TERMINOLOGY
Positive Power Supply Voltage.
Ground (0 V) Reference.
Minimum Input Voltage for Logic 1.
Maximum Input Voltage for Logic 0.
Input Leakage Current at the Control Inputs.
OFF State Leakage Current. It is the maximum leakage current at the switch pin in the OFF state.
ON State Leakage Current. It is the maximum leakage current at the switch pin in the ON state.
Maximum Pass Voltage. The maximum pass voltage relates to the clamped output voltage of an NMOS device when
the switch input voltage is equal to the supply voltage.
Ohmic Resistance Offered by a Switch in the ON State. It is measured at a given voltage by forcing a specified
amount of current through the switch.
On Resistance Match between Any Two Channels, i.e., RON Max – RON Min.
OFF Switch Capacitance.
ON Switch Capacitance.
Control Input Capacitance. This consists of BEx and SEL.
Quiescent Power Supply Current. It is measured when all control inputs are at a logic HIGH or LOW level and
the switches are OFF.
Extra power supply current component per each BEx control input when the Input is not driven at the supplies.
Data Propagation Delay through the Switch in the ON State. Propagation delay is related to the RC time constant
RON Ï« CL, where CL is the load capacitance.
Bus Enable Times. These are the times taken to cross the VT voltage at the switch output when the switch turns on
in response to the control signal, BEx.
Bus Disable Times. These are the times taken to place the switch in the high impedance OFF state in response to the
control signal. They are measured as the time taken for the output voltage to change by V⌬ from the original quiescent
level, with reference to the logic level transition at the control input. (Refer to Figure 3 for enable and disable times.)
Maximum Rate at which Data Can Be Passed through the Switch.
Peak-to-Peak Value of the Sum of the Deterministic and Random Jitter of the Switch Channel.
Operating Frequency of Bus Enable. This is the maximum frequency at which bus enable (BEx) can be toggled.
