NX3L4357: Low-ohmic single-pole triple-throw analog switch with enable input
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. This makes it
possible for the NX3L4357 to switch 4.3 V signals with a 1.8 V digital controller,
eliminating the need for logic level translation. 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.
