MC14053BD

Analog Switches, Multiplexers, Demultiplexers Overview

The MC14053BD is a triple 2-channel analog multiplexer/demultiplexer manufactured by onsemi in a 16-pin SOIC package. It operates within a supply voltage range of 3.0 Vdc to 18.0 Vdc and supports an analog signal range of 3.0 V to 18 V. The device features low ON resistance, with maximum values ranging from 220 Ω at 15 V to 800 Ω at 5 V. Propagation delay times are typically 9.0 ns to 26.5 ns depending on load capacitance. The bandwidth is specified at 17 MHz, and the operating temperature range extends from -55 °C to +125 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'D' corresponds to the SOIC-16 package variant required for your PCB layout. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the ordering code matches the exact pinout and thermal characteristics needed for your enclosure design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a compact solution for three independent analog switches is required. The wide supply voltage range accommodates both single and dual power rails. Verify that the maximum ON resistance meets your signal integrity requirements for the specific voltage levels used in the application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MC1405xB family of analog multiplexers, which also includes the MC14051B (8-channel) and MC14052B (dual 4-channel). All devices share similar electrical characteristics and pinout compatibility within the 16-pin form factor, allowing for flexible system architecture choices based on channel count needs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet identifies the CD4053 as a pin-for-pin replacement. HC-series variants such as the HC4053 offer lower ON resistance but may require different drive considerations due to speed differences.
