FIN1002
LVDS 1-Bit High Speed Differential Receiver
General Description
This single receiver is designed for high speed intercon-
nects utilizing Low Voltage Differential Signaling (LVDS)
technology. The receiver translates LVDS levels, with a typ-
ical differential input threshold of 100 mV, to LVTTL signal
levels. LVDS provides low EMI at ultra low power dissipa-
tion even at high frequencies. This device is ideal for high
speed transfer of clock or data.
The FIN1002 can be paired with its companion driver, the
FIN1001, or with any other LVDS driver.

Note 1:
The “Absolute Maximum Ratings”: are those values beyond which
damage to the device may occur. The databook specifications should be
met, without exception, to ensure that the system design is reliable over its
power supply, temperature and output/input loading variables. Fairchild
does not recommend operation of circuits outside databook specification.
