NCA9306DPH

NCA9306DPH is a 2 channel bidirectional I²C and SMBus multi-voltage level translator with an enable (EN) pin input. It allows voltage translation between 0.95 V and 5V without the use of a direction pin. It supports upto 100MHz up translation and <gt/>100MHz down translation at ≤ 30pF capacitive load. There is no need for a direction pin which minimizes the system effort. It supports 5V tolerant I/O pins to support mixed mode signal operation. The ability to set up different voltage translation levels on each channel makes the device very flexible and suitable for a lot of different applications. The low ON-state resistance RON of the switch allows connections to be made with minimal propagation delay. It is used in applications such as GPIO, MDIO, PMBus, SMBus, SDIO, UART, I²C, and other interfaces in telecom infrastructure, industrial, personal computing, router and industrial automation.
