HIGH-SPEED CMOS QUICKSWITCH 16:8 MULTIPLEXER
NOTES:
1. For conditions shown as Mn. or Max., use the appropriate values specified under DC Electrical Characteristics.
2. Per TTL-driven input (V
IN
= 3.4V, control inputs only). A, B, and AB pins do not contribute to
Icc.
3. This current applies to the control inputs only and represents the current required to switch internal capacitance at the specified frequency. The A, B, and AB inputs generate
no significant AC or DC currents as they transition. This parameter is guaranteed but not production tested.

NOTES:
1. Mnimums are guaranteed but not production tested.
2. This parameter is guaranteed but not production tested.
3. The bus switch contributes no propagation delay other than the RC delay of the ON resistance of the switch and the load capacitance. The time constant for the switch alone
is of the order of 0.25ns at C
L
= 50pF. Since this time constant is much smaller than the rise and fall times of typical driving signals, it adds very little propagation delay to the
system Propagation delay of the bus switch, when used in a system is determned by the driving circuit on the driving side of the switch and its interaction with the load on
the driven side.
