The PI3B16215 provides 20-bits of high-speed bus switching. Low on-state resistance of the switch allows connections to be made with minimal propagation delay. The device also precharges the B-port to a user-selectable bias voltage (BIASV) to minimize liveinsertion noise. The device is organized as dual 10-bit bus switches with individual output-enable (OE) inputs. When OE is LOW, the corresponding 10-bit bus switch is on and port A is connected to port B. When OE is HIGH, the switch is open, a high-impedance state exists between the two...
