The SN74CBTD3861 provides ten 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. A diode to VCC is integrated on the die to allow for level shifting from 5-V signals at the device inputs to 3.3-V signals at the device outputs.
The device is organized as one 10-bit switch with a single 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.
