Overview
The NX3L1T3157GM,132 is a 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 a digital select input (S), two independent inputs/outputs (Y0 and Y1), and a common input/output (Z). The device is notable for its Schmitt trigger action at the digital input, which makes it tolerant to slower input rise and fall times. This allows the switch to be driven by 1.8 V logic levels in 3.3 V applications without a significant increase in supply current.
