Texas Instruments  SN74CBTD3384DWR

The ’CBTD3384 devices provide ten bits of high-speed TTL-compatible bus switching. The low on-state resistance of the switches allows connections to be made without adding propagation delay. A diode to VCC is integrated on the die to allow for level shifting between 5-V inputs and 3.3-V outputs.

These devices are organized as two 5-bit switches with separate output-enable (OE\) inputs. 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.
