U74CB3Q3305 Datasheet | Unisonic Technologies

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. Specifically designed to support high-bandwidth applications, the U74CB3Q3305 device provides an optimized interface solution ideally suited for broadband munications, networking, and data-intensive puting systems. This device is fully specified for partial-power-down applications using IOFF. The IOFF circuitry prevents damaging current backflow through the device when it is powered down. The device has isolation during power off To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pull down resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver. - FEATURES - Operation Voltage Range: 2.3 ~ 3.6V - Low power consumption, 0.25m A Typ.
