IDT74CBTLV3861
LOW-VOLTAGE 10-BIT
BUS SWITCH
DESCRIPTION:
The CBTLV3861 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. When output enable
(OE) is low, the 10-bit bus switch is on and port A is connected to port B.
When OE is high, the switch is open and a high-impedance state exists
between the two ports.
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.

NOTE:
1. The propagation delay is the calculated RC time constant of the typical on-state resistance of the switch and the specified load capacitance driven by an ideal voltage source
(zero output impedance).
SWITCHING CHARACTERISTICS
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.
