Information

The SN74CB3Q3306 is a high-bandwidth FET bus switch utilizing a charge pump to elevate the gate voltage ofthe pass transistor, providing a low and flat ON-state resistance (ron). The low and flat ON-state resistance allowsfor minimal propagation delay and supports rail-to-rail switching on the data input/output (I/O) ports. The devicealso 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 provides an optimizedinterface solution ideally suited for broadband communications, networking, and data-intensive computingsystems.

Key Features

  • High-Bandwidth Data Path (up to 500 MHz(1)) Clamp Diodes
  • Low Power Consumption (ICC = 0.25 mA Typ)
  • 5-V-Tolerant I/Os With Device Powered Up or Powered Down
  • VCC Operating Range From 2.3 V to 3.6 V
  • Low and Flat ON-State Resistance (ron)
  • Data I/Os Support 0- to 5-V Signaling Levels Characteristics Over Operating Range (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, 5 V) (ron = 4 Ω Typ)
  • Control Inputs Can Be Driven by TTL or
  • Rail-to-Rail Switching on Data I/O Ports 5-V/3.3-V CMOS Outputs
    • 0- to 5-V Switching With 3.3-V VCC
  • Ioff Supports Partial-Power-Down Mode
    • 0- to 3.3-V Switching With 2.5-V V Operation CC
  • Bidirectional Data Flow With Near-Zero
  • Latch-Up Performance Exceeds 100 mA Propagation Delay Per JESD 78, Class II
  • Low Input/Output Capacitance Minimizes
  • ESD Performance Tested Per JESD 22 Loading and Signal Distortion – 2000-V Human-Body Model (Cio(OFF) = 3.5 pF Typ) (A114-B, Class II)
  • Fast Switching Frequency (f OE = 20 MHz Max)
