MC100EPT23
Dual Differential LVPECL to
LVTTL Translator
The MC100EPT23 is a dual differential LVPECL to LVTTL
translator. Because LVPECL (Positive ECL) levels are used only
+3.3V and ground are required. The small outline 8-lead SOIC
package and the dual gate design of the EPT23 makes it ideal for
applications which require the translation of a clock and a data signal.
The EPT23 is available in only the ECL 100K standard. Since there
are no L VPECL outputs or an external VBB reference, the EPT23 does
not require both ECL standard versions. The LVPECL inputs are
differential. Therefore, the MC100EPT23 can accept any standard
differential LVPECL input referenced from a VCC of +3.3V.
