The NX3L1T53 is a low-ohmic single-pole double-throw analog switch suitable for use as
an analog or digital 2:1 multiplexer/demultiplexer. It has a digital select input (S), two
independent inputs/outputs (Y0 and Y1), a common input/output (Z) and an active LOW
enable input (E). When pin E is HIGH, the switch is turned off.
Schmitt trigger action at the digital inputs makes the circuit tolerant to slower input rise and
fall times. Low threshold digital inputs allows this device to be driven by 1.8 V logic levels
in 3.3 V applications without significant increase in supply current ICC. This makes it
possible for the NX3L1T53 to switch 4.3 V signals with a 1.8 V digital controller,
eliminating the need for logic level translation. The NX3L1T53 allows signals with
amplitude up to VCC to be transmitted from Z to Y0 or Y1; or from Y0 or Y1 to Z. It’s low
ON resistance (0.5 Ω) and flatness (0.13 Ω) ensures minimal attenuation and distortion of
