Information

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).

Key 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 (f OE = 20 MHz
    Maximum)
  • Data and Control Inputs Provide Undershoot
    Clamp Diodes
  • Low Power Consumption
    (ICC = 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
  • Ioff 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(1)
  • Technical Attributes
