description
The SN74CBTS6800 provides ten bits of
high-speed TTL-compatible bus switching with
Schottky diodes on the I/Os to clamp undershoot.
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 V
CC
is 0 V, B port is precharged to BIASV through the equivalent of a 10-k
resistor.
The SN74CBTS6800 is characterized for operation from –40
°
C to 85
°
C.
