Overview
The SN74CBTD3861DW is a 10-bit FET bus switch with level shifting, manufactured by Texas Instruments. This component is designed to provide high-speed TTL-compatible bus switching, making it suitable for applications requiring minimal propagation delay and level shifting between different voltage levels.
The device features a single output-enable (OE) input that controls the connection between two ports. When the OE input is low, the switch is on, connecting port A to port B. When the OE input is high, the switch is open, resulting in a high-impedance state between the two ports.
The SN74CBTD3861DW is packaged in a 24-pin SOIC (DW) package and operates over a temperature range of -40°C to 85°C.
