Dual 1-of-4 FET Multiplexer/Demultiplexer 2.5-V/3.3-V Low-Voltage High-Bandwidth Bus Switch

 

Description

The SN74CB3Q3253 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 rail-to-rail switching on the data input and output (I/O) ports.

Features

  • High-Bandwidth Data Path (Up to 500 MHz) (1)
  • 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/Output Capacitance Minimizes Loading and Signal Distortion (Cio(OFF) = 3.5 pF Typical)
  • Fast Switching Frequency (fOE = 20 MHz Max)
  • Data and Control Inputs Provide Undershoot Clamp Diodes
  • Low Power Consumption (ICC = 0.6 mA Typical)
  • VCC Operating Range From 2.3 V to 3.6 V
  • Data I/Os Support 0- to 5-V Signal 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 and 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)
