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.
