Product Overview
The SN74CBT3306CPWR 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 applications requiring minimal signal distortion. The device operates over a wide supply voltage range of 4.5 V to 5.5 V and is available in a compact 8-TSSOP package. It supports bidirectional data flow with near-zero propagation delay, ideal for bus isolation and voltage translation.
