Preliminary
DUAL FET BUS SWITCH 2.5V OR 3.3V LOW-VOLTAGE HIGH-BANDWIDTH BUS SWITCH
CMOS IC
DESCRIPTION
The U74CB3Q3305 device is a high-bandwidth FET bus switch using a charge pump to elevate the gate voltage of the pass transistor, providing a low and flat ON-state resistance (RON). The low and flat ON-state resistance allows for minimal propagation delay and supports switching input voltage beyond the supply on the data input/output (I/O) ports. The device also features low data I/O capacitance to minimize capacitive loading and signal distortion on the data bus.
