RS0101 1-Bit Bidirectional Voltage-Level Translator for OpenDrain and Push-Pull Application FEATURES • • • • • • • DESCRIPTION No Direction-Control Data Rates 24Mbps (Push-Pull) 2Mbps (Open-Drain) 1.65V to 5.5V on A ports and 2.3V to 5.5V on B Ports (VCCA≤VCCB) VCC Isolation: If Either VCC is at GND, Both Ports are in the High-Impedance State No Power-Supply Sequencing Required: Either VCCA or VCCB can be Ramped First IOFF: Supports Partial-Power-Down Mode Operation Extended Temperature: -40°C to +85°C APPLICATIONS • • • I2C/ SMBus UART GPIO This 1-bit non-inverting translator is a bidirectional voltagelevel translator and can be used to establish digital switching compatibility between mixed-voltage systems. It uses two separate configurable power-supply rails, with the A ports supporting operating voltages from 1.65V to 5.5V while it tracks the VCCA supply, and the B ports supporting operating voltages from 2.3V to 5.5V while it tracks the VCCB supply. This allows the support of both lower and higher logic signal levels while providing bidirectional translation capabilities between any of the 1.8V, 2.5V, 3.3V and 5V voltage nodes. When the output-enable (OE) input is low, all I/Os are placed in the high-impedance state, which significantly reduces the power-supply quiescent current consumption. OE has an internal pull-down current source, as long as VCCA is powered. To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver. The RS0101 is available in Green SOT23-6 、 SOT363(SC70-6) and DFN1.45x1.0-6L packages. It operates over an ambient temperature range of -40°C to +85°C.
