SN74HC193DR datasheet by Texas Instruments

SN74HC193DR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74HC193DR can handle?
  The SN74HC193DR can handle clock frequencies up to 30 MHz.
• How do I ensure that the counter is properly reset?
  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.
• What is the maximum count value that the SN74HC193DR can store?
  The SN74HC193DR is a 4-bit binary counter, so it can store a maximum count value of 15 (1111 in binary).
• Can I use the SN74HC193DR as a synchronous counter?
  Yes, the SN74HC193DR can be used as a synchronous counter. The clock input (CP) is synchronized with the internal clock, allowing for synchronous counting.
• How do I cascade multiple SN74HC193DR counters?
  To cascade multiple SN74HC193DR counters, connect the carry-out (CO) of one counter to the clock input (CP) of the next counter, and ensure that the reset inputs (R) are connected together.
