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 input for an inverting buffer. If used, the VBB pin should be bypassed to ground via a 0.01mF capacitator.
