SN74LS245DW Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the SN74LS245DW is 30 MHz.
  • Yes, the SN74LS245DW is compatible with 3.3V systems, but the output voltage will be limited to 3.3V. However, the input voltage can be up to 5V.
  • When not in use, the enable inputs (G1 and G2) should be tied to VCC or GND to prevent floating inputs, which can cause unpredictable behavior.
  • The SN74LS245DW can sink up to 24 mA and source up to -15 mA per output.
  • The SN74LS245DW is rated for operation up to 70°C, but it can be used in high-temperature environments up to 85°C with derated specifications.
