Motorola, Inc. 1996

The MC10E457/100E457 is a 3-bit differential 2:1 multiplexer . The fully
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 higher frequency outputs provide the device with a >1.0GHz
bandwidth to meet the needs of the most demanding system clock.
Both, separate selects and a common select, are provided to make the
device well suited for both data path and random logic applications.
The differential inputs have internal clamp structures which will force
the Q output of a gate in an open input condition to go to a LOW state.
Thus, inputs of unused gates can be left open and will not affect the
operation of the rest of the device. Note that the input clamp will take
affect only if both inputs fall 2.5V below VCC.

is defined as the range within which the VIH level may vary, with the device still meeting the propagation delay specification. The VIL level
must be such that the peak to peak voltage is less than 1.0 V and greater than or equal to VPP(min).

1. Within-device skew is defined as identical transitions on similar paths through a device.
2. 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.
3. Minimum input swing for which AC parameters are guaranteed.
