The TC7SB385FU provides single bit of high-speed TTL-compatible switching. The low on resistance of the switch allows connections to be made with minimal propagation delay. The device is organized as just 1-bit low-impedance switch with output-enable (OE) input. When OE is high, the switch is on and data can flow from port A to port B, or vice versa. When OE is low, the switch is open and a high-impedance state exists between the two ports.
