The NX3DV2567GU is a four-pole double-throw (4PDT) Analog Switch optimized for switching WLAN-SIM supply, data and control signals. It has one digital select input (S) and four switches each with two independent input/outputs (nY0 and nY1) and a common input/output (nZ). Schmitt trigger action at S makes the circuit tolerant to slower input rise and fall times across the entire VCC range from 1.4 to 4.3V. A low input voltage threshold allows pin S to be driven by lower level logic signals without significant increase in supply current ICC. This makes it possible for the NX3DV2567 to switch 4.3V signals with a 1.8V digital controller, eliminating the need for logic level translation. It allows signals with amplitude up to VCC to be transmitted from nZ to nY0 or nY1 or from nY0 or nY1 to nZ.
