SN74LS21DR Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the SN74LS21DR is 25 MHz.
  • The SN74LS21DR is compatible with 5V logic, but it is not recommended for use with 3.3V logic due to its limited output drive capability.
  • The typical power consumption of the SN74LS21DR is 20 mW, but it can vary depending on the operating frequency and load conditions.
  • The SN74LS21DR is rated for operation up to 70°C, but it can be used in high-temperature environments up to 85°C with some derating of the operating frequency.
  • No, the SN74LS21DR is not radiation-hardened and is not suitable for use in high-radiation environments.
