CD4052BM 개요
An analog multiplexer is a switching IC that routes one selected input channel to an output, or distributes one output signal among selectable inputs. In a demultiplexer arrangement, the same primitive can connect one source to one of several destinations. The CD4052BM uses A and B select inputs together with an inhibit input to control the selected channel, while logic-level conversion helps bridge different supply domains.
The key verified feature set includes a 20 V maximum supply rating, dual four-channel analog multiplexing, logic-level conversion, 240 ohm on-resistance, and a 16-SOIC package. These characteristics make the device useful for analog signal routing, test and measurement systems, data acquisition, control systems, and embedded signal-conditioning boards. The multiplexer's purpose is not signal amplification; external buffers, protection, or signal conditioning may still be required.
The CMOS architecture is suited to low-power control and analog routing systems, but the exact switching speed, leakage current, channel capacitance, input voltage limits, and operating temperature range were not included in the supplied verified data. Those values should be checked in the manufacturer datasheet before final design release, especially when switching high-frequency, high-impedance, or precision signals. The listed 240 ohm on-resistance is a distributor description and should not be treated as a substitute for the complete datasheet electrical tables.
Typical implementation places the A, B, and inhibit controls on digital I/O lines and routes sensor, measurement, or communication signals through the selected differential pair. If the source or destination is outside the mux's supported voltage range, protection and level shifting must be added. For battery-powered equipment, verify leakage and quiescent-current behavior, since those specifications are not present in the verified excerpt.
A key design consideration is control-state timing during power-up. Select inputs should be held in a defined state before analog signals become active to prevent unintended channel connection. PCB routing should keep mux traces short, provide a solid ground reference, and place any external input and output protection close to the pins.
This page combines the verified Texas Instruments product description, distributor specifications, package data, sourcing links, and engineering guidance. It also distinguishes documented values from parameters that require confirmation in the manufacturer datasheet, helping engineers evaluate CD4052BM procurement and design-fit requirements without inventing missing specifications.

일반적인 애플리케이션
CD4052BM 적합 용도: 6 애플리케이션s: Multichannel Sensor Acquisition, Data Acquisition Front Ends, Test and Measurement Routing, Analog Signal Multiplexing, Industrial Control Signal Routing, Communication and Interface Routing.
Multichannel Sensor Acquisition
CD4052BM fits sensor-conditioning boards that must connect several analog sources to one shared amplifier or converter. Its verified 4:1, two-channel architecture selects one differential input pair while preserving a paired output, reducing the number of external signal paths. The 20 V maximum supply condition can suit higher-voltage industrial sensor systems, but the exact input range, leakage, and bandwidth must be confirmed in the TI datasheet before selecting resistor values or amplifier topology.
추천
Data Acquisition Front Ends
A CD4052BM can scan multiple analog inputs into a shared measurement chain when board area and connector count are constrained. The 4:1 configuration provides channel selection using control logic, while the two-channel arrangement supports paired or complementary signals. Use short PCB traces and a stable reference return to minimize errors. The verified 240 ohm on-resistance figure is a useful initial design consideration, but settling behavior and charge injection are not supplied and must be measured or obtained from the manufacturer documentation.
추천
Test and Measurement Routing
Instrumentation boards can use CD4052BM to route selected test signals to a common measurement amplifier, relay driver, or display-processing channel. The device's two-channel 4:1 structure is useful when a system needs paired routing rather than a single-ended selector. Keep the control traces away from sensitive analog nodes and provide defined logic states during reset. Before using it for high-frequency or precision measurements, verify switching time, off leakage, channel capacitance, and on-resistance variation from the official TI datasheet.
추천
Analog Signal Multiplexing
CD4052BM is suitable for general analog routing where one of several differential sources must reach a downstream circuit. The logic-level-conversion feature can simplify interfacing between the mux and a host with a different control voltage, although the exact thresholds must be checked. Keep analog and return paths together, provide local bypassing near the device, and avoid using the mux as a precision buffer. Its verified 240 ohm on-resistance should be included in source-load and gain-error calculations.
추천
Industrial Control Signal Routing
Industrial control boards can use CD4052BM to select command, feedback, or diagnostic signals while sharing a common controller input. The 20 V maximum supply condition is relevant for higher-voltage control environments, but every analog terminal must remain within the datasheet limits. Add input clamping where transients or inductive coupling are possible, and ensure the inhibit and select states have defined pull resistors. The verified data does not specify surge withstand or automotive qualification, so those requirements must be validated separately.
추천
Communication and Interface Routing
The CD4052BM can route compatible low-speed analog or logic-level interface signals in embedded systems that need selectable source paths. Its 4:1 selection and inhibit control provide flexible channel management, while the logic-level-conversion function may reduce control-interface complexity. Do not assume the device is suitable for high-speed USB, Ethernet, or RF signals; the supplied data does not verify bandwidth, propagation delay, or isolation. Use it for low-to-moderate-speed routing and confirm timing in the manufacturer datasheet.

설계 노트
Keep the analog signal traces and their return paths short and closely referenced to ground. Place any protection components near the connector or signal source, and avoid routing the mux control lines directly beneath sensitive analog traces. The supplied data confirms a 16-pin SOIC package but does not provide a land pattern; use the package drawing in the manufacturer datasheet and verify the PCB footprint before fabrication.
Do not assume that the 20 V maximum supply value is the permitted analog signal range. Confirm input and output limits, control thresholds, and the power-supply operating range in the TI datasheet. During reset and power sequencing, hold A, B, and inhibit in defined states so the mux does not connect an unknown or transient signal to the selected output.
Use the verified 240 ohm on-resistance as an initial loss estimate, but do not finalize precision signal-chain budgets without the datasheet test conditions and frequency-dependent data. For high-impedance sources, leakage and input capacitance can dominate the error; for fast signals, control timing and propagation delay matter. Add an external buffer when the source impedance is high or the required settling time is short.
Place local supply decoupling close to the device pins and verify the required capacitor type and value from the manufacturer datasheet. The supplied excerpt does not provide quiescent current, supply-current limits, or decoupling recommendations, so those values must not be assumed. Check the analog and logic supplies for sequencing conflicts, especially when the select logic and analog source use different rails.
규정 준수 정보
The supplied verified data does not include RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements for CD4052BM. AEC-Q100 is recorded as not_applicable only because no automotive qualification is identified in the supplied material; verify the exact part and manufacturer documentation before production release.
