NX3V1T66
Low-ohmic single-pole single-throw analog switch
Rev. 7 — 2 November 2011
Product data sheet
1. General description
The NX3V1T66 is a low-ohmic single-pole single-throw analog switch. It has two
input/output terminals (Y and Z) and an active HIGH enable input pin (E). When pin E is
LOW, 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. A low input voltage threshold allows pin E to be driven by lower level logic
signals without a significant increase in supply current I
CC
. This makes it possible for the
NX3V1T66 to switch 4.3 V signals with a 1.8 V digital controller, eliminating the need for
logic level translation.
The NX3V1T66 allows signals with amplitude up to V
CC
to be transmitted from Y to Z or
from Z to Y. Its ultra-low ON resistance (0.3
Ω)
and flatness (0.1
Ω)
ensures minimal
attenuation and distortion of transmitted signals.

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.
Applies to control signal levels.
