Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DGKR' corresponds to the 8-VSSOP package and tape-and-reel packaging format. Confirm that the VCCA and VCCB supply requirements align with your system's voltage rails, as the device supports distinct voltage ranges for each side. Ensure compatibility with FM+ signaling standards if high-speed operation is required. Check RoHS3 compliance status for environmental regulations.

Translators, Level Shifters Selection Notes

Select this component when designing systems that require bridging low-voltage controllers with higher-voltage peripherals on shared I2C or SMBus lines. The wide VCCA range allows integration with modern low-power microcontrollers, while the VCCB range accommodates traditional 3.3V or 5V buses. Consider the 8-VSSOP package size for space-constrained PCB layouts. Verify that the open-drain output structure matches the pull-up resistor configuration of your target bus.
