The NX3DV2567-Q100 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.
Lower-level logic signals can drive pin S without a significant increase in supply current ICC, due to a low input voltage threshold. This characteristic makes it possible for the NX3DV2567-Q100 to switch 4.3 V signals with a 1.8 V digital controller, eliminating the need for logic level translation.
The NX3DV2567-Q100 allows signals with amplitude up to VCC to be transmitted from nZ to nY0 or nY1; or from nY0 or nY1 to nZ.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
