CD4052BF Présentation
An analog multiplexer is a digitally controlled switch that connects one of several analog terminals to a common terminal. A demultiplexer reverses this direction by connecting one common signal path to a selected output. The CD4052 family provides two such channels, making it suitable for routing differential signals, paired sensor outputs, sampled analog inputs, and control signals in test equipment. Its CMOS implementation is intended for low-power logic systems and low-voltage analog-signal switching.
The verified CD4052BF datasheet search result identifies a 16-CDIP package and a -55 °C to 125 °C temperature range. The family documentation also describes low ON impedance and very low OFF leakage current. These characteristics help preserve signal integrity when the device switches analog nodes. The logic-level conversion feature is useful when the control logic operates from a supply different from the analog-signal supply.
The CD4052BF can be used in data acquisition, instrumentation, communications, embedded control, and analog signal-routing systems. It can select one of multiple input channels into a shared signal path, or distribute one signal path among multiple destinations. The differential two-channel arrangement is particularly useful for systems that carry two related signals, such as complementary sensor outputs or paired communication lines.
Designers should verify the exact pin functions, control truth table, allowed supply combinations, input and output voltage limits, and switch timing from the manufacturer datasheet before layout. Because the available verified results do not provide complete electrical tables, missing values are explicitly marked in the specification section rather than estimated. Decoupling, control-signal timing, unused-channel termination, and analog signal-range checks remain important implementation considerations.
This page combines verified distributor and manufacturer-linked results with structured application guidance and a conservative replacement assessment. Pricing, lifecycle status, electrical limits, and complete pin-level details should be reconfirmed against the current manufacturer documentation before production release.

Applications typiques
CD4052BF convient pour 6 applications: Multiplexed Sensor Acquisition, Differential Signal Routing, Data Acquisition Front Ends, Test and Measurement Equipment, Embedded Control Signal Selection, Legacy Communication Interface Routing.
Multiplexed Sensor Acquisition
The CD4052BF fits multiplexed sensor acquisition because its dual 4-channel CMOS structure can route paired analog signals through two coordinated switching sections. The verified family documentation identifies low ON impedance and very low OFF leakage, which helps preserve sensor amplitude when a selected channel is connected. Use the selector logic to address one of four channel groups, then allow the downstream amplifier or ADC to acquire the selected signal. The 16-CDIP package suits through-hole instrumentation, but engineers must verify switch settling time, input capacitance, signal range, and the exact truth table because those details were not included in the supplied search data.
Recommandé
Differential Signal Routing
The CD4052BF is appropriate for differential signal routing when a system must select one of several paired analog connections without changing the through-hole board layout. Its two related switching sections can carry complementary or otherwise paired signals, reducing the need for separate multiplexing arrangements. The verified manufacturer-linked result identifies a differential 4-channel multiplexer/demultiplexer with logic-level conversion. In implementation, preserve signal symmetry, keep both channels on compatible supply domains, and verify that the selected signal remains within the permitted analog range. The available data does not specify insertion loss or channel-to-channel crosstalk, so those values require direct datasheet confirmation.
Recommandé
Data Acquisition Front Ends
The CD4052BF can serve as an analog channel selector in a data-acquisition front end where several inputs must share one downstream amplifier or converter. The four-channel-per-section arrangement supports structured measurement systems, while logic-level conversion helps interface the selector to compatible digital control circuitry. Keep the analog path short, provide the required bypass and protection, and account for source impedance and settling time before the next conversion begins. The verified Mouser result confirms the 16-CDIP package and -55 °C to 125 °C operating range, but it does not provide complete switching-time or leakage tables, so those parameters must be checked before selecting sample-rate limits.
Recommandé
Test and Measurement Equipment
The CD4052BF is useful in test and measurement equipment when several analog nodes must be routed to a shared instrument input. Its CMOS switching architecture and logic-level conversion make it a natural fit for legacy or mixed-voltage control systems that need analog selection rather than high-speed RF switching. The device can reduce the number of discrete routing paths while keeping the external board in a through-hole format. Validate insertion loss, off leakage, switching speed, and maximum analog voltage against the exact datasheet because those values were not supplied in the verified search excerpts. Use shielding and guarding if the measured source has high impedance or the signal is especially noise-sensitive.
Recommandé
Embedded Control Signal Selection
The CD4052BF can select control or feedback signals in an embedded control system when the designer needs a compact analog routing function in a through-hole design. The two four-channel sections allow related control, status, or setpoint signals to be addressed from a common path. Use the select inputs only within their specified logic thresholds and ensure that the selected source and destination remain within the allowed voltage range. If the embedded controller uses a modern low-voltage I/O rail, the logic-level-conversion feature must be checked against the actual supply combination. Firmware should also honor the required address setup and hold times from the manufacturer timing data.
Recommandé
Legacy Communication Interface Routing
The CD4052BF may be used in legacy communication equipment to route compatible analog or logic-level signal paths through a shared connector or transceiver interface. The part's logic-level conversion and dual 4-channel structure are useful when control signals and paired data paths need coordinated selection, especially in older through-hole systems. Designers must verify that the selected supply arrangement supports both the analog signal and control inputs, and that any connected transceiver remains within the channel's voltage and leakage limits. Because the available results do not provide a complete modern-equivalent comparison, the safest use is as a functional routing element inside an existing CD4052B-family design rather than an unverified substitute for a newer communications switch.

Notes de conception
Decouple each supply rail near the device with the capacitance and voltage rating required by the manufacturer datasheet. Because CD4052BF is a CMOS analog multiplexer, supply transitions can affect control thresholds and analog switching behavior. Confirm the VDD, VSS, and VEE relationship used by the circuit, keep control levels within their specified range, and avoid allowing unused supply pins to float. The verified material gives broad family conditions but does not provide complete supply-limit tables, so do not infer a rail combination from a generic CD4000B example.
Route the analog common and channel traces away from selector and clock-like digital control nets whenever possible. Keep the mux/demux device close to the source or destination being selected, use a continuous ground reference, and place protection components where they will not add unwanted leakage or capacitance to high-impedance sources. The verified data identifies low OFF leakage and low ON impedance as family characteristics, but trace resistance, connector leakage, and adjacent-channel coupling can still determine practical signal integrity.
Do not treat CD4052BF as a modern low-Ron, high-speed analog switch. The provided verification identifies a 20 V peak-to-peak control capability under specified conditions, but it does not provide complete insertion loss, bandwidth, switching-time, or absolute-maximum tables. Before using it in precision acquisition or signal-chain equipment, verify the selected channel's voltage, source impedance, settling time, leakage, and control timing against the actual datasheet. Also confirm that CD4052B-family suffixes and CD4000-family alternatives have identical pin functions before replacing the part.
A 16-CDIP footprint should not be assumed interchangeable with a 14-pin SOIC alternative. The comparison result for CD74HC4066M96 identifies a different package, pin count, and switching arrangement, so it would require PCB changes and design verification rather than drop-in replacement. For any proposed substitute, compare physical lead spacing, pin numbering, common terminals, channel terminals, select polarity, supply pins, and maximum analog voltage. The alternatives in this record are candidates requiring manufacturer cross-reference confirmation, not guaranteed production approvals.
