SN74HC161DR Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74HC161DR is 25 MHz.
  • To ensure proper reset, connect the MR (Master Reset) pin to a 10 kΩ pull-up resistor to VCC, and then connect it to a reset signal or a power-on reset circuit.
  • The recommended operating voltage range for the SN74HC161DR is 2 V to 6 V, with a typical operating voltage of 5 V.
  • The CLR input should be synchronized with the clock signal to avoid metastability issues. It's recommended to use a flip-flop or a synchronizer to synchronize the CLR signal with the clock.
  • The propagation delay time of the SN74HC161DR is typically around 10 ns to 15 ns, depending on the operating voltage and temperature.
