Translators

1-bitbidirectionaldual-supplylevel translatorbus hold0.65 V to 3.6 VSON-6

SN74AXCH1T45DRY2 is a 1-bit bidirectional dual-supply level translator for 0.65 V to 3.6 V logic domains. It uses DIR for direction selection and includes bus-hold inputs and partial-power-down protection.

Best for

  • Bidirectional single-bit level translation
  • Low-voltage logic interfaces
  • UART or IRQ signal translation

Avoid if

  • An automatic-direction level shifter is required
  • The bus requires an independent output-enable control
  • External pull resistors are mandatory on the translated data node

Check before use

  • VCCA and VCCB voltage ranges
  • DIR timing during bus turnaround
  • Output load capacitance and required data rate
  • Bus-hold interaction with connected circuitry
