MC14053BDR2G is listed in the Analog Switches, Multiplexers, Demultiplexers range at ChipApex. The manufacturer field lists Fairchild Semiconductor. Its product description is SINGLE-ENDED MULTIPLEXER, 3 FUNC. Review the specifications below when checking this part for your BOM.
The MC14053BDR2G is a triple single-pole double-throw (SPDT) analog multiplexer manufactured by onsemi, formerly Fairchild Semiconductor. It operates within a supply voltage range of 3 V to 18 V and features low ON impedance and very low OFF leakage current. The device provides break-before-make switching action and includes triple diode protection on control inputs. Packaged in a 16-SOIC surface-mount format, it supports analog signal ranges up to the complete supply voltage span.
Verify the manufacturer designation carefully, as the component was originally developed by Fairchild Semiconductor but is now produced by onsemi following corporate restructuring. Confirm that the specific ordering suffix matches the required package type and environmental compliance standards for your assembly process.
Select this component when a triple SPDT analog switch with low ON resistance is required. Ensure the operating voltage falls between 3 V and 18 V. Consider HC-series variants if lower ON resistance or higher speed is needed, as they offer improved performance metrics while maintaining pin compatibility.
This part belongs to the MC1405xB family of analog multiplexers, which also includes the MC14051B (8:1) and MC14052B (4:1 dual). These devices share similar electrical characteristics and packaging options, allowing for flexible design choices based on channel count requirements within the same logic family.
Public documentation confirms pin-for-pin replacement compatibility with the CD4053. Designers may also consider HC4053 variants for applications requiring lower ON resistance or faster switching speeds, provided voltage levels remain within specified limits.
