SN74LS390NSR Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the SN74LS390NSR is 30 MHz, but it can vary depending on the specific application and operating conditions.
  • To ensure reliable operation in high-temperature environments, it is recommended to follow proper thermal management practices, such as providing adequate heat sinking and airflow, and ensuring that the device is operated within its specified temperature range (-40°C to 85°C).
  • The recommended power-on sequence for the SN74LS390NSR is to apply power to the VCC pin before applying any input signals, and to ensure that the input signals are stable before applying clock signals.
  • To handle bus contention when using the SN74LS390NSR as a bus transceiver, it is recommended to use bus termination resistors and to ensure that the bus is properly terminated to prevent reflections and signal degradation.
  • The maximum capacitive load that the SN74LS390NSR can drive is 100 pF, but it can vary depending on the specific application and operating conditions.
