Package Number M14A, N14A
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
