Overview
The NTSX2102GU8X, produced by NXP USA Inc., is a 2-bit, dual supply translating transceiver designed for bidirectional voltage level translation. This device features auto direction sensing, enabling it to automatically determine the direction of data flow between two different voltage domains. It is particularly useful in systems where different voltage levels are used, such as in I2C, SMBus, UART, and GPIO interfaces. The NTSX2102GU8X supports a wide supply voltage range from 1.65 V to 5.5 V for both VCC(A) and VCC(B), making it versatile for various applications.
