The DS90LV031A is a quad CMOS differential line driver utilizing Low Voltage Differentional Signaling (LVDS) technology. It is designed for applications requiring low power dissipation and high data rates. The DS90LV031A 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, disabling the load current, and thus dropping the device to a low idle power state. The EN and EN* inputs allow active Low or active High control of the TRI-STATE outputs. The enables are common to all four drivers. The DS90LV031A and companion line receiver (DS90LV032A) provide a new alternative to high power pseudo-ECL devices for high speed point-to-point interface applications. In addition, the DS90LV031A provides power-off high impedance LVDS outputs. This feature assures minimal loading effect on the LVDS bus lines when VCC is not present.
