Overview

DS90C031B LVDS Quad CMOS Differential Line Driver March 1999 DS90C031B LVDS Quad CMOS Differential Line Driver General Description The DS90C031B is a quad CMOS differential line driver designed for applications requiring ultra low power dissipation and high data rates.
The device is designed to support data rates in excess of 155.
5 Mbps (77.
7 MHz) utilizing Low Voltage Differential Signaling (LVDS) technology.
The DS90C031B 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, disabling the load current, and thus dropping the device to an ultra low idle power state of 11 mW typical.
In addition, the DS90C031B provides power-off high impedance LVDS outputs.
This feature assures minimal loading effect on the LVDS bus lines when VCC is not present.
The DS90C031B and companion line receiver (DS90C032B) provide a new alternative to high power pseudo-ECL devices for high speed point-to-point interface applications.
