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
