CD74HC190E Frequently Asked Questions (FAQs)

  • The CD74HC190E can handle clock frequencies up to 25 MHz.
  • To ensure proper reset, connect the MR (Master Reset) pin to a 10 kΩ pull-up resistor to VCC, and then to a capacitor to ground. This will ensure that the device is properly reset during power-up.
  • The recommended operating voltage range for the CD74HC190E is 2V to 6V.
  • To cascade multiple CD74HC190E devices, connect the TC (Terminal Count) output of one device to the CP (Clock Pulse) input of the next device. This will allow the devices to count in sequence.
  • The CD74HC190E can sink or source up to 25 mA of current per output pin.
