NX3L1T53
Low-ohmic single-pole double-throw analog switch
Rev. 02 — 14 April 2009

1. General description
The NX3L1T53 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),
two independent inputs/outputs (Y0, Y1), a common input/output (Z) and an active LOW
enable input (E). When pin E is HIGH, the switch is turned off. Schmitt-trigger action at the
select input (S) and enable input (E) makes the circuit tolerant to slower input rise and fall
times across the entire VCC range from 1.4 V to 4.3 V.
A low input voltage threshold allows pins S and E to be driven by lower level logic signals
without a significant increase in supply current ICC. This makes it possible for the
NX3L1T53 to switch 4.3 V signals with a 1.8 V digital controller, eliminating the need for
logic level translation.
The NX3L1T53 allows signals with amplitude up to VCC to be transmitted from Z to Y0 or
Y1; or from Y0 or Y1 to Z. It’s low ON resistance (0.5 Ω) and flatness (0.13 Ω) ensures
minimal attenuation and distortion of transmitted signals.
