74CB3Q3257BQ
Overview
The 74CB3Q3257 is a quad high-bandwidth single-pole, double-throw FET bus switch. The device features one select input (S) and one output enable input (OE).
- Wide supply voltage range from 2.3 V to 3.6 V
- Overvoltage switching on switch ports: - 0 V to 5 V switching with VCC = 2.5 V - 0 V to 5 V switching with VCC = 3.3 V
- 4 Ω (typical) ON resistance
- 3.5 pF (typical) OFF-state capacitance
- High bandwidth 0.5 GHz (maximum)
- Low input/output capacitance minimizes loading and signal distortion
- Fast switching frequency fmax = 20 MHz (maximum)
- Low power consumption ICC = 0.4 mA (typical)
- Control inputs can be driven by TTL or 5 V/3.3 V CMOS outputs
- IOFF supports partial power-down mode operation
