MC74HC161ADG Frequently Asked Questions (FAQ)

  • The maximum clock frequency of the MC74HC161ADG is 25 MHz, but it can vary depending on the operating voltage and temperature. It's recommended to check the timing characteristics in the datasheet for specific frequency limits.

  • To ensure proper reset, connect the MR (Master Reset) pin to a pull-up resistor and a capacitor to VCC. This will ensure that the device is reset during power-up and holds the reset state until the capacitor is fully charged.

  • The recommended operating voltage range for the MC74HC161ADG is 2.0 V to 6.0 V, with a typical operating voltage of 5.0 V. Operating the device outside of this range may affect its performance and reliability.

  • The CLR input should be tied to VCC or a logic high level during normal operation to prevent accidental clearing of the counter. If you need to clear the counter during operation, use a synchronous clear method by clocking in a clear signal through the clock input.

  • The maximum output current that the MC74HC161ADG can sink or source is 25 mA per output pin. Exceeding this limit may cause damage to the device or affect its reliability.
