CD4067BE - 20V 16:1 Analog Multiplexer | Texas Instruments
MPN: CD4067BE ✗ Cuối đờiCD4067BE Tóm tắt
An analog multiplexer is a digitally controlled routing component that connects one common signal to one selected member of a larger signal group. A 16:1 multiplexer provides sixteen input choices through four binary select lines, reducing wiring and conserving converter inputs. CMOS implementations are useful where low static power, wide supply-voltage operation, and bidirectional signal paths are desired. The CD4067BE can also be used as a demultiplexer by exchanging the signal-flow orientation described in the manufacturer documentation, although its primary function is analog multiplexing.
The key verified features are 16:1 channel selection, four-level digital addressing, a 240 ohm maximum on resistance, a 20 V maximum supply rating, and operation from 3 V to 18 V according to the available technical sources. The selected channel is controlled by A, B, C, and D address inputs, while the inhibit/strobe function provides channel disabling. Because the on resistance contributes to signal loss and thermal behavior, the source impedance and downstream input impedance should be evaluated together in precision measurement circuits.
The internal address decoder reduces the external control logic required to select one of 16 channels. The device is therefore suitable for systems in which a microcontroller or other digital controller must scan resistive, capacitive, voltage, or current-derived analog inputs. Its 24-pin PDIP package is intended for through-hole PCB assembly, while the CD4067B family provides the functional platform and the manufacturer product page supplies the authoritative family information.
Typical uses include multiplexed sensor interfaces, automated test equipment, industrial control panels, data-acquisition systems, and analog signal routing between shared measurement circuitry and multiple external sources. When using the CD4067BE, verify signal amplitudes against the supply rails, account for on-resistance error, provide adequate input and output drive paths, and keep sensitive routing away from high-impedance nodes. The verify data does not provide complete timing, leakage, temperature, or absolute-maximum tables, so those values should be confirmed in the manufacturer datasheet before production release.

Ứng dụng tiêu biểu
CD4067BE phù hợp cho 6 Áp dụngs: Multiplexed Sensor Input, Data Acquisition System, Automated Test Equipment, Industrial Control Panel, Analog Signal Routing, Programmable Calibration Network.
Multiplexed Sensor Input
The CD4067BE is suitable for scanning up to 16 analog sensor outputs with one shared acquisition or amplifier channel. Four binary address inputs select the active route, while the inhibit input can disable the switch during transitions. Because the verified on-state resistance reaches 240 ohm, use low source impedance and appropriately buffered inputs to limit divider error. A resistive divider, temperature sensor, or pressure sensor can therefore share a compact analog front end, provided its signal remains within the device’s verified supply range and the receiving circuit’s input limits.

Data Acquisition System
Use the CD4067BE to reduce the number of analog inputs required by an ADC or instrumentation amplifier. The controller presents a four-bit channel code, waits for the selected path to settle, and then samples the common node. The 16:1 architecture is valuable in compact test and measurement equipment where 16 inputs would otherwise require many external switches. The 240 ohm maximum on resistance should be included in the acquisition error budget, and source and destination impedances should remain controlled for accurate readings.
Được đề xuất
Automated Test Equipment
The CD4067BE can route test stimuli or measured responses across as many as 16 external lines in automated test equipment. A microcontroller can scan channels systematically, isolate inactive paths with the inhibit function, and capture results through a shared instrument. The through-hole 24-pin PDIP package is convenient for leaded assemblies and prototype fixtures. Keep analog traces short, use a common ground reference, and validate that test-signal amplitudes remain compatible with the CD4067B electrical limits before applying power.
Được đề xuất
Industrial Control Panel
In an industrial control panel, the CD4067BE can monitor multiple analog command or feedback signals while the controller uses one shared input. This simplifies wiring compared with sixteen dedicated analog channels and makes channel diagnostics easier to implement. The four address lines and inhibit line provide straightforward digital control from a microcontroller or logic sequencer. Because industrial signals may be noisy or slow-changing, add appropriate filtering, clamping, isolation, and grounding rather than relying on the mux alone for protection.
Được đề xuất
Analog Signal Routing
The CD4067BE can route one analog source to one of 16 destinations, or reverse the signal orientation for demultiplexing, when the circuit design and signal levels support that use. This is useful for programmable gain, calibration, or signal-distribution systems where a controller selects one path at a time. The verified 240 ohm maximum on resistance means long or high-impedance routes should be modeled carefully. Keep the selected channel stable during conversion and use the inhibit function to prevent unintended paths during address changes.
Được đề xuất
Programmable Calibration Network
A calibration system can use the CD4067BE to select among multiple reference or correction signals applied to a shared measurement chain. The address controller can step through known sources, record deviations, and store compensation values in the host controller. Because the mux contributes up to 240 ohm of path resistance, calibration should be performed with the same source and load conditions used in operation. The device’s 3 V to 18 V supply range supports integration with many legacy CMOS measurement designs.

Bảo phân biệt quan trọng
- 16:1 single-ended analog channel selection (vsCD4097BE)

- Verified maximum on resistance of 240 ohm (vsCD4097BE)
- 20 V family rating (vsCD4097BE)
Ghi chú thiết kế
The verified maximum on-state resistance is 240 ohm, so treat the mux as part of the signal-path impedance. For a source resistance Rs and receiving input resistance RL, the inserted resistance can create a voltage-divider error. Use low-impedance drive and buffering where accuracy matters, and include the actual on resistance, connector resistance, and input impedance in the system error budget.
Keep the common node, channel traces, and control inputs physically distinct on the board. Route analog channel paths away from digital clock and switching-node traces, use a continuous ground reference, and place any input filtering close to the protected signal source. Because the verified data does not provide complete switching-time or leakage values, validate settling time and crosstalk on the finished layout rather than relying on nominal channel selection alone.
Do not substitute CD4097BE for CD4067BE on the assumption that both use 24-pin PDIP packages. CD4067BE is a 16-channel single-ended mux, while CD4097 is identified in the verified comparison data as an eight-channel differential mux. Also verify the CD4067B pinout, logic levels, signal-range limits, and inhibit polarity from the official TI datasheet before connecting external circuitry.
