CD4052BE 概述
An analog multiplexer is an analog switch that connects one of several inputs to a common output according to digital control signals. In the CD4052BE, two multiplexer channels operate in parallel, providing simultaneous routing for paired signals. This makes it useful for differential measurements, stereo or balanced signal paths, and systems that need to select two related inputs without using two separate multiplexer packages. Its logic-level conversion feature allows the address inputs to be driven from a supply range different from the analog signal and main supply conditions supported by the device family.
Key features include a dual 4:1 configuration, low typical on-resistance, low off leakage current, binary address decoding, and operation across a 20 V maximum supply. The manufacturer describes the CD4052B as supporting wide digital and analog signal levels, with digital operation identified from 3 V to 20 V in the supplied technical summaries. The 16-pin PDIP package supports through-hole PCB assembly and is identified by distributor listings as a 16-PDIP part.
The device is designed for analog signal multiplexing rather than high-speed digital switching. Its performance depends on supply voltage, signal amplitude, control timing, and the impedance of the connected circuit. The multiplexed path introduces on-resistance and capacitance, while off-channel leakage can influence high-impedance measurements. Engineers should therefore account for source and load impedance, settling time, control-logic levels, and analog signal range when selecting the device.
Typical applications include routing sensor outputs into an analog-to-digital converter, selecting audio or measurement channels, multiplexing instrumentation inputs, and sharing amplifiers or converters across several sources. It is also suitable for educational and prototype boards where a through-hole dual analog multiplexer simplifies wiring.
For reliable layouts, keep the analog signal traces short, connect the supply decoupling capacitor close to the device, route address inputs away from sensitive analog paths, and verify that unused channel and control pins are connected according to the manufacturer datasheet. Do not treat the nominal 4:1 topology as a substitute for checking voltage, current, leakage, and timing limits for the specific signal.

典型应用
CD4052BE 适用于 7 应用s: Analog Sensor Input Multiplexing, ADC Channel Selection, Audio Signal Routing, Instrumentation and Measurement Switching, Control Signal Distribution, Educational and Prototype Circuit Selection, Dual Differential Signal Routing.
Analog Sensor Input Multiplexing
The CD4052BE fits low-frequency sensor aggregation when two related analog signals must be selected from four inputs. Its dual 4:1 architecture allows paired channels to follow the same binary address selection, while the 240 ohm typical on-resistance should be included in the source-impedance budget for the selected sensor. The 20 V maximum supply is suitable for laboratory and industrial signal conditioning above low-voltage logic rails. Place the sensor outputs near the mux pins, keep the analog traces short, and verify the downstream amplifier or converter input range before committing to this use.
推荐
ADC Channel Selection
CD4052BE can route two multiplexed inputs into a shared analog-to-digital conversion path, reducing the number of separate analog front-end channels. The useful benefit is the parallel dual-channel arrangement: two outputs can be selected with the same address state for measurements that require synchronized or paired sampling. Designers must account for the 240 ohm typical on-resistance, the unprovided leakage and switching-time limits, and the ADC acquisition window. Use a downstream buffer when the source impedance or sampling capacitor requirements make the mux resistance significant.
推荐
Audio Signal Routing
The CD4052BE can select among four low-frequency audio or control-signal inputs, and its dual channels can route paired left/right or differential signal paths. The 240 ohm typical on-resistance may be acceptable for many low-impedance audio boards, but it can interact with source impedance and downstream amplifier loading. The device is not presented in the supplied data as a high-performance audio switch, so designers should verify bandwidth, distortion, off leakage, and signal-level limits in the manufacturer documentation. Keep routing traces short and provide stable supply bypassing.
推荐
Instrumentation and Measurement Switching
CD4052BE is appropriate for low-frequency laboratory or industrial measurement systems that need to share an amplifier, meter, or converter across several inputs. The dual 4:1 structure is useful when differential or paired signals must remain associated during selection. Designers should model the switch's 240 ohm typical on-resistance as part of the measurement path and check leakage for high-impedance probes. The 3 V to 20 V digital signal-level range supports several control environments, while the 20 V supply ceiling gives flexibility for analog rails within that limit.
推荐
Control Signal Distribution
The CD4052BE can demultiplex or multiplex low-frequency control signals when a controller needs to share a single interface among several destinations. Its binary address decoding simplifies selection of one of four paths, and the two-channel arrangement can carry complementary or paired commands. The design must ensure that every switched signal remains within the device's absolute maximum ratings, including supply-transient conditions. Use local decoupling and route address lines away from sensitive analog nodes to prevent switching activity from coupling into the selected signal.
推荐
Educational and Prototype Circuit Selection
The CD4052BE is convenient for educational, hobby, and prototype boards because it combines a dual 4:1 analog multiplexer with a through-hole 16-pin PDIP package. Students can use the address inputs to demonstrate selection of four sensor, audio, or measurement channels and observe the effect of the 240 ohm typical on-resistance. For prototype use, verify the common-terminal and address wiring against the datasheet rather than relying on package position alone. A buffered output or resistive divider may be needed when the external circuit has high impedance.
推荐
Dual Differential Signal Routing
The CD4052BE can route two paired analog signals together, which is useful for differential measurements or paired audio channels that must experience the same selection address. This synchronized dual-channel behavior is a practical advantage over a single-channel mux when the downstream circuit treats the two signals as a pair. However, matching and crosstalk performance depend on the external circuit, signal source impedance, and grounding because complete matching and isolation figures are not provided in the verified data. Use symmetrical routing and verify common-mode and absolute maximum limits.

设计说明
Include the verified 240 ohm typical on-resistance in the source-impedance calculation for the selected channel. This matters most when driving a high-impedance sensor, ADC input, or measurement node because the switch resistance combines with the source and downstream input impedance. The supplied search summary also reports 125 ohm typical at 15 V peak-to-peak, but because test conditions are not provided, do not substitute that value without checking the manufacturer datasheet.
Place the supply bypass capacitor close to the device power and ground pins, and route the analog signal paths as short and direct as practical. Keep address traces away from high-impedance analog nodes to reduce coupling from switching edges. The CD4052BE is a 16-pin PDIP, so through-hole lead spacing and pin numbering must be checked against the actual package drawing before layout release.
Do not infer pin functions from the CD4000-series name alone. The supplied data identifies a dual 4:1 configuration but does not include a complete CD4052BE pin table, so verify common terminals, address inputs, supply pins, and unused pins in the manufacturer datasheet. Also confirm that all analog and logic voltages remain within the absolute maximum limits, particularly during power sequencing and transients.
The verified maximum supply is 20 V, while the reported digital signal-level range is 3 V to 20 V. These are not blanket permission to place any signal or control voltage on every pin. Establish the supply and signal rails independently, ensure address logic levels are valid for the selected operating condition, and use a defined shutdown sequence if the external circuit can leave the control inputs floating.
合规信息
The supplied search results identify the manufacturer, package, topology, voltage range, and on-resistance, but do not provide verified RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements.
