Overview: Product Folder Order Now Technical Documents Tools & Software Support & Community SN74CB3Q3257 SCDS135D – SEPTEMBER 2003 – REVISED JULY 2018 SN74CB3Q3257 4-Bit 1-of-2 FET Multiplexer/Demultiplexer 2.5-V/3.

General Description

The SN74CB3Q3257 device is a high-bandwidth FET bus switch utilizing a charge pump to elevate the gate voltage of the pass transistor,

Key Features

  • 1 High-Bandwidth Data Path (up to 500 MHz).
  • 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 and Output Capacitance Minimizes Loading and S.
