Description
The NX3DV2567 is a four-pole double-throw analog switch (4PDT) 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 V to 4.3 V. 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 4.3 V signals with a 1.8 V digital controller, eliminating the need for logic level translation. The NX3DV2567 allows signals with amplitude up to VCC to be transmitted from nZ to nY0 or nY1; or from nY0 or nY1 to nZ..
