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 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.

NOTES:
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.
4. The CMR 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 V
PP
(min) and 1V. The lower end of the CMR range varies 1:1 with V
EE
. The numbers in the spec table
assume a nominal V
EE
= –3.3V. Note for PECL operation, the V
CMR
(min) will be fixed at 3.3V – |V
CMR
(min)|.
5. The CMR range is referenced to the most positive side of the differential
input signal. Normal operation is obtained if the HIGH level falls within the
PRODUCT ORDERING CODE
specified range and the peak-to-peak voltage lies between V
PP
(min) and
1V. The lower end of the CMR range varies 1:1 with V
EE
. The numbers
in the spec table assume a nominal V
EE
= –4.5V. Note for PECL operation,
