SN54LS393J Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN54LS393J is 40 MHz.
  • To ensure proper reset, connect the CLR (clear) input to a 1KΩ pull-up resistor to VCC, and add a 0.1μF capacitor between CLR and GND to filter out noise.
  • Yes, you can use the SN54LS393J as a divide-by-2 counter by connecting the Q3 output to the CLK input, and using the Q0 output as the divided clock signal.
  • To cascade multiple counters, connect the Q3 output of one counter to the CLK input of the next counter, and connect the CLR inputs of all counters together to a common reset signal.
  • The maximum output current that the SN54LS393J can sink or source is 16mA.
