DS14C89A DS14C89AT
Quad CMOS Receiver
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 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 mA
(DS14C89A) versus 26 mA (DS1489A)
The DS14C89A DS14C89AT provide on chip noise filtering
which eliminates the need for external response control fil-
ter capacitors When replacing the DS1489A with the
DS14C89A DS14C89AT the response control filter pins
can be tied high low or not connected
Features
Y Meets EIA TIA-232-E and CCITT V 28 Standards
Y Industrial Temperature Range
b40 C to a85 C – DS14C89AT
Y LOW Power consumption
Y On chip noise filter
Y Available in SOIC Package
