DESCRIPTION
The SY89223L is a 3.3V, precision dual differential LVPECL-to-LVTTL translator. The ultra-small 8-pin MLF package and the low skew, dual gate design of this translator makes it ideal for applications which require the translation of a clock and a data signal. The SY89223L translator accepts 10k or 100k differential LVPECL inputs.

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 periods may affect device reliability. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings. Package thermal resistance assumes exposed pad is soldered (or equivalent) to the device's most negative potential on the PCB. VIHCMR(min) varies 1:1 with VEE, Max varies 1:1 with VCC.
