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 MLFTM 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 MLFTM package,
consider the SY89322V.
All support documentation can be found on Micrel's web
site at www.micrel.com.

Notes:
1. Permanent device damage may occur if the "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 the absolute maximum ratings conditions
for extended periods may affect device reliability.
2. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.
3. Package Thermal Resistance assumes exposed pad is soldered (or equivalent) to the devices most negative potential on the PCB.
JB
uses 4-layer
JA
in still-air unless otherwise stated.
4. The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established.
