INTRODUCTION
The UT54LVDS032 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 155.5 Mbps
(77.7 MHz) utilizing Low Voltage Differential Signaling
(LVDS) technology.
The UT54LVDS032 accepts low voltage (340mV)
differential input signals and translates them to 5V TTL
output levels. The receiver supports a three-state function
that may be used to multiplex outputs. The receiver also
supports OPEN, shorted and terminated (100 ) input fail-
safe. Receiver output will be HIGH for all fail-safe
conditions.
The UT54LVDS032 and companion quad line driver
UT54LVDS031 provides new alternatives to high power
pseudo-ECL devices for high speed point-to-point interface
applications.

... Receiver Fail-Safe The UT54LVDS032 receiver is a high gain, high speed device that amplifies a small differential signal (20mV) to TTL logic levels. Due to the high gain and tight threshold of the receiver, care should be taken to prevent noise from appearing as a valid signal. The receiver’s internal fail-safe circuitry is designed to source/ ...
