DESCRIPTION:
•
•
•
•
•
•
The CBTLV3862 provides ten bits of high-speed bus switching with low
on-state resistance of the switch allowing connections to be made with
minimal propagation delay.
The device is organized as one 10-bit bus switch. The switches are
controlled by independent active-low enable (OE) and active-high enable
(OE) controls.
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, and
OE should be tied to GND.

NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.

NOTES:
1. Typical Values are at VCC = 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.

(zero output impededance).
