CD4053BCN

Analog Switches, Multiplexers, Demultiplexers Overview

The CD4053BCN is a triple 2-channel analog multiplexer/demultiplexer manufactured by onsemi in a 16-lead Plastic Dual-In-Line (PDIP) package. It features three independent single-pole double-throw (SPDT) switches controlled by binary inputs A, B, and C, plus an inhibit input. The device operates with a DC supply voltage range of +5V to +15V and supports analog signal amplitudes up to 15V peak-to-peak. Key electrical characteristics include a typical 'ON' resistance of 80Ω at VDD-VEE=15V, channel leakage current of ±10pA, and a bandwidth of 40MHz. It functions within an operating temperature range of -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel availability. Confirm RoHS compliance status as specifications may vary by production lot or region. Ensure the component source matches the authorized distributor list to avoid counterfeit parts. Check for any process change notifications that might affect pin compatibility or electrical parameters before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a design requires three independent analog switches in a single DIP package. Verify that the required analog signal swing does not exceed the 15V peak-to-peak limit defined in the datasheet. Ensure the control logic voltage levels are compatible with the specified VDD range. Consider the thermal dissipation capabilities of the PDIP package if multiple channels are active simultaneously under heavy load conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

The CD4053BC belongs to the CD405x family of CMOS analog switches, which also includes the CD4051 (8-channel) and CD4052 (dual 4-channel). This family is designed for general-purpose analog signal switching applications requiring low power consumption and wide dynamic range. The BC variant typically denotes standard commercial/industrial grade performance specifications compared to military or extended variants.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the CD4053B from other manufacturers such as Texas Instruments. Verify that the replacement part maintains the same 16-pin DIP footprint and electrical characteristics, particularly the 'ON' resistance and leakage current specs. Cross-reference the absolute maximum ratings to ensure the substitute can handle the same supply voltages and signal swings.
