TERMINOLOGY

Positive Power Supply Voltage

GND

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.

Max Pass Voltage. The max 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.

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

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.)

Max Data Rate

Maximum Rate at which Data Can Be Passed through the Switch

Channel Jitter

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 (BE) can be toggled.
