DS14C89A Quad CMOS Receiver

Check for Samples: DS14C89A

FEATURES

DESCRIPTION

The DS14C89A, pin-for-pin compatible to the

• Meets EIA/TIA-232-E and CCITT V.28

DS1489A/MC1489A, ia a quad receiver designed to

Standards

interface data terminal equipment (DTE) with data

• Failsafe - Output High for Open Input

circuit-terminating equipment (DCE). These devices

• LOW Power Consumption

translate levels conforming to EIA-232E and CCITT

V.28 standards to TTL/CMOS logic levels.

• On Chip Noise Filter

The device is fabricated in low threshold CMOS metal

• Available in SOIC Package

gate technology. The device provides very low power

consumption compared to their bipolar equivalents:

900 μA (DS14C89A) versus 26 mA (DS1489A).

The DS14C89A provides on chip noise filtering which

eliminates the need for external response control filter

capacitors. When replacing the DS1489A with the

DS14C89A, the response control filter pins can be

tied high, low, or not connected.
