SN74109N datasheet by Texas Instruments

SN74109N Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74109N can handle?
  The maximum clock frequency of the SN74109N is 10 MHz, but it can operate at higher frequencies with reduced voltage and/or lower temperatures.
• How do I ensure proper power sequencing when using the SN74109N?
  To ensure proper power sequencing, apply power to the VCC pin before applying a clock signal to the CLK pin. Also, ensure that the VCC pin is stable before applying any input signals.
• What is the recommended operating voltage range for the SN74109N?
  The recommended operating voltage range for the SN74109N is 4.5V to 5.5V, with a typical operating voltage of 5V.
• How do I handle the asynchronous reset input (RST) on the SN74109N?
  The RST input is active-low, meaning it should be pulled low to reset the device. When RST is low, all outputs are reset to a low state. When RST returns high, the device resumes normal operation.
• What is the purpose of the MR (Master Reset) input on the SN74109N?
  The MR input is used to reset the internal counters and flip-flops of the device. When MR is low, the device is reset, and all counters and flip-flops are cleared.
