Overview
The NLAS4051DTR2G, produced by onsemi, is an advanced analog multiplexer/demultiplexer IC. It is an improved version of the MC14051 and MC74HC4051, fabricated in sub-micron Silicon Gate CMOS technology. This device offers lower RDS(on) resistance and improved linearity, making it suitable for a wide range of applications. It can operate with either a single supply (2.5-5.0 V) or dual supply (±3.0 V), allowing it to pass signals up to 6.0 VPP without the need for coupling capacitors.
