DESCRIPTION
The DS90C031 is a quad CMOS differential line
driver designed for applications requiring ultra low
power dissipation and high data rates.
The DS90C031 accepts TTL/CMOS input levels and
translates them to low voltage (350 mV) differential
output signals. In addition the driver supports a TRI-
STATE function that may be used to disable the
output stage, thus dropping the device to a low idle
power state of 11 mW typical.
In addition, the DS90C031 provides power-off high
impedance LVDS outputs. This feature assures
minimal loading effect on the LVDS bus lines when
VCC is not present. The DS90C031 and companion
line receiver (DS90C032) provide a new alternative to
high power psuedo-ECL devices for high speed pointto-
point interface applications.
