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 VCC 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.
