PCA9306DCTR datasheet by Texas Instruments

PCA9306DCTR Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for PCA9306DCTR?
  The maximum frequency of operation for PCA9306DCTR is 400 kHz, but it can be operated at higher frequencies with reduced voltage translation.
• How do I ensure signal integrity when using PCA9306DCTR?
  To ensure signal integrity, use a low-ESR capacitor (e.g., 0.1 μF) between VCCA and GND, and VCCB and GND, and keep the PCB traces as short as possible.
• Can I use PCA9306DCTR for level-shifting between 1.8V and 5V?
  Yes, PCA9306DCTR can be used for level-shifting between 1.8V and 5V, but ensure that the input voltage does not exceed the maximum rating of 5.5V.
• What is the maximum current that PCA9306DCTR can sink or source?
  The maximum current that PCA9306DCTR can sink or source is 8 mA, but it's recommended to limit the current to 4 mA for reliable operation.
• How do I handle ESD protection when using PCA9306DCTR?
  PCA9306DCTR has built-in ESD protection, but it's still recommended to use external ESD protection devices, such as TVS diodes, to protect against high-voltage transients.
