SN74HC161PW Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74HC161PW is 25 MHz.
  • To ensure proper reset, connect the MR (Master Reset) pin to a 10 kΩ pull-up resistor to VCC, and add a 0.1 μF capacitor between MR and GND to filter out noise.
  • The recommended operating voltage range for the SN74HC161PW 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. Use a flip-flop or a synchronizer circuit to synchronize the CLR signal with the clock.
  • The maximum propagation delay time for the SN74HC161PW is 35 ns (typical) and 50 ns (maximum) at 25°C and 5 V supply voltage.
