description

The SN74CBT6800 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 SN74CBT6800 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-kΩ resistor.

The SN74CBT6800 is characterized for operation from -40°C to 85°C.
