Product Overview
The SN74CBT3306D from Texas Instruments is a high-speed 2-bit bus switch designed for digital signal routing and isolation. It features low on-state resistance (5 Ω typical) and wide bandwidth (250 MHz), making it suitable for high-frequency applications. The device operates from a 5V supply and is housed in an 8-pin SOIC package. It provides bidirectional switching with minimal propagation delay, ideal for bus isolation, voltage translation, and signal gating.
