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.
