The NX3V1T66 provides one single-pole single-throw analog switch function. It has two input/output terminals (Y and Z) and an active HIGH enable input pin (E). When pin E is LOW, the analog switch is turned off.
Schmitt trigger action at the enable input (E) 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 E to be driven by lower level logic signals without a significant increase in supply current ICC. This makes it possible for the NX3V1T66 to switch 4.3 V signals with a 1.8 V digital controller, eliminating the need for logic level translation.
The NX3V1T66 allows signals with amplitude up to VCC to be transmitted from Y to Z or from Z to Y. Its ultra-low ON resistance (0.3 Ω) and flatness (0.1 Ω) ensures minimal attenuation and distortion of transmitted signals.
