20-BIT BUS EXCHANGE SWITCH
NOTES:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 5.0V, +25°C ambient.
3. Per TTL driven input (VIN = 3.4V). All other inputs at VCC or GND.
4. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations.
5. IC = IQUIESCENT + IINPUTS + IDYNAMIC
IC = ICC +
ICC DHNT + ICCD (fiN)
ICC = Quiescent Current
ICC = Power Supply Current for a TTL High Input (VIN = 3.4V)
DH = Duty Cycle for TTL Inputs High
NT = Number of TTL Inputs at DH
ICCD = Dynamic Current Caused by an Input Transition Pair (HLH or LHL)
fi = Control Input Frequency
N = Number of Control Inputs Toggling at fi
All currents are in milliamps and all frequencies are in megahertz.

NOTES:
1. See test circuit and waveforms.
2. Minimum limits guaranteed but not tested.
3. This parameter is guaranteed by design but not tested.
4. 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 2.5ns for 50pF load. Since this time is constant and much smaller than the rise/fall times of typical driving signals,
it adds very little propagation delay to the system. Propagation delay on the bus switch when used in a system is determined by the driving circuit on
the driving side of the switch and its interaction with the load on the driven side.
5. Measured at switch turn off, load = 50 pF in parallel with 10 M
scope probe, VIN = 0.0 volts.
6. Measured at switch turn off through bus multiplexer, (e.g.- A to C = >A to D), load = 50 pF in parallel with 10 M
scope probe, VIN at A = 0.0 volts. Charge
injection is reduced because the injection from the turn off of the A to C switch is compensated by the turn on of the B to C switch.
7. Characterized parameter. Not 100% tested.
