CD74HC194PW Frequently Asked Questions (FAQs)

  • The maximum clock frequency for the CD74HC194PW is 25 MHz, but it can vary depending on the operating voltage and temperature. It's recommended to check the timing diagrams and switching characteristics in the datasheet for more information.
  • The CD74HC194PW can be used as both a 4-bit counter and a 4-bit shift register. The device has a counter mode and a shift register mode, which can be selected using the MODE input pin.
  • The CD74HC194PW has a asynchronous reset input (R) that can be used to reset the device. When the R input is low, the device is reset and the outputs are set to zero.
  • The power consumption of the CD74HC194PW depends on the operating frequency, voltage, and temperature. According to the datasheet, the typical power consumption is around 10 μW at 1 MHz and 5V supply voltage.
  • The CD74HC194PW is designed to operate with a 2V to 6V supply voltage range, which includes 3.3V and 1.8V. However, the device's performance and power consumption may vary at lower supply voltages.
