SN74LS245DW Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the SN74LS245DW?
  The maximum frequency of operation for the SN74LS245DW is 30 MHz.
• Can I use the SN74LS245DW in a 3.3V system?
  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.
• How do I handle the enable inputs (G1 and G2) when not in use?
  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.
• What is the maximum current that the SN74LS245DW can sink or source?
  The SN74LS245DW can sink up to 24 mA and source up to -15 mA per output.
• Can I use the SN74LS245DW in a high-temperature environment?
  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.
