NX3L1T384
Low-ohmic single-pole single-throw analog switch
Rev. 01 — 29 September 2009
Product data sheet
1. General description
The NX3L1T384 provides one single-pole single-throw analog switch function. It has two
input/output terminals (Y and Z) and an active LOW enable input pin (E). When E is HIGH,
the analog switch is turned off.
Schmitt trigger action at the 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 pin E to be driven by lower level logic signals without
a significant increase in supply current ICC. This makes it possible for the NX3L1T384 to
switch 4.3 V signals with a 1.8 V digital controller, eliminating the need for logic level
translation.
The NX3L1T384 allows signals with amplitude up to VCC to be transmitted from Y to Z; or
from Z to Y. Its low ON resistance (0.5 ) and flatness (0.13 ) ensures minimal
attenuation and distortion of transmitted signals.

[1] The minimum input voltage rating may be exceeded if the input current rating is observed.
[2] The minimum and maximum switch voltage ratings may be exceeded if the switch clamping current rating is observed but may not
exceed 4.6 V.
[3] For TSSOP5 package: above 87.5 °C the value of Ptot derates linearly with 4.0 mW/K.
For XSON6 package: above 118 °C the value of Ptot derates linearly with 7.8 mW/K.

[1] To avoid sinking GND current from of terminal Z when switch current flows in terminal Y, the voltage drop across the bidirectional switch
must not exceed 0.4 V. If the switch current flows into terminal Z, no GND current will flow from terminal Y. In this case, there is no limit
for the voltage drop across the switch.
[2] Applies to control signal levels.
