1. General description
The NX3L2G384 is a dual low-ohmic single-pole single-throw analog switch. Each switch
has two input/output terminals (nY and nZ) and an active LOW enable input (nE
). When
pin nE
is HIGH, the analog switch is turned off.
Schmitt trigger action at the enable input (nE
) makes the circuit tolerant to slower input
rise and fall times. The NX3L2G384 allows signals with amplitude up to V
CC
to be
transmitted from nY to nZ; or from nZ to nY. Its low ON resistance (0.5 ) and flatness
(0.13 ) ensures minimal attenuation and distortion of transmitted signals.
