SN74LS122DR Frequently Asked Questions (FAQs)

  • The maximum frequency of operation for the SN74LS122DR is 35 MHz.
  • No, the SN74LS122DR is a 5V device and is not compatible with 3.3V systems. You may need to use a level shifter or a different device that is compatible with 3.3V systems.
  • The SN74LS122DR does not have any specific power-up or power-down sequencing requirements. However, it is recommended to power up the device slowly (within 10 ms) to prevent any potential latch-up or damage to the device.
  • The SN74LS122DR can sink up to 24 mA and source up to 12 mA per output.
  • The SN74LS122DR is rated for operation up to 70°C. However, the device's performance and reliability may degrade at higher temperatures. It is recommended to use a heat sink or to derate the device's operating frequency at higher temperatures.
