HEF4794BP,112 datasheet by NXP Semiconductors

HEF4794BP,112 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for HEF4794BP,112?
  The recommended operating voltage range for HEF4794BP,112 is 4.5V to 15V, with a typical voltage of 5V or 10V.
• How do I handle the power-up and power-down sequences for the HEF4794BP,112?
  It's recommended to power up the VCC pin before the VDD pin, and power down the VDD pin before the VCC pin to prevent latch-up and ensure proper operation.
• What is the maximum clock frequency supported by the HEF4794BP,112?
  The maximum clock frequency supported by the HEF4794BP,112 is 10 MHz, but it's recommended to operate at a frequency below 5 MHz for reliable operation.
• How do I ensure proper noise immunity and signal integrity when using the HEF4794BP,112?
  Use proper PCB design techniques, such as separating analog and digital signals, using decoupling capacitors, and adding series resistors to the clock and data lines to reduce ringing and noise.
• Can I use the HEF4794BP,112 in a 3.3V system?
  Yes, the HEF4794BP,112 can operate at 3.3V, but the output voltage levels may not be compatible with 3.3V logic. Use level translators or voltage dividers if necessary.
