MC14053BDG

Analog Switches, Multiplexers, Demultiplexers Overview

The MC14053BDG is a Triple SPDT Analog Multiplexer/Demultiplexer manufactured by onsemi. It operates within a supply voltage range of 3.0 Vdc to 18 Vdc and supports an analog voltage range of 3.0 to 18 V. The device features low ON impedance, with typical values of 250 Ω at 5 V, 120 Ω at 10 V, and 80 Ω at 15 V. Off-channel leakage current is typically ±0.05 nA at 15 V. Propagation delay times are specified as 65 ns at 5 V, 20 ns at 10 V, and 15 ns at 15 V. The bandwidth is 17 MHz. It is housed in a SOIC-16 package and functions as a digitally controlled analog switch.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix 'DG' confirms the SOIC-16 surface-mount package and lead-free status. Confirm the manufacturer is onsemi. Check RoHS compliance documentation. Ensure the specific revision matches design requirements. Validate pinout compatibility if replacing legacy components.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when three independent SPDT analog switches are required in a single package. Verify that the supply voltage range of 3V to 18V meets system requirements. Consider the ON resistance characteristics relative to the load current. Ensure the operating temperature range of -55°C to +125°C fits the application environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MC14053B is part of the MC1405xB family of analog multiplexers from onsemi, which also includes the MC14051B (8-channel) and MC14052B (dual 4-channel). These devices share similar electrical characteristics and pinout structures, allowing for flexible design choices based on channel count requirements while maintaining compatibility with standard CMOS logic levels.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet specifies pin-for-pin replacement for CD4053. Designers may consider HC4053 variants for lower ON resistance applications. Verify package dimensions and pin assignments when substituting.
