DESCRIPTION
Resistance between source and drain with switch in the ON state.
Output leakage current measured at S1, S2, and D with the switch OFF.
Digital voltage at the IN pin that selects between S1 and S2 analog inputs.
Voltage applied to the D or S1, S2 pins when D or S1, S2 is the switch input.
A voltage that ENABLES the chip.
Capacitance at the digital inputs.
Capacitance at analog I/O (S1, S2, D) with switch OFF.
Capacitance at analog I/O (S1, S2, D) with switch ON.
Minimum input voltage for logic HIGH.
Minimum input voltage for logic LOW.
Input current of the digital input.
Propagation delay measured between 50% of the digital input to 90% of the analog output when
switch is turned ON.
Propagation delay measured between 50% of the digital input to 90% of the analog output when
switch is turned OFF.
Frequency response of the switch in the ON state measured at 3dB down.
Is an unwanted signal coupled from channel to channel. Measured in -dB. X_TALK = 20LOG V_OUT/V_IN.
This is non-adjacent crosstalk.
Magnitude variation between analog input and output pins when the switch is ON and the dc offset
of composite-video signal varies at the analog input pin. In the NTSC standard, the frequency of
the video signal is 3.58MHz.
Phase variation between analog input and output pins when the switch is ON and the dc offset of
composite-video signal varies at the analog input pin. In the NTSC standard, the frequency of the
video signal is 3.58MHz.
Off isolation is the resistance (measured in -dB) between the input and output with the switch off
(NO).
