DS1746-70+ Frequently Asked Questions (FAQ)

  • The recommended power-up sequence is to apply VCC first, followed by VPP, and then VDD. This ensures proper initialization of the device.

  • To ensure data integrity, use a low-pass filter on the VCC and VDD pins to reduce noise, and consider using a capacitor on the VPP pin to filter out high-frequency noise.

  • The maximum clock frequency is 10 MHz, but it's recommended to operate at a frequency below 5 MHz to ensure reliable operation.

  • Yes, the DS1746-70+ can operate from a 3.3V supply, but the VPP pin should be connected to a 5V supply or a voltage regulator to ensure proper operation.

  • If the device is not responding, try resetting the device by toggling the RST pin low and then high. If the issue persists, check the power supply and clock signals for any issues.
