LVDS Quad CMOS Differential Line Driver
General Description
The DS90C031 is a quad CMOS differential line driver designed for applications requiring low power dissipation and high data rates. The DS90C031 accepts TTL/CMOS input levels and translates them to low voltage (350 mV) differential output siginals. 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. The DS90C031 and companion line receiver (DS90C032) provide a new alternative to high power pseudo-ECL devices for high speed point-to-point interface applications.

Note 2:
Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the device should be operated at these limits. The table of "Electrical Characteristics" provides conditions for actual device operation. Derate (E Pkg) @ 12.8mW/C above +25C. Derate (W Pkg) @ 6.9 mW/C above +25C.
