MC100EPT21
Differential LVPECL to
LVTTL Translator
The MC100EPT21 is a 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 makes
the EPT21 ideal for applications which require the translation of a
clock or data signal.
The VBB output allows the EPT21 to also be used in a single–ended
input mode. In this mode the VBB output is tied to the D0 input for a
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.
