INTRODUCTION
The UT54LVDS031 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 155.5 Mbps
(77.7 MHz) utilizing Low Voltage Differential Signaling
(LVDS) technology.
The UT54LVDS031 accepts 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 UT54LVDS031 and companion quad line receiver
UT54LVDS032 provide new alternatives to high power
pseudo-ECL devices for high speed point-to-point interface
applications.
