MOTOROLA MC10EPT20D, MC10EPT20DR2 Datasheet
MC10EPT20
LVTTL/LVCMOS to
Differential LVPECL Translator
The MC10EPT20 is a LVTTL/LVCMOS to differential LVPECL
translator. Because LVPECL (Positive ECL) levels are used only
+3.3V and ground are required. The small outline 8–lead SOIC
package and the single gate of the EPT20 makes it ideal for those
applications where space, performance, and low power are at a
premium.
