SN74CB3Q3305 Description
The SN74CB3Q3305 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.
SN74CB3Q3305 Key Features
- High-bandwidth data path (up to 500 MHz)1
- 5-V tolerant I/Os with device powered up or
- Low and flat ON-state resistance (ron)
- Supports input voltage beyond supply on data I/O ports
- 0 to 5 V switching with 3.3 V VCC
- 0 to 3.3 V switching with 2.5 V VCC
- Bidirectional data flow with near-zero propagation delay
- Low input or output capacitance minimizes loading and signal distortion (Cio(OFF) = 3.5 pF typical)
- Fast switching frequency (fOE = 20 MHz maximum)
- Data and control inputs provide undershoot clamp diodes
