BUS SWITCH
NOTE:
1. Pin numbers shown apply to the 14-pin TSSOP package.
DESCRIPTION:
The CBTLV3125 features four independent switches. Each switch is
enabled when the associated output-enable (OE) input is low.
To ensure the high-impedance state during power up or power down,
OE should be tied to VCC through a pullup resistor; the minimum value of
the resistor is determined by the current-sinking capability of the driver.

DC ELECTRICAL CHARACTERISTICS OVER OPERATING RANGE
Following Conditions Apply Unless Otherwise Specified:
Operating Conditions: TA = –40°C to +85°C
NOTES:
1. Typical values are at VCC = 3.3V, +25°C ambient.
2. The increase in supply current is attributable to each current 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.
VCC = 2.5V ± 0.2V VCC = 3.3V ± 0.3V
