CD4053BE Visão geral
An analog multiplexer is a switching IC that connects one of several physical signal paths to a shared resource. The CD4053BE belongs to the CD4000 CMOS logic family and combines three independent SPDT switch sections with address and enable control inputs. Its logic-level conversion feature helps bridge different voltage domains when the selected signals and control levels are compatible with the device’s published limits.
Key verified features include a 20 V supply-related operating designation, three 2:1 switch circuits, 240 ohm on-resistance, 16-pin PDIP construction, and a temperature range from -55 °C to +125 °C. The 2:1 configuration is appropriate for selecting between two sources per channel rather than scanning a larger number of inputs. The DIP package favors breadboards, legacy industrial boards, prototype fixtures, and through-hole assemblies where a surface-mount package would be unsuitable.
The CD4053B is specified as a CMOS analog multiplexer with logic-level conversion. Its control interface determines which analog terminal is connected to the common terminal of each section. Designers should account for signal amplitude, supply voltage, control logic levels, switch resistance, leakage, and the dynamic behavior of the connected source and destination circuits. The verified data does not provide complete timing, leakage, capacitance, or current-limit values, so those parameters should be taken from the manufacturer datasheet before final release.
Typical applications include selecting between two sensors, routing one of two audio or communications sources, switching measurement channels in test equipment, and implementing sample-selection networks in industrial control systems. The device can reduce the number of external connections when several controlled signals share a downstream amplifier, converter, or controller input.
A key design consideration is ensuring that the selected signal remains within the device’s published analog and control limits throughout operation. Avoid using the multiplexer as a power switch unless the relevant current, voltage, and transient requirements have been verified. Also account for off-channel injection and switch resistance when designing precision measurement paths.
This page combines the verified Texas Instruments product data, distributor identification, practical application guidance, and a structured comparison framework. It also distinguishes confirmed CD4053BE attributes from parameters that require the complete manufacturer datasheet for engineering sign-off.

Aplicações típicas
CD4053BE é adequado para 6 aplicaçãos: Two-Source Sensor Selection, Test and Measurement Signal Routing, Industrial Control Signal Selection, Audio Source Multiplexing, Communication Input Multiplexing, Legacy Control-System Upgrade.
Two-Source Sensor Selection
The CD4053BE suits instrumentation that must select between two sensor outputs without duplicating the downstream amplifier or converter. Each 2:1 section can route one of two analog inputs to a shared measurement node, and the 240 ohm on-resistance should be included when calculating loading and attenuation. Because the verified data confirms three channels, it can coordinate several related selections. Confirm supply levels, control thresholds, leakage, and signal swing in the Texas Instruments datasheet before connecting precision sensors.
Recomendado
Test and Measurement Signal Routing
The CD4053BE is useful in test fixtures where two stimulus or return paths must be selected before a common measurement chain. Its three independent 2:1 sections allow one multiplexer to manage related signal pairs while reducing external routing. The 16-pin PDIP package is convenient for legacy instruments, breadboard prototypes, and through-hole test boards. Keep analog traces short, separate them from switching-current paths, and verify the 240 ohm resistance against the measurement accuracy budget.
Recomendado
Industrial Control Signal Selection
The CD4053BE can select between two control or feedback signals in an industrial board when a shared actuator, amplifier, or diagnostic input is needed. The triple 2:1 arrangement reduces duplicated switching hardware, while logic-level conversion may assist compatible control interfaces. The verified operating-temperature range is -55 °C to +125 °C, which supports temperature-tolerant designs, but exact supply and control limits must be checked. Use a stable reference and ground plane to prevent switching transients from affecting selected signals.
Recomendado
Audio Source Multiplexing
The CD4053BE can route two audio-related analog sources per section into a common audio-processing path, provided the source impedance and signal amplitude remain suitable. The 240 ohm on-resistance may interact with the input impedance of the following amplifier, so calculate the resulting level loss and distortion margin. The verified logic-level conversion feature can simplify compatible control sequencing, but it does not replace verification of THD, noise, bandwidth, and signal-swing specifications.
Recomendado
Communication Input Multiplexing
The CD4053BE can choose between two low-frequency communication or conditioning paths before a shared receiver stage. Its three-channel architecture permits multiple related selections, while the logic-level conversion feature supports compatible control interfaces. The verified 20 V designation should not be interpreted as a complete electrical operating range without the manufacturer datasheet. Validate input capacitance, leakage, switching transients, and the source impedance before using the mux near high-speed edges or low-level signals.
Recomendado
Legacy Control-System Upgrade
The 16-pin PDIP package makes CD4053BE suitable for maintaining or refurbishing older through-hole control boards that need two-source selection for alarm, setpoint, or feedback signals. The -55 °C to +125 °C operating range is useful for broad industrial environments, but compliance and exact logic thresholds remain unconfirmed in the supplied data. Before installation, compare the replacement pinout, supply arrangement, and select truth table with the original board documentation. Use a socket when field replacement and future maintenance are priorities.

Principais diferenciais
- Three integrated 2:1 analog selections in one IC (vs MC14053BCPG)
- Confirmed Texas Instruments product-page support (vs MC14053BCPG)
- Verified 240 ohm on-resistance value (vs CD4053BM96)
Notas de projeto
Treat the 240 ohm on-resistance as part of the analog signal path. For a source resistance of Rs and load resistance RL, the switch forms a divider with the receiving input; calculate the resulting gain before selecting the downstream impedance. Keep selected and unselected traces away from clocks, relays, and power-converter switching nodes to reduce capacitive and inductive coupling. If the mux sits next to a precision ADC or amplifier, use a short return path and a quiet ground reference.
Use a mechanically verified 16-pin PDIP footprint and confirm the package drawing against the current Texas Instruments documentation before layout release. Place bypass decoupling close to the device supply pins, route analog terminals away from high-current paths, and provide adequate ground-plane continuity. The verified data does not include the individual pinout or recommended layout, so do not assign PCB connections from a generic CD4053 diagram without checking the selected package revision.
Do not assume that logic-level conversion makes every 5 V or 3.3 V interface safe. Verify VIH, VIL, supply voltage, input current, analog signal limits, and power-off behavior in the complete datasheet. Also do not use the CD4053BE as a general power switch based only on its nominal 20 V designation. Its 240 ohm resistance can create large voltage drops and heating, and no SOA or power-switch rating was verified.
Informações de conformidade
The supplied verified excerpts do not state RoHS, REACH, lead-free, halogen-free, conflict-mineral, or automotive qualification status for CD4053BE. Confirm the current Texas Instruments product documentation and ordering information before making a compliance claim.
