INTRODUCTION
The UT54LVDS032LV Quad Receiver is a quad CMOS
differential line receiver 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 UT54LVDS032LV accepts low voltage (340mV)
differential input signals and translates them to 5V TTL o utput
levels. The receiver supports a three-state function that may be
used to multiplex outputs. The receiver also supports OPEN,
shorted and terminated (100
鈩?
input fail-safe. Receiver output
will be HIGH for all fail-safe conditions.
The UT54LVDS032LV and companion quad line driver
UT54LVDS031LV provides 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 V
