ON MC100EL56 5v ecl dual differential 2:1 multiplexer Datasheet

MC100EL56
5VECL 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 VBB pins are
provided to ease AC coupling input signals.
The VBB pins, an internally generated voltage supply, are available
to this device only. For single-ended input conditions, 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.
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 VEE. The D input will bias
around VCC/2 forcing the Q output LOW.

NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the declared
operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit
values are applied individually under normal operating conditions and not valid simultaneously.
2. Input and output parameters vary 1:1 with VCC. VEE can vary +0.8 V / −0.5 V.
3. Outputs are terminated through a 50 W resistor to VCC − 2.0 V.
4. VIHCMR min varies 1:1 with VEE, VIHCMR max varies 1:1 with VCC. The VIHCMR range is referenced to the most positive side of the differential
input signal. Normal operation is obtained if the HIGH level falls within the specified range and the peak-to-peak voltage lies between VPPmin
and 1 V.

8. VEE can vary +0.8 V / −0.5 V.
9. Within-device skew is defined as identical transitions on similar paths through a device.
10. Duty cycle skew is defined only for differential operation when the delays are measured from the cross point of the inputs to the cross point
of the outputs.
11. VPP(min) is minimum input swing for which AC parameters guaranteed. The device has a DC gain of ≈ 40.
