Product data sheet
1. General description
The NX3L4684 provides two low-ohmic single-pole double-throw analog switches,
suitable for use as an analog or digital multiplexer/demultiplexer. It has a digital select
input (nS) with Schmitt trigger action, two independent inputs/outputs (nY0, nY1) and a
common input/output (nZ). Schmitt trigger action at the select input (nS) 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 nS to be driven by lower level logic signals without
a significant increase in supply current I_CC. This makes it possible for the NX3L4684 to
switch 4.3 V signals with a 1.8 V digital controller, eliminating the need for logic level
translation.
The NX3L4684 allows signals with amplitude up to V_CC to be transmitted from nZ to nY0
or nY1; or from nY0 or nY1 to nZ. Its low ON resistance (0.3 Ω for Y0 port, 0.5 Ω for Y1
port) and flatness (0.1 Ω) ensures minimal attenuation and distortion of transmitted
signals.
