SN74LXC1T45DCKR is a 1-bit, DIR-controlled bidirectional level translator for push-pull logic signals between independently supplied 1.1 V to 5.5 V domains.

Best for

  • Single-bit push-pull logic translation
  • Mixed-voltage GPIO and reset/status signals
  • Applications requiring partial-power-down isolation

Avoid if

  • Automatic direction sensing is required
  • Both sides may actively drive simultaneously
  • Open-drain translation is required without external circuit design

Check before use

  • VCCA and VCCB operating voltages
  • DIR timing and ownership during bus reversal
  • Output current and capacitive load
  • SC70-6 assembly capability
