DESCRIPTION

The CBT6810 provides ten bits of high-speed TTL-compatible bus

switching. The low on-state resistance of the switch allows

bi-directional connections to be made while adding near-zero

propagation delay. The device also precharges the B port to a

user-selectable bias voltage (BIASV) to minimize live-insertion

noise.

The CBT6810 is organized as one 10-bit switch with a single enable

(OE) input. When OE is low, the switch is on and port A is

connected to port B. When OE is high, the switch between port A

and port B is open and the B port is precharged to BIASV through

the equivalent of a 10-k

Ω resistor.

The CBT6810 is characterized for operation from -40 to +85

°C.
