DESCRIPTION

The DS90C032 is a quad CMOS differential line

receiver designed for applications requiring ultra low

power dissipation and high data rates.

The DS90C032 accepts low voltage differential input

signals and translates them to CMOS (TTL compatible) output levels. The receiver supports a

TRI-STATE function that may be used to multiplex

outputs. The receiver also supports OPEN Failsafe

and terminated (100Ω) input Failsafe with the addition

of external failsafe biasing. Receiver output will be

HIGH for both Failsafe conditions.

The DS90C032 provides power-off high impedance

LVDS inputs. This feature assures minimal loading

effect on the LVDS bus lines when VCC is not

present.

The DS90C032 and companion line driver

(DS90C031) provide a new alternative to high power

pseudo-ECL devices for high speed point-to-point

interface applications.
