1. General description

The XS3A4053 is a triple low-ohmic single-pole double-throw analog switch, suitable for use as

an analog or digital multiplexer/demultiplexer. Each switch has a digital select input (nS), two

independent inputs/outputs (nY0 and nY1) and a common input/output (nZ). All three switches

share an enable input (E). A digital enable pin E is common to all 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

XS3A4053 to switch 4.3 V signals with a 1.8 V digital controller, eliminating the need for logic level

translation. The XS3A4053 allows signals with amplitude up to VCC to be transmitted from nZ to

nY0 or nY1; or from nY0 or nY1 to nZ. Its low ON resistance (0.5 Ω) and flatness (0.13 Ω) ensures

minimal attenuation and distortion of transmitted signals.
