SN74LS193D datasheet by Texas Instruments

SN74LS193D Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74LS193D can handle?
  The maximum clock frequency of the SN74LS193D is 5 MHz, but it can be operated at higher frequencies with proper signal integrity and layout considerations.
• How do I ensure that the counter is properly reset?
  To ensure proper reset, the reset input (R) should be pulled low for at least 10 ns, and then released. The counter will reset to zero when the reset input is low.
• What is the maximum count value of the SN74LS193D?
  The SN74LS193D is a 4-bit binary counter, which means it can count up to 15 (1111 in binary).
• Can I use the SN74LS193D as a divider?
  Yes, the SN74LS193D can be used as a divider by connecting the clock input to the output of a previous stage. However, the divide ratio will be limited to powers of 2 (2, 4, 8, etc.).
• How do I cascade multiple SN74LS193D counters?
  To cascade multiple counters, connect the carry-out (CO) of one counter to the clock input of the next counter. Ensure that the counters are properly synchronized and that the clock signal is properly distributed.
