LOW-VOLTAGE 12-BIT 1:2 MUX / DEMUX BUS SWITCH
DC ELECTRICAL CHARACTERISTICS OVER OPERATING RANGE
Following Conditions Apply Unless Otherwise Specified:
Operating Condition: TA = –40°C to +85°C
NOTES:
1. Typical values are at 3.3V, +25°C ambient.
2. The increase in supply current is attributable to each input that is at the specified voltage level rather than VCC or GND.
3. This is measured by the voltage drop between the A and B terminals at the indicated current through the switch.

NOTES:
1. The propagation delay is the calculated RC time constant of the typical on-state resistance of the switch and the specified load capacitance when driven by an ideal voltage
source (zero output impedance).
2. The condition to measure this propagation delay is by observing the change of voltage on the A port introduced by static fields equal to 3V or 0V for 3.3V±0.3V or VCC or 0 for
2.5V±0.2V on B1 and B2 ports to get the required transition.
3. The make-before-break time is the duration between the make and break, during transition from one selected port to another.
4. This parameter is guaranteed by design but not production tested.
