1. General description
The NX3L1G3157-Q100 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-Q100 allows signals with amplitude up to V
CC
to be transmitted from Z
to Y0 or Y1; or from Y0 or Y1 to Z. Its low ON resistance (0.5 ) and flatness (0.13 )
ensures minimal attenuation and distortion of transmitted signals.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
