ANALOG PART SPECIFICATIONS

NOTE 1: all the parameters are valid only with a 75

Ω (±5%) load to GND.

NOTE 2: measured with a 5V DC voltage applied to a closed switch.

NOTE 3: not tested in production.

NOTE 4: measured with a 2Vpp signal.

NOTE 5: measured with the line connected to GND at one side with a 75

Ω resistor and all the other lines driven by a 1MHz, 2Vpp sine wave

signal.

NOTE 6: during the switching between the main and spare ports, the behaviour of the component is not guaranteed: both main switches can

be open (break before make).

NOTE 7: measured with the line switching from a 2.5V DC level (main or spare port) to a -2.5V DC level (spare or main port).

CURRENT CONSUMPTION SPECIFICATIONS

NOTE 1: these parameters are not tested in production.

NOTE 2: this power is not delivered by VPOS and VNEG supplies but by the signal sources.

NOTE 3: only valid with digital inputs to GND or VPOS levels.
