NX3L1G3157
Low-ohmic single-pole double-throw analog switch
Rev. 08 — 26 April 2010
Product data sheet
1. General description
The NX3L1G3157 is a low-ohmic single-pole double-throw analog switch suitable for use
as an analog or digital 2:1 multiplexer/demultiplexer. It has a digital select input (S), two
independent inputs/outputs (Y0 and Y1) and a common input/output (Z). Schmitt-trigger
action at the digital input makes the circuit tolerant to slower input rise and fall times.
The NX3L1G3157 allows signals with amplitude up to V
CC
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.
2. Features and benefits
Wide supply voltage range from 1.4 V to 4.3 V

To avoid sinking GND current from terminal Z when switch current flows in terminal Yn, 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 Yn. In this case, there is no limit
for the voltage drop across the switch.
Applies to control signal levels.
