The SY100EPT22V is a dual TTL/CMOS to differential
PECL translator. Capable of running from a 3.3 or 5V
supply, the part can be used in either LVTTL/LVCMOS/
LVPECL or TTL/CMOS/PECL systems.
The device only requires a single positive supply of
3.3V or 5V - no negative supply is required.
The tiny 8-pin MSOP package and the low skew, dual
gate design of the EPT22V makes it ideal for those
applications where space, performance, and low power
are at a premium.

Permanent device damage may occur if ABSOLUTE MAXIMUM
RATINGS are exceeded. This is a stress rating only and
functional operation is not implied at conditions other than those
detailed in the operational sections of this data sheet. Exposure
to ABSOLUTE MAXIMUM RATlNG conditions for extended
