Overview
●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.
