MC14051BDG

Analog Switches, Multiplexers, Demultiplexers Overview

The MC14051BDG is a digitally controlled analog multiplexer/demultiplexer from the MC14051B series, manufactured by onsemi. It implements an SP8T solid-state switch within a 16-pin SOIC package. The device operates with a supply voltage range of 3.0 Vdc to 18.0 Vdc and supports an analog voltage range of 3.0 V to 18 V. Key electrical parameters include a maximum ON resistance (Ron) of 1050 Ω at 5.0 V supply and 280 Ω at 15.0 V supply. The quiescent current per package ranges from 5.0 nA to 150 nA depending on temperature. The component features a bandwidth of 17 MHz and operates across an ambient temperature range of -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix 'DG' corresponds to the SOIC-16 package configuration as defined in the manufacturer's documentation. Confirm that the procurement source provides valid traceability for the Pb-Free and RoHS compliant status required for regulatory adherence. Ensure the specific lot codes match the assembly location and wafer lot information indicated in the marking diagram to guarantee component authenticity and manufacturing consistency.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single 8-channel analog switch is required within the standard CMOS logic family. Consider alternative devices such as the HC4051 if lower ON resistance or higher speed is necessary for the application. Verify that the control logic levels align with the VDD and VSS supply voltages provided in the system design. Ensure the analog signal swing remains within the VDD to VEE limits to prevent excessive current draw.
