5-V, 1:1 (SPST), 20-channel general-purpose FET bus switch with 2 control inputs

The SN74CBT16861 provides 20 bits of high-speed TTL-compatible bus switching. The low on-state resistance of the switch allows connections to be made with minimal propagation delay.

The device is organized as one dual 10-bit switch with separate output-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 is open, and the high-impedance state exists between the two ports.
