description

The SN74CBT6800A provides ten bits of

high-speed TTL-compatible bus switching. The

low on-state resistance of the switch allows

bidirectional 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 SN74CBT6800A 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.

When ON is high or VCC is 0 V, B port is precharged to BIASV through the equivalent of a 10-kΩ resistor.
