SN74CBT16211CDGGR is a 56-pin, dual 12-bit FET bus switch for 5-V logic buses requiring low-resistance bidirectional connection and controlled isolation.

Best for

  • 5-V bidirectional bus isolation
  • PCI-interface signal switching
  • Memory interleaving and low-distortion signal gating

Avoid if

  • A voltage-level translation function is required
  • The design cannot accommodate a 56-pin 0.5 mm-pitch TSSOP
  • Control logic cannot guarantee a defined OE state during power transitions

Check before use

  • Verify connected buses do not exceed the specified data-I/O voltage range.
  • Tie OE to VCC through a pullup resistor when high-impedance isolation is required during power-up or power-down.
  • Evaluate voltage drop and RC loading at the expected signal current and capacitance.
