SN74LS193DR Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74LS193DR is 25 MHz.
  • To ensure proper reset, the reset input (R) should be pulled low for at least 10 ns. The counter will reset to 0 when the reset input is low.
  • The maximum count value of the SN74LS193DR is 255 (all 8 bits set).
  • Yes, the SN74LS193DR can be used as a down-counter by connecting the QA output to the CI input and using the LD input to load the initial count value.
  • To cascade multiple counters, connect the QA output of the first counter to the CI input of the second counter, and so on. Ensure that the clock inputs are connected in parallel.
