CD4067BM 概要
An analog multiplexer is a switching component that connects one common signal path to one selected member of a larger channel group. A demultiplexer uses the same internal switch network in the opposite signal direction, routing a common input to a selected output. The CD4067B belongs to the CMOS analog-switch family within logic and interface integrated circuits. Its internal address decoder converts four binary select inputs into one of 16 channel states, simplifying control from a microcontroller or digital logic system.
Key verified characteristics include a 20 V maximum supply-oriented device rating, 16:1 multiplexing, one analog circuit, and 240 ohms on-resistance as listed by DigiKey. The manufacturer describes low on impedance, low off leakage current, and relatively constant on-resistance over the selected signal range. The four address inputs and inhibit control provide deterministic channel selection, while the common and channel terminals carry the analog signal. Exact voltage, leakage, timing, and temperature limits beyond the supplied verified data are not asserted here.
Because the CD4067BM is a CMOS analog switching device, its performance depends on supply voltage, control-signal levels, signal amplitude, leakage, channel resistance, and the impedance presented by the selected source or destination. The common terminal and channel terminals should be treated as analog nodes rather than ordinary digital outputs. Designers should account for off leakage and on-resistance when measuring high-impedance sources, and should ensure that control states remain valid during power transitions.
Typical uses include sensor selection, instrumentation signal routing, test-equipment channel selection, data-acquisition systems, and industrial control interfaces. For a sensor front end, the four select lines can choose one of 16 inputs while the inhibit function provides an effective disconnected state. The same topology can be used in reverse when a source must be routed to one of multiple outputs. The analog bandwidth and switching-time limits should be checked against the signal path requirements.
A practical design consideration is to keep the selected channel traces short and place suitable bypassing close to the supply pins. The mux should be selected according to source impedance and measurement accuracy: high-impedance sensors may be more sensitive to leakage, while low-impedance drive paths emphasize on-resistance and switching behavior. This page combines verified manufacturer and distributor information, structured application guidance, and source-linked design cautions rather than extrapolating unprovided electrical limits.

主な用途
CD4067BM の用途: 6 件s: Multichannel Sensor Acquisition, Industrial Control Signal Routing, Test and Measurement Signal Selection, Audio and Analog Signal Distribution, Data Acquisition Front Ends, Embedded Measurement and Monitoring.
Multichannel Sensor Acquisition
The CD4067BM is suitable for selecting one of 16 analog sensor inputs in a data-acquisition or monitoring system. Four binary address lines and internal decoding reduce the control burden on a microcontroller, while the common terminal connects to the selected external channel. The verified 240-ohm on-resistance should be included in the source-impedance error analysis, especially for resistive dividers or thermistors. For high-impedance sensors, verify the manufacturer leakage and settling specifications before selecting this mux, and place the selected traces away from switching and digital-clock nodes.
おすすめ
Industrial Control Signal Routing
The 16-channel architecture makes CD4067BM useful for routing multiple analog control or feedback nodes through a common analog path. The four address inputs can be driven by a controller, and the inhibit function can provide a controlled inactive state when the system requires isolation of the selected path. Because the device is specified as a CMOS analog multiplexer with low off leakage and relatively constant on-resistance, the design should still verify signal amplitude and load current against the manufacturer data. PCB layout should minimize trace length and maintain a stable return path.
おすすめ
Test and Measurement Signal Selection
CD4067BM can reduce the number of external connections in a test fixture by selecting one of 16 measurement paths to a common instrument or converter input. The verified 16:1 configuration and 240-ohm on-resistance make source impedance and channel attenuation important design variables. Use short, shielded routing where appropriate, and verify that the selected source is stable during switching. The device is not a precision resistor network by itself; measurement accuracy still depends on the source impedance, leakage, settling time, and the characteristics of the downstream instrument.
おすすめ
Audio and Analog Signal Distribution
The CD4067BM can route one analog source among multiple destinations when used in a demultiplexer arrangement, provided signal amplitude and loading are compatible with the switch. This can support controlled analog distribution in test boards or instrumentation rather than high-fidelity audio power routing. The verified 240-ohm on-resistance is a meaningful insertion-loss element for low-impedance loads, so the receiving circuit should be checked for loading. Route the common and channel lines as controlled analog nets and isolate them from digital switching paths where possible.
おすすめ
Data Acquisition Front Ends
A 16:1 analog multiplexer is useful when a system has more analog inputs than the downstream converter can accept. CD4067BM allows a controller to select a sensor or conditioned signal path and route it to a shared ADC input. The design should verify the mux on-resistance, leakage, bandwidth, and settling behavior against the converter acquisition time; those values are not fully present in the supplied search excerpts. The internal address decoder simplifies firmware, but the control signals must remain stable and electrically valid during the conversion sequence.
おすすめ
Embedded Measurement and Monitoring
CD4067BM can consolidate multiple analog inputs in an embedded monitoring system, allowing a microcontroller-driven board to inspect temperature, voltage, or condition signals one channel at a time. The compact 24-pin SOIC package supports surface-mount PCB construction, while the 16-channel selection reduces the need for many separate analog input lines. For low-energy embedded designs, verify quiescent behavior and supply-current figures from the TI datasheet because those specifications are not included in the supplied excerpts. Use stable reference and sensor excitation circuits to avoid confusing mux errors with source errors.

主な差別化要因

- Simplified control using four binary select inputs （vs CD4067BM96)
設計ノート
Treat the common and channel terminals as analog signal paths rather than digital outputs. The verified 240-ohm on-resistance should be included in the source/load impedance budget, especially when the selected channel drives a high-gain amplifier or precision converter. Keep traces short, provide a continuous return plane, and avoid routing selected channels beneath digital clocks or switching regulators. Confirm leakage, bandwidth, and settling behavior from the TI CD4067B datasheet before assigning an allowable measurement error.
Place the device so that analog channel traces can be routed directly to their source or destination networks, while keeping the four address lines and inhibit connection away from sensitive analog paths. Provide local supply bypassing at the device according to the manufacturer recommendations and maintain a low-impedance ground reference. The exact pin names and layout guidance must be taken from the official datasheet pinout; the supplied verification does not include the full pin table, so this record leaves pinout null.
Do not select a substitute solely because another part also has 16 channels and a 24-pin SOIC package. Verify supply range, control thresholds, on-resistance, off leakage, bandwidth, timing, temperature range, and absolute maximum ratings for the exact ordering code. Also confirm that the control system does not expect 3.3 V or 5 V logic thresholds when the candidate operates from a different supply rail. Use the TI datasheet and the candidate manufacturer's datasheet for an apples-to-apples comparison.
コンプライアンス情報
The supplied verified snippets do not provide explicit RoHS, REACH, lead-free, halogen-free, or conflict-minerals statements. The device is an analog multiplexer rather than an automotive-qualified power component, so AEC-Q100 is marked not_applicable only as a category classification; no automotive qualification is claimed.
