SN74CB3Q16211 - 2.5-V/3.3-V Low-Voltage FET Bus Switch

Description

The SN74CB3Q16211 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).

Features

  • Member of the Texas Instruments Widebus® family.
  • 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 = 5 Ω typical).
  • Rail-to-rail switching on data I/O ports.
  • 0-V to 5-V switching with 3.3-V VCC.
  • 0-V to 3.3-V switching with 2.5-V VCC.
  • Bidirectional data flow, with near-zero propagation delay.
