1. General description
The NX3DV2567 is a four-pole double-throw analog switch (4PDT) optimized for
switching WLAN-SIM supply, data and control signals. It has one digital select input (S)
and four switches each with two independent input/outputs (nY0 and nY1) and a common
input/output (nZ). Schmitt trigger action at S makes the circuit tolerant to slower input rise
and fall times across the entire V
CC
range from 1.4 V to 4.3 V.
A low input voltage threshold allows pin S to be driven by lower level logic signals without
significant increase in supply current I
CC
. This makes it possible for the NX3DV2567 to
switch 4.3 V signals with a 1.8 V digital controller, eliminating the need for logic level
translation.
The NX3DV2567 allows signals with amplitude up to V
CC
to be transmitted from nZ to nY0
or nY1; or from nY0 or nY1 to nZ..
