MPC506AP - 16:1, ±15V Analog Multiplexer | Texas Instruments
MPN: MPC506AP ✗ End of LifeMPC506AP Overview
An analog multiplexer is a switching interface that connects one common terminal to one selected input terminal. The MPC506AP belongs to the analog-switch and multiplexer hierarchy, where CMOS low-power switching, channel isolation, break-before-make behavior, and signal-range management are central design considerations. Its 16-channel organization makes it useful for reducing the number of external connections in multichannel analog systems.
Key verified features include a 16:1 configuration, one switch circuit, approximately 1.5 kOhm on-resistance, a 28-PDIP package, analog overvoltage protection, no channel interaction during overvoltage, break-before-make switching, an analog signal range of ±15 V, and typical standby power of 7.5 mW. The input protection feature helps preserve signal fidelity when an analog input exceeds a supply voltage, while the multiplexer architecture provides a controlled way to share a downstream analog resource.
The device is a 16-channel single-ended analog multiplexer and is associated with the MPC506A family, which uses CMOS multiplexing for general-purpose signal selection. The verified data also identifies MPC506A as having input overvoltage protection. Exact switching timing, channel capacitance, leakage, logic thresholds, supply-current limits, and absolute maximum ratings were not supplied in the verified excerpts, so those parameters should be confirmed in the manufacturer datasheet before design release.
Typical applications include multiplexed sensor acquisition, data acquisition systems, instrumentation, industrial control, analog test equipment, and communications or control boards that need to route several low-frequency analog signals to one processing channel. The ±15 V analog range is especially relevant for bipolar industrial signals, provided the system observes the device's verified supply and input limits.
Designers should confirm the exact pinout, truth table, enable polarity, supply requirements, and timing from the MPC506A datasheet. PCB layout should keep analog traces short, provide a stable ground reference, and account for the 28-pin through-hole package. Because the mux adds on-resistance and switching transients, the downstream amplifier or converter must have sufficient input bandwidth and settling behavior.
This page consolidates the verified manufacturer and distributor descriptions, package identity, channel count, resistance, protection features, and application guidance into a design-oriented component reference while clearly separating unavailable parameters from sourced facts.

Typical Applications
MPC506AP is suitable for 6 applications: Multiplexed Sensor Acquisition, Industrial Instrumentation, Data Acquisition Systems, Analog Test Equipment, Control Signal Routing, Bipolar Signal Conditioning.
Multiplexed Sensor Acquisition
The MPC506AP fits sensor acquisition systems that must bring 16 single-ended sensor signals to one shared analog input. Its verified 16-channel organization reduces the number of front-end connections, while the listed 1.5 kOhm on-resistance should be included in the source-impedance and gain-error budget. The input overvoltage-protection feature can improve fault tolerance when a sensor or connected circuit drives an input above a supply rail. Designers should verify settling time, leakage, and accuracy against the actual sensor bandwidth before committing to the mux path.
Recommended
Industrial Instrumentation
For industrial instrumentation, the MPC506AP can route multiple bipolar process signals when the selected channels are within its verified ±15 V analog signal range. The overvoltage-protection architecture helps isolate an over-range input from other channels, and break-before-make switching supports controlled channel transitions. A practical design should use a solid ground plane, short analog traces, input protection appropriate to the field wiring, and downstream filtering after the multiplexer. Exact common-mode, leakage, and timing limits must come from the manufacturer datasheet.
Recommended
Data Acquisition Systems
The MPC506AP is suitable for a multiplexed data-acquisition front end when one processing channel must sample 16 single-ended inputs. The 16:1 configuration helps scale channel count, but the listed 1.5 kOhm on-resistance and any unverified switching transient can reduce accuracy or require additional acquisition time. Use a front-end buffer when source impedance is high, maintain a low-impedance reference path, and calibrate channel gain and offset in software. The verified excerpts do not provide settling-time or channel-capacitance data, so the ADC acquisition window should not be guessed.
Recommended
Analog Test Equipment
In analog test equipment, the MPC506AP can connect one of 16 test points to a common measurement amplifier or instrument input. Its single-ended architecture is convenient for repetitive channel selection, while the verified overvoltage-protection function can help contain unexpected input excursions. The designer should account for the 1.5 kOhm listed on-resistance when interpreting high-impedance probes and should use a controlled reset or valid interval after changing channels. Calibration of each selected path is recommended because mux resistance and leakage can contribute to channel-dependent error.
Recommended
Control Signal Routing
The MPC506AP can route low-frequency control or feedback signals when the system has many selectable analog nodes and one shared actuator-control input. Its 16-channel single-ended organization simplifies wiring and can reduce duplicated analog front ends. Break-before-make behavior should be considered during state transitions so that two control paths are not unintentionally connected during a changeover. Confirm the logic truth table, enable polarity, and maximum input conditions from the manufacturer datasheet before using the mux for safety-critical control loops.
Recommended
Bipolar Signal Conditioning
The MPC506AP can be used in bipolar signal-conditioning systems where several inputs share a ±15 V range. The common signal path should be designed so the mux's listed on-resistance does not create unacceptable attenuation with the source and downstream input impedance. Input protection, grounding, and cable transients are especially important in industrial environments because the verified excerpts do not provide complete absolute maximum ratings. A buffer or amplifier after the mux can improve drive capability, while filtering should be placed according to the required signal bandwidth.

- Established 28-PDIP package identity (vs ADG506AKN)
Design Notes
Use a continuous ground plane and route the analog common, channel inputs, and output as short, well-controlled traces in the 28-PDIP layout. Keep digital select or enable routing away from sensitive analog nodes where practical, and place any input filtering close to the protected pin. Because the verified package is through-hole 28-PDIP, check lead spacing and connector clearance against the final PCB footprint before fabrication.
Do not infer pin functions from the package position or from the similar MPC507A architecture. The verified excerpts confirm the 28-PDIP package and 16-channel single-ended function but do not provide the complete pin table, enable polarity, truth table, or absolute maximum ratings. Obtain the official MPC506A datasheet and cross-check those items before connecting external signals, especially when a related family member is considered as a replacement.
Include the listed 1.5 kOhm on-resistance when calculating divider ratios and source loading, and account for mux leakage and capacitance using the manufacturer values. For an ADC front end, allow sufficient acquisition and settling time after changing channels rather than sampling immediately after the select transition. The supplied data does not include switching time or capacitance, so those values must be measured or obtained from the datasheet before setting the timing budget.
Compliance Information
Compliance status was not included in the verified excerpts. The component is an industrial or general-purpose analog multiplexer; AEC-Q100 is marked not_applicable because automotive qualification was not stated.
