74CB3Q3306ADCURG4

74CB3Q3306ADCURG4 from Texas Instruments is a Integrated Circuit 3.3-V, 1:1 (SPST), 2-channel FET bus switch (active low) - Protocol & bus switches & muxes. The SN74CB3Q3306A 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 rail-to-rail switching 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 SN74CB3Q3306A device provides an optimized interface option appropriate for broadband communications, networking, and data-intensive computing systems. The SN74CB3Q3306A device is organized as two 1-bit switches with separate output-enable (1 OE, 2 OE) inputs. It can be used as two 1-bit bus switches or as one 2-bit bus switch. When OE is low, the associated 1-bit bus switch is ON and the A port is connected to the B port, allowing bidirectional data flow between ports. When OE is high, the associated 1-bit bus switch is OFF, and a high-impedance state exists between the A and B ports. The SN74CB3Q3306A 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 confirm the high-impedance state during power up or power down, OE must be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
