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.
