SN74CB3Q3245 - 8-BIT FET BUS SWITCH

Description

The SN74CB3Q3245 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 (1)).
  • Equivalent to IDTQS3VH384 Device.
  • 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 Typ).
  • 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/Out.
