SN74CB3Q3253 - 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).

Features

  • 1 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.
