Overview
The NTSX2102GU8H, manufactured by NXP USA Inc., is a 2-bit, dual supply translating transceiver with auto direction sensing. This device is designed to enable bidirectional voltage level translation between different voltage domains, making it highly versatile for various electronic systems. It features two 2-bit input-output ports (An and Bn), one output enable input (OE), and two supply pins (VCC(A) and VCC(B)) that can operate within a wide voltage range of 1.65 V to 5.5 V. This flexibility allows the device to translate between common voltage nodes such as 1.8 V, 2.5 V, 3.3 V, and 5.0 V.
