General description
●The NX3L4684 provides two low-ohmic single-pole double-throw analog switches, suitable for use as an analog or digital multiplexer/demultiplexer. It has a digital select input (nS) with Schmitt trigger action, two independent inputs/outputs (nY0, nY1) and a common input/output (nZ). Schmitt trigger action at the select input (nS) makes the circuit tolerant to slower input rise and fall times across the entire VCC range from 1.4 V to 4.3 V.
●A low input voltage threshold allows pin nS to be driven by lower level logic signals without a significant increase in supply current ICC. This makes it possible for the NX3L4684 to switch 4.3 V signals with a 1.8 V digital controller, eliminating the need for logic level translation.
●Features
