DESCRIPTION
The SY89329V is a TTL/CMOS-to-differential PECL
translator. Capable of running from a 3.3V or 5V supply,
the part can be used in either LVTTL/LVCMOS/LVPECL or
TTL/CMOS/PECL systems.
The device requires only a single positive supply of 3.3V
or 5V; no negative supply is required.
The ultra-small 8-pin MLF™ package of the SY89329V
makes it ideal for applications where space, performance,
and low power are at a premium. For applications that require
a dual translator in this same ultra-small MLF™ package,
consider the SY89322V.
All support documentation can be found on Micrel’s web
