Overview: Product Folder Order Now Technical Documents Tools & Software Support & Community SN74CB3T3125 SCDS120C – FEBRUARY 2003 – REVISED DECEMBER 2018 SN74CB3T3125 Quadruple FET Bus Switch 2.5-V, 3.

General Description

The SN74CB3T3125 is a high-speed TTL-compatible FET bus switch with low ON-state resistance (ron), allowing for minimal propagation delay.

The device fully supports mixed-mode signal operation on all data I/O ports by providing voltage translation that tracks VCC.

The SN74CB3T3125 supports systems using 5-V TTL, 3.3-V LVTTL, and 2.5-V CMOS switching standards, as well as user-defined switching levels (see Typical DC Voltage-Translation Characteristics).

Key Features

  • 1 Output Voltage Translation Tracks VCC.
  • Supports Mixed-Mode Signal Operation On All Data I/O Ports.
  • 5-V Input Down to 3.3-V Output-Level Shift With 3.3-V VCC.
  • 5-V/3.3-V Input Down to 2.5-V Output-Level Shift With 2.5-V VCC.
  • 5-V-Tolerant I/Os With Device Powered Up or Powered Down.
  • Bidirectional Data Flow, With Near-Zero Propagation Delay.
  • Low ON-State Resistance (ron) Characteristics (ron = 5 Ω Typical).
  • Low Input/Output Ca.
