CD74HC194M datasheet by Texas Instruments

CD74HC194M Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the CD74HC194M?
  The maximum clock frequency for the CD74HC194M is 25 MHz, but it can vary depending on the operating voltage and temperature. It's recommended to check the timing diagrams and specifications in the datasheet for more information.
• Can I use the CD74HC194M with a 5V power supply?
  Yes, the CD74HC194M can operate with a 5V power supply, but it's recommended to use a 2.0V to 6.0V power supply for optimal performance. The device is also compatible with 3.3V and 1.8V power supplies.
• How do I reset the CD74HC194M?
  The CD74HC194M has a Master Reset (MR) input that can be used to reset the device. When the MR input is low, the device is reset and all outputs are set to a low state. The MR input should be tied to VCC through a pull-up resistor if it's not used.
• What is the propagation delay time for the CD74HC194M?
  The propagation delay time for the CD74HC194M varies depending on the operating voltage and temperature. At 25°C and 5V, the typical propagation delay time is around 15 ns. Check the datasheet for more information on propagation delay times at different operating conditions.
• Can I use the CD74HC194M in a high-temperature environment?
  The CD74HC194M is rated for operation from -40°C to 125°C, but it's recommended to derate the device for high-temperature operation. Check the datasheet for more information on temperature derating and thermal characteristics.
