NX3L1T5157
Low-ohmic single-pole double-throw switch
Rev. 01 — 16 September 2008

1. General description
The NX3L1T5157 provides one low-ohmic single-pole double-throw analog switch,
suitable for use as an analog or digital multiplexer/demultiplexer. It has a digital select
input (S) with Schmitt trigger action, two independent inputs/outputs (Y0, Y1) and a
common input/output (Z).
Schmitt trigger action at the select input (S) makes the circuit tolerant to slower input rise
and fall times across the entire VCC range from 1.4 V to 3.6 V.
A low input voltage threshold allows pin S to be driven by lower level logic signals without
a significant increase in supply current ICC. This makes it possible for the NX3L1T5157 to
switch 3.6 V signals with a 1.8 V digital controller, eliminating the need for logic level
translation.
The NX3L1T5157 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 Ω) and flatness (0.13 Ω) ensures
minimal attenuation and distortion of transmitted signals.
