Texas Instruments  SN74CBT3345PWR

The SN74CBT3345 provides eight bits of high-speed TTL-compatible bus switching in a standard ’245 device pinout. The low on-state resistance of the switch allows connections to be made with minimal propagation delay.

The device is organized as one 8-bit switch bank with dual output-enable (OE and OE)\ inputs. When OE\ is low or OE is high, the switch is on, and port A is connected to port B. When OE\ is high and OE is low, the switch is open, and the high-impedance state exists between the two ports.
