Overview
The SN74CBTD3861PWR is a 10-bit FET bus switch manufactured by Texas Instruments. This component is designed for high-speed TTL-compatible bus switching and is particularly useful in level-shifting applications. It 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, and when it is high, the switch is open, resulting in a high-impedance state between the ports. The device is packaged in a 24-pin TSSOP (Thin Shrink Small Outline Package) and operates over a temperature range of -40°C to 85°C.
