CD4052B 概述
An analog multiplexer is a switching IC that connects one of several analog terminals to a common terminal according to binary control logic. In the broader hierarchy, the CD4052B belongs to the CMOS analog-switch and multiplexer class, which sits within interface ICs and broader semiconductor signal-routing systems. Logic-level conversion allows the control inputs to operate from a separate supply domain from the analog signal path, subject to the manufacturer’s absolute-maximum and operating limits.
The verified manufacturer description identifies the CD4052B as a 20 V, 4:1, 2-channel multiplexer with logic-level conversion. The verified distributor listing for CD4052BPWR identifies a 2-circuit, 4:1, 240 ohm, 16-TSSOP variant. The selected CD4052B MPN does not itself specify a package suffix, so package-specific physical details, pin names, pinout, and orderable packaging must be confirmed against the applicable TI datasheet ordering table.
The CD4052B is useful for sensor selection, measurement-signal routing, audio or communications channel selection, and control systems where analog signals must be routed under digital control. Because it is a CMOS analog switch, designers should account for signal amplitude, leakage, on-resistance variation, control timing, supply levels, and the maximum analog voltage when selecting external circuitry. The inhibit input provides a way to isolate a selected path during reset or system states.
The primary design trade-off is that the broad 20 V-capable signal range comes with analog-switch behavior rather than the performance of a modern low-voltage, low-resistance mux. Engineers should verify the exact datasheet limits, package drawing, truth table, and control-input levels before layout or replacement work. The manufacturer product page and datasheet should be treated as authoritative for all unreported values.
This page combines the verified TI product description, distributor package information, cross-reference results, and practical routing guidance. It does not invent electrical values, pricing, pin assignments, compliance claims, or package dimensions that were not supplied in the verified data.

典型应用
CD4052B 适用于 6 应用s: Sensor Signal Multiplexing, Industrial Measurement Systems, Audio Channel Selection, Automotive Signal Routing, Communications Interface Routing, Control-System Signal Isolation.
Sensor Signal Multiplexing
The CD4052B is suitable for selecting among multiple analog sensor outputs when the system must reduce the number of input channels presented to an ADC or measurement controller. Its verified 4:1, 2-channel architecture supports two independent switched paths, while logic-level conversion helps separate control signaling from the analog supply domain. The principal engineering consideration is the resistance and leakage of the selected analog switch, particularly when sensors have high source impedance. The 240 ohm value applies to the verified CD4052BPWR variant and should not be assumed for every CD4052B ordering option. Designers should verify the package pinout, truth table, and operating limits in the TI datasheet before layout.
推荐
Industrial Measurement Systems
A CD4052B can route several process or instrumentation signals into a shared analog front end when the design must preserve a common measurement path. The verified 20 V product positioning and logic-level conversion make it relevant to industrial control systems, provided the selected signal amplitude and control levels remain within the exact datasheet limits. Because the part is an analog multiplexer rather than an instrumentation amplifier, the system must account for switch on-resistance, leakage, settling time, source impedance, and ADC acquisition timing. The inhibit input should be driven deliberately during calibration and reset states. Confirm surge protection and grounding separately; those protections are not established by the supplied data.
推荐
Audio Channel Selection
The CD4052B can be evaluated for audio-source selection when the signal amplitude and bandwidth fit the analog switch characteristics. The verified 4:1 architecture can reduce the number of physical inputs reaching an amplifier or codec, while the inhibit function provides a defined disable state. The key design trade-off is that the verified CD4052BPWR variant reports 240 ohm on-resistance, which can interact with the source and load impedance and should be included in the gain, attenuation, and distortion budget. Pop, switching transients, ground bounce, and control timing also require testing. The exact CD4052B audio-frequency limits were not supplied and must be checked in the manufacturer datasheet.
推荐
Automotive Signal Routing
CD4052B can be considered for low-voltage automotive signal-routing prototypes, but the supplied data does not confirm AEC-Q100 qualification or transient ruggedness for the base MPN. The verified TI E2E discussion describes a CD4052B used in an automotive LIN circuit and separately asks about alternatives with better surge ratings, so qualification is a critical decision point. Automotive production designs should verify the exact suffix, temperature grade, ESD and transient ratings, operating voltage, and protection strategy. Logic-level conversion can help interface the control section, but it does not replace input protection. Do not approve a production substitution based only on the MPN family name.
推荐
Communications Interface Routing
The CD4052B can route low-frequency control or analog communication signals when a compact, CMOS-compatible multiplexer is sufficient. Its binary select inputs allow a controller to choose one of four terminals in each of two switched paths, reducing duplicated front-end circuitry. The supplied material does not provide bandwidth, insertion-loss, or switching-time values, so high-speed RF or high-data-rate digital routing should not be assumed. Designers should use the exact datasheet AC characteristics, account for 240 ohm on-resistance where applicable to CD4052BPWR, and keep control traces away from sensitive analog paths. A modern low-voltage mux may be preferable when lower resistance or faster transitions are needed.
推荐
Control-System Signal Isolation
The CD4052B can be used to select one of several control or feedback signals while the inhibit input provides a basic disable function for reset and maintenance states. This is useful in systems where several analog setpoints or feedback nodes share one controller input. The design must define logic states during power-up, reset, fault, and shutdown so that the common terminal is never exposed to an unintended voltage. Because the verified data does not include leakage, fault-current, or package-specific pinout values for the base MPN, those parameters must be verified before using the device in safety-related or high-energy control paths. Add external clamping or series impedance where needed.

关键差异点
- Established 4:1, 2-channel multiplexing function （对比 TMUX4052)
- Logic-level conversion in the verified product description （对比 SN74LV4052A)
- CD4052BPWR package option （对比 CD74HC4052M)
设计说明
Do not treat the 20 V identifier in the verified TI product description as the complete CD4052B operating-voltage specification. The supplied data does not include the VDD range, control-input thresholds, analog signal limits, or absolute-maximum ratings. Before schematic sign-off, select the exact TI ordering option and check the manufacturer datasheet for supply voltage, signal voltage, power dissipation, and package-specific limits.
Use the verified 240 ohm on-resistance value as a starting point only for the CD4052BPWR variant. Estimate the resulting divider attenuation with the actual source and load impedance, and include switch capacitance, leakage, control transition time, and ADC acquisition time where applicable. The CD4052B is not automatically suitable for high-frequency or high-impedance sensor signals.
For CD4052BPWR, follow the manufacturer’s 16-TSSOP footprint exactly and route the analog common terminal and switched terminals away from high-current switching paths. Keep the control traces short and return the inhibit signal to a defined logic state during reset. The base CD4052B MPN does not identify a package in the supplied data, so do not copy the CD4052BPWR footprint to another suffix without verification.
Calculate analog-switch power loss from the actual supply voltage, selected-path voltage, and load current rather than assuming the nominal 20 V rating applies continuously. Use the verified CD4052BPWR 240 ohm figure only when that exact variant is selected. The datasheet’s absolute-maximum and operating-current limits must govern thermal and supply design.
