Low-ohmic single-pole double-throw analog switch

Rev. 6 â 8 November 2011

Product data sheet

1. General description

The NX3L1T5157 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) and a common input/output (Z).

Schmitt trigger action at the digital input makes the circuit tolerant to slower input rise and

fall times. Low threshold digital input 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 NX3L1T5157 to switch 4.3 V signals with a 1.8 V digital controller, eliminating the

need for logic level translation. The NX3L1T5157 allows signals with amplitude up to VCC

to be transmitted from Z to Y0 or Y1, or from Y0 or Y1 to Z. Its low ON resistance (0.5 ï)

and flatness (0.13 ï) ensures minimal attenuation and distortion of transmitted signals.
