General description The NX3L4357 is a low-ohmic single-pole triple-throw analog switch suitable for use as an analog or digital 3:1 multiplexer/demultiplexer. It has two digital select inputs (S0 and S1), one digital enable input (E), three independent inputs/outputs (Y0, Y1 and Y2) and a common input/output (Z). The device features a broadcast mode, when S0 and S1 are both high the signal applied to pin Z is passed to Y0, Y1 and Y2. Schmitt trigger action at the digital inputs makes the circuit tolerant to slower input rise and fall times. Low threshold digital inputs allows this device to be driven by 1.8 V logic levels in 3.3 V applications without signiﬁcant increase in supply current ICC. The NX3L4357 allows signals with amplitude up to VCC to be transmitted from Z to Yn or Yn to Z. Its low ON resistance (0.5 Ω) and ﬂatness (0.13 Ω) ensures minimal attenuation and distortion of transmitted signals. 2.

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.
