LOW-VOLTAGE 10-BIT
BUS SWITCH WITH
PRECHARGED OUTPUTS
DESCRIPTION:
The CBTLV6800 provides 10-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 also precharges the B port to a
user-selectable bias voltage (BIASV) to minimize live-insertion noise.
The CBTLV6800 is organized as a single 10-bit bus switch with a single
output-enable (OE) input. When 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, and port B is precharged
to BIASV through the equivalent of a 10-kΩ resistor.
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. The increase in supply current is attributable to each current that is at the specified voltage level rather than VCC or GND.
2. This is measured by the voltage drop between the A and B terminals at the indicated current through the switch. On-state resistance is determined by the lower of the voltages
of the two (A or B ) terminals.
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).
