SN74CB3Q3345 - 2.5-V/3.3-V LOW-VOLTAGE HIGH-BANDWIDTH BUS SWITCH

Datasheet Summary

Description

The SN74CB3Q3345 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)).
  • 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/Output Capacitance Minimizes Loading and Signa.
