Product specification
CBT6810
10-bit bus switch with precharged outputs
and Schottky undershoot protection for live insertion
2
1999 Apr 05
853–2151 21177
FEATURES
5Ω switch connection between port A and port B
TTL compatible input and output levels
Undershoot protection included to prevent shoot through level
changes
Bias voltage pre-charges the outputs to minimize signal distortion
during live insertion
DESCRIPTION
The CBT6810 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 CBT6810 is organized as one 10-bit switch with a single enable
(OE) input. When OE is low, the switch is on and port A is
connected to port B. When OE 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
Ω resistor.
The CBT6810 is characterized for operation from 0
°C to 85°C.
