CD4053BM

Analog Switches, Multiplexers, Demultiplexers Overview

The CD4053BM is a triple analog switch manufactured by Texas Instruments, belonging to the CD4053B CMOS logic series. It integrates three independent single-pole double-throw (SPDT) switches within a single 16-pin SOIC package. The device supports a single power supply voltage range of 3V to 20V or dual supplies of ±2.5V to ±9V. Key electrical specifications include a maximum on-resistance of 240 ohms and a channel-to-channel matching of 5 ohms. It features a -3dB bandwidth of 30MHz and operates across an extended temperature range from -55°C to 125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer marking and date code against official Texas Instruments documentation to ensure authenticity. Confirm that the component matches the specific CD4053BM part number and package type. Check for any relevant compliance certifications such as RoHS status if required for your application. Ensure storage conditions meet moisture sensitivity level requirements before assembly.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when multiple independent analog signal paths require switching within a compact surface-mount footprint. Consider the 240-ohm on-resistance limit for signal integrity requirements at your operating frequency. Verify that the 3V to 20V supply range aligns with your system power architecture. Compare performance metrics against newer alternatives if higher bandwidth or lower resistance is needed.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component is part of the broader CD405x family of CMOS analog switches, which includes variants like the CD4051 and CD4052. These devices share similar logical structures but differ in channel count and configuration. The CD4053BM specifically offers three SPDT channels, distinguishing it from other members of the series that may provide different multiplexing capabilities.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The CD4053BMT is listed as a discontinued alternative. Other potential substitutes include the CD4053BM96 and CD4053BNSR, which offer similar functionality in different packaging options. Verify pin compatibility and electrical specifications before substituting.
