What this dual 4:1 analog multiplexer does in your signal chain
The MPC4D is a dual 4:1 analog multiplexer in a 16-pin SOIC package. It routes one of four input signals per channel to a common output, controlled by a digital address line. This is a standard building block for analog signal routing in data acquisition, test equipment, and industrial control boards where you need to share a single ADC or amplifier across multiple sensor inputs.
The RoHS compliance status is listed as non-compliant, which means this part contains lead and is not suitable for assemblies that must meet RoHS exemption-free requirements. If your BOM mandates RoHS compliance, you will need to look at a lead-free alternate or confirm an exemption applies.
The MPC4D is, not on tape and reel. For automated pick-and-place assembly, you will need to transfer the parts to a feeder-compatible carrier or plan for manual placement. The 16-pin SOIC footprint is a standard JEDEC outline, so board layout is straightforward with any SOIC-16 land pattern.
