The NX3L1T66 provides one single-pole single-throw analog switch function. It has two input/output terminals (Yand Z) and an active HIGH enable input pin (E). When 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 NX3L1T66 to switch 4.3 V signals with a 1.8 V digital controller, eliminating the need for logic level translation.
The NX3L1T66 allows signals with amplitude up to VCC to be transmitted from nY to nZ; or from nZ to nY. Its low ON resistance (0.5 Ω) and flatness (0.13 Ω) ensures minimal attenuation and distortion of transmitted signals.
