M74HC173RM13TR Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the M74HC173RM13TR?
  The recommended operating voltage range for the M74HC173RM13TR is 2V to 6V, with a typical voltage of 5V.
• How do I handle the asynchronous clear input (CLR) in my design?
  The asynchronous clear input (CLR) should be tied to VCC or GND through a pull-up or pull-down resistor, respectively, to ensure proper operation. A 1kΩ to 10kΩ resistor is recommended.
• What is the maximum clock frequency supported by the M74HC173RM13TR?
  The maximum clock frequency supported by the M74HC173RM13TR is 25 MHz, but it can vary depending on the operating voltage and load conditions.
• How do I ensure proper power sequencing when using the M74HC173RM13TR in my design?
  To ensure proper power sequencing, the VCC pin should be powered up before the clock (CLK) and data (D) inputs. Also, the VCC pin should be powered down after the clock and data inputs.
• What is the purpose of the output enable (OE) input, and how do I use it?
  The output enable (OE) input is used to enable or disable the output buffers. When OE is low, the outputs are enabled, and when OE is high, the outputs are high-impedance (tri-stated).
