CD4053BM Übersicht
What is a CMOS analog multiplexer? A CMOS analog multiplexer is a semiconductor switch that connects one common signal terminal to one of multiple channel terminals according to digital control logic. The CD4053BM is a triple SPDT device: each of its three switches has a common terminal and two selectable terminals, and the inhibit function provides shared control. In the signal-chain hierarchy, it is an analog switch, then a multiplexer or demultiplexer, and ultimately a logic IC with analog signal-routing capability.
The verified manufacturer description identifies a 20 V supply, three independent 2:1 channels, and logic-level conversion. The CD4053BM can therefore support both analog multiplexing and demultiplexing functions, including source selection, signal routing, and shared test or measurement paths. The 240 ohm on-resistance listed by DigiKey is useful for impedance-sensitive designs because it can introduce signal attenuation and bandwidth limits when driving high-impedance or capacitive loads.
In a typical circuit, the A, B, and C inputs determine which terminal of each SPDT switch connects to its common terminal. The inhibit input provides a common disable mechanism, allowing the circuit to isolate selected paths during test or control sequences. Logic-level conversion is useful when the control signals originate from a supply domain different from the analog signal supply. The device should be selected only when its voltage, current, temperature, and logic thresholds satisfy the actual signal path.
Typical uses include sensor selection, instrumentation, analog signal routing, control systems, test equipment, and embedded measurement modules. Because the on-resistance is nonzero, avoid using the CD4053BM as a low-loss precision switch or for high-speed signals without checking bandwidth, charge injection, and capacitive-load behavior. The manufacturer product page is the authoritative source for ordering information, parameters, and support documents.
A key design consideration is to account for the analog signal amplitude, supply voltage, control logic levels, and load impedance at the common terminals. Keep routing traces short, provide a stable supply reference, and ensure the control signals remain within the device's specified logic thresholds. The 16-SOIC footprint simplifies assembly in conventional through-hole-compatible surface-mount layouts, but the complete pinout and electrical limits must be checked against the official datasheet.
This page combines the verified TI product description, distributor identification of the 16-SOIC package and 240 ohm on-resistance, and practical selection guidance. It does not invent unverified temperature, leakage, bandwidth, pricing, or absolute-maximum values; missing engineering parameters are marked for review in the specifications.

Typische Anwendungen
CD4053BM ist geeignet für 6 Anwendungs: Sensor Signal Multiplexing, Test and Measurement Signal Routing, Embedded Analog Control, Analog Demultiplexing, Instrumentation Signal Conditioning, Programmable Control Interfaces.
Sensor Signal Multiplexing
The CD4053BM fits low-voltage sensor-selection circuits that need to route several measurement sources through a shared analog input. Its three independent 2:1 SPDT channels provide separate routing paths for A, B, and C selections, while the inhibit input can disable the switch network during idle or test states. The verified 240 ohm on-resistance may be acceptable with high-impedance sensors, but it can create measurement error with low-impedance sources. Check leakage, settling behavior, logic thresholds, and signal limits against the TI datasheet before using it for precision measurements.
Empfohlen
Test and Measurement Signal Routing
The CD4053BM is useful in test fixtures and measurement interfaces where several analog nodes must be selected for a shared instrument or comparator. Three SPDT paths can organize separate stimulus, return, or monitor connections, while the inhibit function provides a convenient isolation control. Because the verified on-resistance is 240 ohm, instrument input impedance and probe capacitance should be checked to avoid excessive loading. The device should not replace a precision relay when insertion resistance, leakage, or switching transients dominate the measurement budget.
Empfohlen
Embedded Analog Control
The CD4053BM can select analog control or feedback paths in an embedded controller board when the system needs more routing flexibility than discrete switch contacts provide. The three A, B, and C control inputs map naturally to digital outputs or an I/O expander, while logic-level conversion can simplify control-system interfacing. Keep control traces short and ensure that all selected terminals remain within the device's validated analog voltage range. The 240 ohm path resistance should be included in gain and offset analysis for resistive sensor networks.
Empfohlen
Analog Demultiplexing
The CD4053BM can demultiplex one analog signal into selectable destinations, allowing a controller to distribute a common signal to one of two possible loads per channel. This is useful in modular analog systems, programmable interface boards, and signal-distribution networks. The same 240 ohm on-resistance affects both multiplexed and demultiplexed paths, so destination loading must remain suitable. Verify whether the destination is high impedance and whether the selected signal bandwidth is adequate before relying on the CD4053BM for higher-frequency content.
Empfohlen
Instrumentation Signal Conditioning
The CD4053BM can be placed in front of signal-conditioning circuitry to select among related analog inputs before amplification or conversion. Its three independent channels support compact routing in instrumentation designs, and logic-level conversion helps bridge control and analog domains. The component is most appropriate when modest insertion resistance is acceptable and the signal path is not precision-critical. Designers should account for the 240 ohm on-resistance, control timing, input leakage, and any capacitive loading introduced by long PCB traces or downstream amplifiers.
Empfohlen
Programmable Control Interfaces
The CD4053BM supports programmable routing in control and interface assemblies where software must select between analog states. Separate A, B, and C controls make channel selection straightforward, and the inhibit input provides a common shutdown or isolation path. It is useful in equipment with selectable test modes, configurable signal paths, or multiplexed control lines. Validate logic polarity and timing against the manufacturer datasheet, and avoid using the device where the switched signal itself requires very low resistance, very low leakage, or high-frequency performance not established by the supplied data.

Designhinweise
Account for the verified 240 ohm on-resistance in the complete signal path. For a resistive source, this resistance can create divider action with the source and load and reduce signal amplitude; for a capacitive or high-frequency node, it also increases the effective pole frequency. Estimated rule of thumb: with a 10 pF load, the RC time constant using 240 ohm is 2.4 ns, so layout capacitance and downstream input capacitance must be checked. Use the manufacturer datasheet for frequency-dependent on-resistance and switching data before sign-off.
Do not infer that every CD4053-family label is electrically identical. Confirm the exact ordering suffix, package, temperature range, logic thresholds, analog signal limits, and absolute maximum ratings against the TI datasheet. The verified search data identifies CD4053BM as a 16-SOIC 3-channel device, but it does not provide the complete pin-level electrical table. In particular, verify inhibit polarity and control timing rather than assuming active-high or active-low behavior.
Place the IC close to the analog source, destination, and control-driver circuitry. Keep analog traces short, route control inputs away from sensitive analog nodes where practical, and provide a solid ground reference. If the selected signal is high impedance, minimize leakage paths and guard exposed routing areas. The 16-SOIC footprint must be checked against the official land pattern and pin numbering because a complete verified pin list was not supplied.
Decouple the device supply close to the power and ground pins according to the manufacturer datasheet. Confirm the required supply voltage and input levels for both the analog signal and digital controls. The verified product page describes a 20 V device class, but that does not establish a universal operating limit for every terminal or control condition. Validate power sequencing, control-state defaults, and inhibit behavior during startup and shutdown.
Compliance-Informationen
The supplied search results do not provide verified compliance statements for RoHS, REACH, AEC-Q100, lead-free status, halogen-free status, or conflict-minerals compliance. Verify these attributes from the current TI product documentation or supplier certificates.
