Product Introduction
The SN74CB3Q3257 device is a high-bandwidth FET bus switch utilizing a charge pump to elevate the gate voltage of the pass transistor, providing a low and flat ON-state resistance (rₒₙ).
Features
- High-Bandwidth Data Path (up to 500 MHz)
- 5-V Tolerant I/Os With Device Powered Up or Powered Down
- Low and Flat ON-State Resistance (rₒₙ) Characteristics Over Operating Range (rₒₙ = 4 Ω Typical)
- Rail-to-Rail Switching 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 and Output Capacitance Minimizes Loading and Signal Distortion (Cᵢₒ(OFF) = 3.5 pF Typical)
- Fast Switching Frequency (OE (overline) frequency f = 20 MHz Maximum)
- Data and Control Inputs Provide Undershoot Clamp Diodes
- Low Power Consumption (I₍₍CC₎₎ = 0.7 mA Typical)
- VCC Operating Range From 2.3 V to 3.6 V
- Data I/Os Support 0- to 5-V Signaling Levels (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, 5 V)
- Control Inputs Can Be Driven by TTL or 5-V/3.3-V CMOS Outputs
- Supports Partial-Power-Down Mode Operation
- Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II
- ESD Performance Tested Per JESD 22
- 2000-V Human Body Model (A114-B, Class II)
- 1000-V Charged-Device Model (C101)
- Supports Both Digital and Analog Applications: USB Interface, Differential Signal Interface, Bus Isolation, Low-Distortion Signal Gating
Applications
