SN74LS123NSR Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74LS123NSR is 2 MHz, but it can be operated at higher frequencies with proper signal conditioning and layout.
  • The SN74LS123NSR requires a single 5V power supply, and it's recommended to use a decoupling capacitor of 0.1uF to 1uF between VCC and GND to reduce noise and ensure stable operation.
  • The SN74LS123NSR can sink or source up to 16mA per output, but it's recommended to limit the current to 10mA per output to ensure reliable operation.
  • The SN74LS123NSR has an active-low reset input (R) that can be used to reset the device. To reset the device, pull the R input low for at least 10ns.
  • The propagation delay of the SN74LS123NSR is typically around 10ns to 20ns, depending on the operating conditions and load capacitance.
