1. General description

The XS3A4052 is a low-ohmic dual-pole quad-throw analog switch (DP4T), suitable for use as an

analog or digital multiplexer/demultiplexer. Each switch features four independent inputs/outputs

(nY0, nY1, nY2 and nY3) and a common input/output (nZ). A digital enable input (E) and two digital

select inputs (S0 and S1) are common to both switches. When E is HIGH, the switches are 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

XS3A4052 to switch 4.3 V signals with a 1.8 V digital controller, eliminating the need for logic

level translation. The XS3A4052 allows signals with amplitude up to VCC to be transmitted from

nZ to nYn or from nYn to nZ. Its low ON resistance (0.5 Ω) and flatness (0.13 Ω) ensures minimal

attenuation and distortion of transmitted signals.
