P3A9606 2-Channel Voltage Level Translator NXP Semiconductors P3A9606 2-Channel Voltage Level Translator is a 2-bit, dual-supply translating transceiver with auto direction sensing. The P3A9606 is designed to enable bidirectional voltage level translation for traditional I2C-bus/SMBus and 12.5MHz I3C-bus applications. High-speed SPI applications are also supported when two devices are used.
