description
The SN74CBTS6800 provides ten bits of
high-speed TTL-compatible bus switching with
Schottky diodes on the I/Os to clamp
undershoots.
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 SN74CBTS6800 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-kW resistor.
