The NX3L1G3157 is a low-ohmic single-pole double-throw analog switch suitable for use
as an analog or digital 2:1 multiplexer/demultiplexer. It has a digital select input (S), two
independent inputs/outputs (Y0 and Y1) and a common input/output (Z). Schmitt trigger
action at the digital input makes the circuit tolerant to slower input rise and fall times.
The NX3L1G3157 allows signals with amplitude up to VCC to be transmitted from Z to Y0
or Y1; or from Y0 or Y1 to Z. Its low ON resistance (0.5 Ω) and flatness (0.13 Ω) ensures
minimal attenuation and distortion of transmitted signals.
