Frequently Asked Questions
What voltage levels does PCA9517DGKR support?
PCA9517DGKR supports dual-supply operation: V1 (1.8V to 3.3V) on one side and V2 (2.5V to 5.5V) on the other, making it ideal for translating I2C signals between 1.8V/3.3V microcontrollers and 5V peripherals.
What is the maximum I2C speed for PCA9517DGKR?
PCA9517DGKR supports both Standard-mode (100kHz) and Fast-mode (400kHz) I2C communication. It does not support Fast-mode Plus (1MHz).
What package does PCA9517DGKR come in?
PCA9517DGKR comes in a VSSOP-8 (8-pin Very Thin Shrink Small Outline Package) with a 0.65mm pitch. The 'DGKR' suffix indicates the VSSOP-8 package on tape-and-reel.
What are good alternatives to PCA9517DGKR?
Compatible alternatives include PCA9517ADGKR (automotive grade, AEC-Q100), TCA9406DCUR (TI 6-pin VSSOP I2C level shifter), and P82B715TD (NXP I2C bus extender for 100kHz/400kHz).
Is PCA9517DGKR RoHS compliant?
Yes, PCA9517DGKR is fully RoHS compliant and lead-free. It carries an MSL1 moisture sensitivity level rating, requiring no special dry-pack storage.
