DESCRIPTION
The CBT6800 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 CBT6800 is organized as one 10-bit switch with a single enable
(ON) input. When ON is low, the switch is on and port A is
connected to port B. When ON 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 resistor.
The CBT6800 is characterized for operation from –40 C to 85 C.
