XS3A1T5157

Low-ohmic single-pole double-throw analog switch

Rev. 1 — 17 March 2020

Product data sheet

1. General description

The XS3A1T5157 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 (Y1 and Y2) 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 I_CC. This makes it possible for the

XS3A1T5157 to switch 4.3 V signals with a 1.8 V digital controller, eliminating the need for logic

level translation. The XS3A1T5157 allows signals with amplitude up to V_CCto be transmitted from

Z to Y1 or Y2, or from Y1 or Y2 to Z. Its low ON resistance (0.5 Ω) and flatness (0.13 Ω) ensures

minimal attenuation and distortion of transmitted signals.
