SN74ALS193AN Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74ALS193AN is 30 MHz.
  • To ensure proper reset, the reset input (R) should be held low for at least 10 ns, and then released to allow the counter to start counting.
  • The maximum count value of the SN74ALS193AN is 65535 (FFFFh).
  • Yes, the SN74ALS193AN can be used as a synchronous counter by connecting the clock input (CLK) to the clock signal and the enable input (EN) to the enable signal.
  • To cascade multiple SN74ALS193AN counters, connect the carry-out (CO) of one counter to the clock input (CLK) of the next counter, and connect the enable input (EN) of each counter to the enable signal.
