The UM3A9606 is a 2-bit, dual-supply bidirectional I2C, I3C, SMBus and SPI voltage-level translator with auto direction sensing. The device features one output enable input (OE) and 0.72V to 1.98V power supply on both A-side and B-side which makes it suitable for low voltage nodes (0.8V, 1.2V, 1.8V). In addition, VCCA must be ≤ VCCB for proper operation.
The UM3A9606 can be used for both open-drain and push-pull application which is compatible with I2 C, 12.5 MHz I3C-Bus applications and higher speed SPI applications.
Pins An are referenced to VCCA and Pins Bn are referenced to VCCA. The OE pin is referenced to VCCA and set to low to place An and Bn pins in high-impendence state. The device also supports partial power-down applications using IOFF. The IOFF circuit disables the outputs to prevent the backflow current through the device.
- 2-bit, dual-supply bidirectional translator for I2C, I3C, SMBus and SPI applications
- Wide supply voltage:
-- VCCA: 0.72 V to 1.98V
-- VCCB: 0.72 V to 1.98V, VCCA ≤ VCCB
- Compatible with MIPI I3C supporting speeds up to 12.5MHz
- IOFF supports partial power-down mode operation
- VCC isolation feature – if either VCC input is at GND, all are in the high-impedance state
