Overview
The NX3L1T5157GMZ is a low-ohmic single-pole double-throw analog switch manufactured by NXP USA Inc. This device is designed for use as an analog or digital 2:1 multiplexer/demultiplexer. It features a digital select input (S), two independent inputs/outputs (Y0 and Y1), and a common input/output (Z). The NX3L1T5157GMZ is notable for its Schmitt trigger action at the digital input, which makes the circuit tolerant to slower input rise and fall times. Additionally, it can be driven by 1.8 V logic levels in 3.3 V applications without a significant increase in supply current, eliminating the need for logic level translation.
