FIN1027 FIN1027A
3.3V LVDS 2-Bit High Speed Differential Driver
General Description
This dual driver is designed for high speed interconnects
utilizing Low Voltage Differential Signaling (LVDS) technol-
ogy. The driver translates LVTTL signal levels to LVDS lev-
els with a typical differential output swing of 350 mV which
provides low EMI at ultra low power dissipation even at
high frequencies. This device is ideal for high speed trans-
fer of clock or data.
The FIN1027 or FIN1027A can be paired with its compan-
ion receiver, the FIN1028, or with any other LVDS receiver.

Absolute Maximum Ratings
(Note 1)
Recommended Operating
Conditions
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.
