NX3L1T3157GW,125 (NXP)

The NX3L1T3157GW is a low-ohmic single-pole double-throw (SPDT) 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 (Y0 and Y1) 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 1.8V logic levels in 3.3V applications without significant increase in supply current ICC. This makes it possible for the NX3L1T3157 to switch 4.3V signals with a 1.8V digital controller, eliminating the need for logic level translation. It allows signals with amplitude up to VCC to be transmitted from Z to Y0 or Y1 or from Y0 or Y1 to Z. Its low on-resistance (0.5R) and flatness (0.13R) ensures minimal attenuation and distortion of transmitted signals.
