2.5 V/3.3 V ECL DUAL
Differential 2:1 Multiplexer
NB100LVEP56
Description
The NB100LVEP56 is a dual, fully differential 2:1 multiplexer. The
differential data path makes the device ideal for multiplexing low
skew clock or differential data signals. The device features both
individual and common select inputs to address both data path and
random logic applications. Common and individual selects can accept
both LVECL and LVCMOS input voltage levels. Multiple VBB pins
are provided.
The VBB pin, an internally generated voltage supply, is available to
this device only. For single−ended input operation, the unused
differential input is connected to VBB as a switching reference voltage.
VBB may also rebias AC coupled inputs. When used, decouple VBB
and VCC via a 0.01 mF capacitor and limit current sourcing or sinking
to 0.5 mA. When not used, VBB should be left open.
