XS3A1T3157 Low-ohmic single-pole double-throw analog switch Rev. 1 17 March 2020 Product data sheet 1. General description The XS3A1T3157 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 . This makes it possible for the CC XS3A1T3157 to switch 4.3 V signals with a 1.8 V digital controller, eliminating the need for logic level translation. The XS3A1T3157 allows signals with amplitude up to V to be transmitted from CC Z to Y1 or Y2, or from Y1 or Y2 to Z. It s low ON resistance (0.5 ) and flatness (0.13 ) ensures minimal attenuation and distortion of transmitted signals. 2.
