The UT54LVDS031LV Quad Driver 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 400.0 Mbps (200 MHz) utilizing Low Voltage Differential Signaling (LVDS) technology. The UT54LVDS031LV accepts low voltage TTL input levels and translates them to low voltage (340mV) differential output signals. In addition, the driver supports a three-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. The UT54LVDS031LV and companion quad line receiver UT54LVDS032LV provide new alternatives to high power pseudo-ECL devices for high speed point-to-point interface applications. All pins have Cold Spare buffers. These buffers will be high impedance when VDD is tied to VSS.
