MC100EL56/D
MC100EL56
5V ECL Dual Differential
2:1 Multiplexer
Description
The MC100EL56 is a dual, fully differential 2:1 multiplexer. The
differential data path makes the device ideal for multiplexing low
skew clock or other skew sensitive signals. Multiple V
BB
pins are
provided to ease AC coupling input signals.
The V
BB
pins, an internally generated voltage supply, are available
to this device only. For single-ended input conditions, the unused
differential input is connected to V
BB
as a switching reference voltage.
V
BB
may also rebias AC coupled inputs. When used, decouple V
BB
and V
CC
via a 0.01 mF capacitor and limit current sourcing or sinking
to 0.5 mA. When not used, V
BB
should be left open.
The device features both individual and common select inputs to
address both data path and random logic applications.
The differential inputs have special circuitry which ensures device
stability under open input conditions. When both differential inputs
are left open, the D input will pull down to V
EE
. The D input will bias
around V
CC
/2 forcing the Q output LOW.
