DESCRIPTION
The CBT6820 provides twenty 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.
   
FEATURES
• TTL compatible inputs and outputs
• 5Ω switch connection between two port A and port B
• Thin shrink small outline (TSSOP)
• Undershoot protection included to prevent shoot through level
    changes
• Bias voltage pre-charges the outputs to minimize signal distortion
