The SN74CBTLV16210 provides 20 bits of high-speed bus switching. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The device is organized as dual 10-bit bus switches with separate output-enable (OE) inputs. It can be used as two 10-bit bus switches or one 20-bit bus switch. When OE is low, the associated 10-bit bus switch is on and port A is connected to port B. When OE is high, the switch is open, and the high-impedance state exists between the two ports.
