MC100EPT25

Differential LVECL/ECL to
LVTTL Translator

The MC100EPT25 is a Differential LVECL/ECL to LVTTL
translator. This device requires +3.3V, –3.3V to –5.2V, and ground.
The small outline 8–lead SOIC package and the single gate of the
EPT25 make it ideal for applications which require the translation of a
clock or data signal.

The VBB output allows the EPT25 to also be used in a single–ended
input mode. In this mode the VBB output is tied to the D input for a
non–inverting buffer or the D
VBB pin should be bypassed to ground via a 0.01mF capacitator.
