SN54LS123J Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN54LS123J is 25 MHz.
  • The SN54LS123J 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 maximum input voltage that the SN54LS123J can tolerate is 5.5V, exceeding which may cause damage to the device.
  • The asynchronous reset input (R) should be tied to VCC through a pull-up resistor (e.g., 1kΩ) to ensure proper operation. A low signal on the R input resets the counter.
  • No, the SN54LS123J is designed to operate at 5V, and using it in a 3.3V system may not guarantee proper operation or may even damage the device.
