M74HC160RM13TR Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the M74HC160RM13TR?
  The recommended operating voltage range for the M74HC160RM13TR is 2V to 6V, with a typical voltage of 5V.
• How do I handle the asynchronous reset input (MR) in my design?
  The asynchronous reset input (MR) should be tied to VCC through a pull-up resistor (e.g., 1 kΩ) to ensure proper operation. A low level on MR resets the counter.
• What is the maximum clock frequency supported by the M74HC160RM13TR?
  The maximum clock frequency supported by the M74HC160RM13TR is 25 MHz at VCC = 5V and 10 MHz at VCC = 3.3V.
• How do I ensure proper synchronization of the clock input (CP) with the internal clock?
  The clock input (CP) should be synchronized with the internal clock by using a clock buffer or a clock synchronization circuit to minimize clock skew and ensure reliable operation.
• What is the purpose of the enable input (EN) in the M74HC160RM13TR?
  The enable input (EN) allows the counter to be enabled or disabled. When EN is high, the counter is enabled, and when EN is low, the counter is disabled and the outputs are in a high-impedance state.
