SN74CB3T1G125 Datasheet 2.5-v/3.3-v Low-voltage Switch

Manufacturer: Texas Instruments

Overview: www.ti.com SN74CB3T1G125 SINGLE FET BUS SWITCH 2.5-V/3.3-V LOW-VOLTAGE SWITCH WITH 5-V-TOLERANT LEVEL SHIFTER SCDS150A – OCTOBER 2003 – REVISED SEPTEMBER.

General Description

/ORDERING INFORMATION The SN74CB3T1G125 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 SN74CB3T1G125 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 Figure 1).

Key Features

  • 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 Typ).
  • Low Input/Output Capaci.
