CD74HC4040E datasheet by Texas Instruments

CD74HC4040E Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD74HC4040E can handle?
  The CD74HC4040E can handle clock frequencies up to 10 MHz.
• How do I reset the counter?
  The CD74HC4040E has an asynchronous reset input (MR) that can be used to reset the counter. When the MR input is low, the counter is reset to zero.
• What is the maximum count value of the CD74HC4040E?
  The CD74HC4040E is a 12-bit binary counter, which means it can count up to 4095 (2^12 - 1).
• Can I use the CD74HC4040E as a frequency divider?
  Yes, the CD74HC4040E can be used as a frequency divider. By connecting the Q12 output to the clock input, the device can be used to divide the input clock frequency by 2, 4, 8, or any other power of 2 up to 4096.
• What is the power consumption of the CD74HC4040E?
  The power consumption of the CD74HC4040E depends on the operating frequency and voltage. According to the datasheet, the typical power consumption is 10 μW at 1 MHz and 5V supply voltage.
