SN74HC174NE4 datasheet by Texas Instruments

SN74HC174NE4 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the SN74HC174NE4?
  The recommended operating voltage range for the SN74HC174NE4 is 2V to 6V, with a typical voltage of 5V.
• How do I handle the output enable (OE) pin in my design?
  The output enable (OE) pin is active-low, meaning that the outputs are enabled when OE is low and disabled when OE is high. You should connect OE to a logic low signal to enable the outputs, and to a logic high signal to disable them.
• What is the maximum clock frequency that the SN74HC174NE4 can handle?
  The maximum clock frequency that the SN74HC174NE4 can handle is 25 MHz, but this can vary depending on the operating voltage and load capacitance.
• How do I ensure that the SN74HC174NE4 is properly powered and decoupled?
  To ensure proper operation, you should provide a stable power supply voltage, and decouple the power pins with a 0.1uF ceramic capacitor. Additionally, you should also consider adding a 10uF electrolytic capacitor to further filter the power supply.
• What is the maximum current that the SN74HC174NE4 can sink or source?
  The maximum current that the SN74HC174NE4 can sink or source is 25mA per output pin, but this can vary depending on the operating voltage and temperature.
