XS3A1T5157

Low-ohmic single-pole double-throw analog switch

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_CC to 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.
