SN75C189DR Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the SN75C189DR is 100 MHz.
  • Yes, the SN75C189DR is compatible with 3.3V systems, but it can also operate at 5V. However, the output voltage swing will be reduced at 3.3V.
  • To ensure reliable operation in high-temperature environments, make sure to follow proper thermal management practices, such as providing adequate heat sinking and airflow. Also, ensure that the device is operated within its recommended operating temperature range of -40°C to 85°C.
  • The typical propagation delay of the SN75C189DR is around 10 ns.
  • Yes, the SN75C189DR can be used as a level translator between 5V and 3.3V logic. However, note that the output voltage swing will be reduced when translating from 5V to 3.3V.
