MC100EPT26
1:2 Fanout Differ ential
LVPECL to LVTTL
Translator
The MC100EPT26 is a 1:2 Fanout Differential LVPECL to L VTTL
translator. Because LVPECL (Positive ECL) levels are used only
+3.3V and ground are required. The small outline 8–lead SOIC
package and the 1:2 fanout design of the EPT26 makes it ideal for
applications which require the low skew duplication of a signal in a
tightly packed PC board.
The VBB output allows the EPT26 to be used in a single–ended
input mode. In this mode the VBB output is tied to the D0
non–inverting buffer or the D0 input for an inverting buffer. If used,
the VBB pin should be bypassed to ground via a 0.01µF capacitator.
