POWER SUPPLY CHARACTERISTICS
NOTES:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type. TA = –40°C to +85°C
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. Switch inputs do not contribute to
ΔICC.
4. This parameter represents the current required to switch the internal capacitance of the control inputs at the specified frequency.
Switch inputs generate no significant power supply currents as they transition. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations.
5. CPD = ICCD/VCC
CPD = Power Dissipation Capacitance
6. IC = IQUIESCENT + IINPUTS + IDYNAMIC
IC = ICC +
ΔICC DHNT + ICCD (fiN)
ICC = Quiescent Current
ΔICC = 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
SWITCHING CHARACTERISTICS OVER OPERATING RANGE
Following Conditions Apply Unless Otherwise Specified:
Industrial: TA = -40°C to +85°C, VCC = 5.0V ± 10%
VCC = 5V ± 10%
VCC = 4V

NOTES:
1. See test circuits and waveforms.
2. The bus switch contributes no Propagation Delay other than the RC Delay of the load interacting with the RC of the switch.
3. |QCI| is the charge injection for a single switch DISCONNECT and applies to either single switches or multiplexers. |QDCI| is the charge injection for a multiplexer as
the multiplexed port switches from one path to another. Charge injection is reduced because the injection from the DISCONNECT of the first path is compensated by
the CONNECT of the second path.
