Overview
The NX3L2267GU,115 is a dual low-ohmic single-pole double-throw (SPDT) analog switch produced by NXP USA Inc. This component is designed for use as an analog or digital 2:1 multiplexer/demultiplexer. It features Schmitt trigger action at the digital inputs, making the circuit tolerant to slower input rise and fall times. This allows the device to be driven by 1.8 V logic levels in 3.3 V applications without a significant increase in supply current.
