RS0102
Every spec below is cited to the manufacturer datasheet. Pick your exact ordering code, compare the closest alternatives, then ask the assistant what it means for your design.
What the RS0102 family does
The RS0102 is a 2-bit bidirectional voltage-level translator designed for open-drain and push-pull applications. It supports data rates up to 24 Mbps for push-pull outputs and 2 Mbps for open-drain configurations. The device operates across a wide voltage range, handling 1.65V to 5.5V on the A ports and 2.3V to 5.5V on the B ports without requiring power-supply sequencing. It features a partial-power-down mode to reduce quiescent current and supports extended temperatures from -40°C to +85°C. Engineers typically use this component for I2C/SMBus, UART, and GPIO interfaces to establish digital switching compatibility between mixed-voltage systems. Available in Green SOT-23-8 and VSSOP-8 packages, the RS0102 facilitates seamless communication between 1.8V, 2.5V, 3.3V, and 5V nodes.
