HEF40175BT,653 datasheet by NXP Semiconductors

HEF40175BT,653 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the HEF40175BT,653?
  The recommended operating voltage range for the HEF40175BT,653 is 4.5V to 15.5V, with a typical voltage of 5V or 10V.
• How do I ensure proper power sequencing when using the HEF40175BT,653?
  To ensure proper power sequencing, apply the power supply voltage (VCC) before applying any input signals, and ensure that the input signals are stable before applying the clock signal.
• What is the maximum clock frequency supported by the HEF40175BT,653?
  The maximum clock frequency supported by the HEF40175BT,653 is 10 MHz, but it can operate at frequencies up to 20 MHz with reduced voltage and load capacitance.
• How do I handle the asynchronous reset input (MR) in the HEF40175BT,653?
  The asynchronous reset input (MR) should be tied to VCC through a pull-up resistor (e.g., 1 kΩ) to ensure proper reset functionality. A low-level input on MR resets the device.
• What is the purpose of the output enable input (OE) in the HEF40175BT,653?
  The output enable input (OE) is used to tri-state the outputs, allowing multiple devices to share the same bus. A low-level input on OE enables the outputs, while a high-level input tri-states them.
