MCZ33904C3EKR2 - SBC, 2x 3.3V/400mA LDO, HS CAN, 32-SOIC-EP | NXP
The NXP MCZ33904C3EKR2 is a second-generation System Basis Chip (SBC) integrating two 3.3 V/400 mA LDO regulators, a high-speed CAN transceiver compliant with ISO 11898-2 and ISO 11898-5, four wake-up inputs, and advanced fault diagnostics, all housed in a 32-pin SOIC-EP (exposed pad) package supplied on tape and reel. The MCZ33904 family operates from a 5.5 V to 28 V supply rail, supporting 12 V and 24 V automotive bus systems while offering Normal, Sleep, and Stop power modes optimized for ECU standby current. Two independent 3.3 V LDO regulators (V1 and V2) are capable of delivering up to 400 mA each, providing power to an MCU and companion circuitry such as sensors and CAN transceivers. A System Basis Chip (SBC) is a power management and communication integrated circuit that consolidates multiple discrete functions - typically voltage regulators, a CAN/LIN transceiver, wake-up logic, and supervisory features - into a single device. By integrating these functions, an SBC reduces PCB area, simplifies EMC compliance, and provides deterministic reset and watchdog behavior for automotive ECUs. SBCs sit one level above standalone LDOs and below full PMICs in the automotive power-tree hierarchy, occupying the role of the local ECU supply and bus interface. Key features include enhanced high-speed CAN physical layer with local and bus failure diagnostics, selectable Normal/Sleep/Stop modes for low-Iq standby, configurable window watchdog, and fail-safe operation mode. The 32-SOIC-EP exposed pad reduces thermal resistance and improves reliability in harsh under-hood environments. Built-in protection includes over-temperature shutdown, over-current limiting on each LDO, and bus dominant time-out for the CAN driver. The architecture combines an automotive-grade bipolar/CMOS process, an internal 3.3 V bandgap reference, and low-Iq charge pumps to meet strict OEM quiescent-current budgets (<100 uA in Sleep). The MCZ33904C3EKR2 variant belongs to the 'C3' suffix family, which configures the V2 LDO for 5 V operation or specific ECU power-rail allocations, and the 'EK' indicates the SOIC-EP package option. Typical applications include 12 V automotive body control modules, instrument clusters, gateway ECUs, HVAC controllers, and industrial CAN nodes. The dual 3.3 V rails cleanly power an MCU plus a 5 V-tolerant sensor stage, while the integrated HS-CAN eliminates the need for a standalone transceiver. In Sleep mode the device draws microamp-level quiescent current, supporting always-on wake-up via the WKUP pins for CAN or LIN traffic. When designing with this SBC, place the exposed pad solder stencil to provide at least 50 mm squared of copper to keep junction temperature within range at 28 V worst-case load. Decouple each V1/V2 LDO output with a 1 uF to 10 uF low-ESR ceramic placed within 5 mm of the relevant pin; mis-typed or distant capacitors cause output ripple and regulator instability.

MCZ33972AEK - Multi-Switch Detection SPI Interface, 8-26V, 32-SOIC-EP | NXP
The NXP MCZ33972AEK is a multiple switch detection interface with suppressed wake-up, designed to detect the closing and opening of up to 22 switch contacts through an SPI (Serial Peripheral Interface) bus, housed in a 32-pin SOIC-EP (exposed pad) package. It operates over a wide supply voltage range of 8 V to 26 V and integrates a dual H-bridge coil driver with associated control logic, enabling direct stepper motor gauge drive alongside switch monitoring. What is a multiple switch detection interface? This category of mixed-signal interface IC sits between low-current mechanical switches (buttons, door switches, sensor contacts) and a host microcontroller. It replaces dozens of discrete pull-up resistors and input pins by multiplexing the switch states onto an SPI bus, while the suppressed wake-up function prevents the host MCU from being awakened by spurious or bouncing switch events. In the system hierarchy, MCZ33972AEK is a specialized interface IC within the broader power management and body electronics domain. Key features of the MCZ33972AEK include programmable wetting current for each input (typically 2 mA, 6 mA, or 16 mA selectable), built-in switch debounce and over-voltage protection on each input pin, and an ultra-low quiescent current in Sleep mode that makes it ideal for automotive body controllers that must meet stringent quiescent-current budgets during key-off. The exposed pad on the 32-SOIC package reduces thermal resistance and improves reliability under sustained current loads. The device operates in two modes: Normal mode supplies switch contacts with pull-up or pull-down current while continuously monitoring switch state changes for SPI reporting; Sleep mode disables most internal circuitry to draw minimum current until a qualified wake-up event occurs. The wetting current is programmable per channel via SPI, allowing the same IC to interface with both dry contacts and solid-state sensor outputs. Typical applications include automotive body control modules (detecting door, hood and trunk switches), instrument cluster switch matrices, HVAC control panels, and industrial control panels with multiple mechanical inputs. In each case the MCZ33972AEK replaces 22 discrete GPIO channels and their pull-up networks with a single SPI-controlled IC. When designing with this device, calculate worst-case power dissipation from VIN_max and the number of switches simultaneously sourcing wetting current. Place the exposed pad on a minimum 1 square inch copper pour to keep junction temperature within the -40C to +125C automotive operating range. Decouple VCC with a 100 nF ceramic capacitor placed within 5 mm of the supply pin. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, including cross-brand substitute guidance and a parameter comparison table for engineers selecting multi-channel switch monitor ICs.
MCZ33972AEKR2 - SPI Switch Detection Interface, 32-SOIC EP | NXP
The NXP MCZ33972AEKR2 is a multiple switch detection interface with suppressed wake-up, housed in a 32-pin SOIC-EP (exposed pad) package. It communicates over an SPI bus and operates from an 8 V to 26 V supply, making it a direct fit for 12 V and 24 V automotive body and chassis systems. A switch detection interface is a mixed-signal IC that multiplexes multiple mechanical or electronic switch inputs into a single serial data stream for a microcontroller. In the broader system hierarchy it sits below the MCU and above the physical switch network, forming part of the body-electronics domain of automotive electronics. Suppressed wake-up means the device can ignore transient switch events and only assert the wake-up interrupt after a programmed debounce window has passed, reducing false ECU wake-ups. Key features include support for up to 7 direct switch inputs with programmable wetting current, on-chip ESD protection, a low-power standby mode with interrupt wake-up capability, and a 32-bit SPI status register reporting switch state, supply voltage, and fault conditions. The exposed thermal pad on the 32-SOIC package provides a low theta-JA path for dissipating transient load events on the supply pin. From an architectural standpoint the device combines an analog multiplexer, a current source for switch wetting, an analog-to-digital conversion channel for supply monitoring, and a standard SPI slave interface. The same die serves multiple package variants in the 33972 family, allowing PCB reuse across part numbers. The wide 8 V to 26 V analog supply tolerance makes it compatible with cranking transients and load-dump events typical of automotive 12 V rails. Typical applications include automotive body controllers detecting door, hood, and trunk switches, HVAC control panels reading multiple user inputs, and industrial control panels requiring debounced digital inputs over a single SPI bus. The suppressed wake-up feature reduces quiescent current draw by preventing spurious ECU wake-ups from switch bounce or EMI. When designing with this part, place 100 nF decoupling close to VCC and connect the exposed pad to a thermal copper pour of at least 1 square inch to keep junction temperature within SOA during fault conditions. The wake-up timing is set by an external capacitor; consult the manufacturer datasheet for the recommended range. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, supporting faster sourcing decisions for automotive and industrial switch-interface designs.
MCZ33972AEW - 22-Switch SPI Interface, 8-26V | NXP
The NXP MCZ33972AEW is a Multiple Switch Detection Interface with Suppressed Wake-up that monitors up to 22 switch contacts in automotive and industrial systems, reporting state through an SPI (Serial Peripheral Interface) to the host MCU. Housed in a 32-SOIC (7.50 mm wide, 0.295 inch body) package, the device operates from an 8 V to 26 V supply range and supports both 3.3 V and 5 V logic families via its VDD logic rail. A switch monitor IC belongs to the broader category of interface ICs and mixed-signal peripherals, sitting between the power-management domain and the digital logic domain in a vehicle or industrial ECU. Multiple switch detection interfaces aggregate wet or dry switch contacts and convert them into a serial stream, freeing up MCU GPIO pins, reducing wiring, and providing deterministic wake-up behavior for body, chassis, and body-control modules. The 33972 family is the de-facto NXP platform for this function, succeeding earlier MC33800/MC33996 scan-only parts by adding programmable wetting current, programmable debounce, and a low-quiescent Sleep mode that enables microamp-level standby currents mandated by modern vehicle parasitic-drain budgets. Key features include: detection of 22 switch inputs, programmable wetting source/sink current on a per-input basis, a 22-to-1 analog multiplexer that can be routed to a dedicated AMUX output pin for ADC measurement, integrated 5 V LDO for VDD logic supply, programmable debounce filter, wake-up capability via a dedicated WK input, two operating modes (Normal and Sleep), and selectable SPI clock polarity/phase. The 32-SOIC wide-body footprint simplifies PCB layout versus smaller 32-QFN variants for hand-rework prototypes. Technically, the device uses a current-source/pull-down architecture for switch detection: each input is biased with a programmable current and the resulting voltage is compared against a threshold. The host MCU programs configuration, threshold, and debounce registers via SPI; switch-change events generate an interrupt on the INTB pin, allowing the MCU to enter Sleep between interrupts for very low average current. The integrated 22-to-1 AMUX enables precise analog measurement of each switch pin via the host ADC, supporting diagnostics for stuck-open, stuck-shorted, and leakage conditions. Typical applications include automotive body control modules (BCM), steering-wheel switch clusters, HVAC control panels, door modules, seat controllers, and industrial PLC switch and sensor interfaces. The wide 8-26 V supply tolerance covers 12 V and 24 V battery rails directly without pre-regulation. Design with the part by leaving the WK pin accessible for hardware wake-up from Sleep, choosing wetting current per switch type (typically 2-16 mA), and following the NXP recommended layout to keep the SPI traces short and shielded from the switch-input harness. The 32-SOIC wide body simplifies soldering and rework versus QFN but requires slightly more board area; the alternative pin variant MCZ33972AEK uses a 32-SOIC narrow body. This page synthesizes DigiKey and Mouser distributor pricing, drop-in NXP same-family alternatives, and practical design notes not found in the manufacturer datasheet.
MCZ33972EWR2 - 22-Ch Switch Monitor SPI Interface | NXP
The NXP MCZ33972EWR2 is a Multiple Switch Detection Interface (MSDI) IC that monitors up to 22 switch contacts and reports their open/closed state to a microcontroller through a 16-bit SPI (Serial Peripheral Interface). Housed in a 32-pin SOIC wide-body package (7.50 mm), it operates from an 8 V to 26 V supply and includes suppressed-wake-up functionality, programmable wetting current, and a 22-to-1 analog multiplexer for sequential switch voltage readout. A Multiple Switch Detection Interface (MSDI) is a type of mixed-signal automotive interface IC that combines analog input multiplexing, programmable current sources, threshold comparators, and a digital serial interface into a single device. In the system hierarchy it belongs to Interface ICs > Specialized Interface ICs, bridging low-level mechanical switches to digital logic. Its primary purpose is to replace dozens of discrete pull-ups, comparators, and wiring with one rugged, AEC-qualified IC, which is critical for body controllers, HVAC panels, and steering-wheel switch clusters. Key features of the MCZ33972EWR2 include detection of 22 switch inputs, a 16-bit SPI output word, user-selectable switch-to-ground or switch-to-battery configuration, programmable wetting current (2 mA / 6 mA / 12 mA / 16 mA typical), and an integrated 22:1 analog MUX output for ratiometric measurement. The wake-up feature pulses a current briefly through each switch on a programmed interval, then returns to a low-Iq Sleep mode, drastically reducing quiescent current in parked-vehicle applications. Normal mode allows continuous monitoring at full speed and full programming access. The device uses an internal 5 V regulator derived from V_PWR to power analog and digital blocks, and provides an interrupt output (INT) to wake the host MCU on any switch state change. The on-chip 22-to-1 analog multiplexer allows a single ADC on the MCU to sequentially read each switch node for ratiometric diagnostics (open circuit, short to battery, short to ground). The architecture is designed to tolerate 40 V load-dump transients common in 12 V automotive networks, with reverse-battery protection on V_PWR. Typical applications include automotive body controllers detecting door, hood, trunk and seatbelt switches, HVAC control panels reading push-buttons and rotary encoders, steering-wheel switch clusters, instrument-cluster switch input, and industrial control panels with multiple contact closures. Its suppressed wake-up and low quiescent current make it well-suited to any battery-powered application where the system must wake on a switch event without continuously drawing power. Designers should note that the 32-SOIC package requires thermal relief and adequate copper for the exposed-pad power-dissipation path, and that the analog MUX output should be buffered if more than a few hundred pF of capacitance is present on the trace. PCB layout must keep the analog MUX trace away from switching power traces to preserve diagnostic accuracy.

MCZ33975EK - 22-Channel Switch Detection SPI Interface | NXP
The NXP MCZ33975EK is a 22-channel multiple switch detection interface with suppressed wake-up and 32 mA wetting current, housed in a 32-pin SOIC-EP (Exposed Pad) package. It communicates with a host MCU through an SPI (Serial Peripheral Interface) bus and is qualified to AEC-Q100 automotive standards. A multiple switch detection interface is a specialized analog/digital IC that scans a large array of mechanical or electronic switch contacts and reports their open/closed state to a microcontroller. This category sits within the broader hierarchy of interface ICs -> specialized interfaces -> automotive body electronics drivers. Unlike simple GPIO expanders, switch-detection ICs include programmable wetting current sources, debounce timers, and wake-up suppression logic that allows the rest of the ECU to remain in low-power sleep until a defined switch event occurs. Key features include detection of up to 22 switch contacts, a 5.5 V to 28 V supply range suited to 12 V automotive rails with load-dump margin, 32 mA programmable wetting current per input to prevent oxidation on mechanical contacts, integrated SPI reporting with interrupt capability, and programmable wake-up behavior. The exposed thermal pad on the 32-SOIC-EP package reduces junction-to-ambient thermal resistance, allowing sustained operation at full wetting-current load across all 22 channels. The device is built on a high-voltage BCD (Bipolar-CMOS-DMOS) process that supports direct connection to automotive battery nodes without external level shifting. Each of the 22 input channels integrates a wetting-current source, comparator, and debounce state machine. The suppressed wake-up feature allows the IC to ignore brief or noisy switch events and only interrupt the MCU when a genuine, sustained contact transition occurs, dramatically reducing ECU sleep-mode current in body-comfort applications. Typical applications include automotive body control modules reading door, hood, and trunk ajar switches, climate-control panel buttons, seat-occupancy and buckle switches, lighting controls, and any distributed switch matrix that must communicate over SPI to an MCU. The wide supply range also supports industrial 24 V control panels with similar switch-scanning needs. When designing with the MCZ33975EK, place 100 nF decoupling capacitors as close as possible to the VBAT and VCC pins, and use the exposed pad as the primary thermal path. Configure the wake-up mask registers to filter mechanical-switch bounce and EMI-induced transients, which are common in automotive wiring harnesses. This page synthesizes distributor pricing, drop-in same-package alternatives, AEC-Q100 compliance context, and practical EMC design notes that go beyond the manufacturer datasheet to accelerate automotive body-electronics design.
MCZ33993EW - 22-Input Switch Detection Interface IC | NXP
The NXP (formerly Freescale Semiconductor) MCZ33993EW is a Multiple Switch Detection Interface (MSDI) IC housed in a 32-pin SOIC wide-body package, designed to detect the closing and opening of up to 22 switch contacts over an SPI (Serial Peripheral Interface). It targets automotive body, chassis, and central body controller applications where a single IC replaces dozens of discrete input-conditioning components. A Multiple Switch Detection Interface (MSDI) is a specialized mixed-signal interface IC that scans and debounces a large array of mechanical or electronic switch contacts. It resides in the broader taxonomy of interface ICs (specialized), which sit between a microcontroller's GPIO and the physical switch contact, offloading the polling, wetting-current sourcing, and diagnostic functions from the MCU. In modern automotive body controllers, MSDIs have largely replaced discrete resistor-capacitor debounce networks, dramatically reducing PCB area and quiescent current. Key features of the MCZ33993EW include: support for 22 grounded switch inputs, programmable wetting current (typically 16 mA per channel), SPI communication up to 4 MHz, configurable switch-to-ground or switch-to-battery modes, integrated thermal shutdown, and reverse-battery protection. The part operates across -40C to +125C ambient and is qualified to AEC-Q100 automotive stress standards. Architecturally, the MCZ33993EW combines 22 analog input channels, a 22:1 analog multiplexer, a programmable current source per channel, and an SPI slave controller. An internal state machine handles programmable wetting-current injection and debounce timing, allowing the host MCU to read a compact switch-status register over SPI rather than polling each GPIO individually. The result is dramatically reduced MCU interrupt and ADC overhead. Typical applications include automotive body control modules (reading door, window, seat, mirror and lighting switches), instrument cluster switch matrices, HVAC control panels, and any node requiring a sealed, robust interface to a large array of low-side or high-side mechanical contacts. Designers should review the application note for wetting-current configuration and the typical schematic in the datasheet to ensure proper series-resistance sizing on each input. This page synthesizes real distributor pricing, drop-in alternatives, and practical design notes for the MCZ33993EW that are not found in the original Freescale datasheet alone.
MIC5800YM-TR - 4-Channel 500mA Latched Driver | Microchip
The Microchip Technology MIC5800YM-TR is a four-channel, parallel-input latched driver with a 500 mA per-channel current rating, a 5 V to 12 V supply range, and a 14-pin SOIC surface-mount package. It combines four CMOS data latches with bipolar Darlington transistor drivers and common CLEAR, STROBE, and OUTPUT ENABLE control circuitry. The device is intended for systems that must retain output states and drive multiple loads from a parallel data bus. A latched driver is a digital interface and power-control IC that captures input data and holds it until a new command changes the stored state. In the broader semiconductor hierarchy, it belongs to the interface-driver category and power management ecosystem. Unlike a general-purpose logic gate that primarily controls signal levels, this device provides buffered control signals with substantially higher current capability for solenoids, relays, lamps, and other electromechanical loads. Its four channels allow one parallel interface to control several loads while preserving state during valid system operating periods. The MIC5800YM-TR provides four active driver channels, 500 mA output current capability, low-side bipolar switching, and common controls for latching and enabling outputs. The SOIC-14 package is designed for surface-mount PCB assembly, while the tape-and-reel ordering suffix supports automated production. The high-voltage, high-current architecture is intended for load-driver applications where logic-level control signals must operate external power devices. According to the manufacturer datasheet, the MIC5800 family contains CMOS data latches, one bipolar Darlington driver per latch, and shared CMOS control logic. Typical applications include relay and solenoid drivers, indicator-lamp control, stepper or motor winding interfaces, and electromechanical systems where multiple outputs must remain latched until commanded. The device can also serve as a general-purpose power-switch interface when the load and supply requirements remain within its specified limits. Because a Darlington output stage introduces a voltage drop and saturation behavior, designers should account for that headroom when selecting loads and supply voltage. The 500 mA rating describes the per-channel capability in the verified distributor description; detailed thermal and continuous-duty limits should be checked against the manufacturer datasheet. For implementation, connect the four parallel data inputs to the host controller or latch input bus, use CLEAR to initialize the latches, use STROBE to transfer data, and use OUTPUT ENABLE to connect or disable the driver outputs. Decoupling capacitors should be placed close to the supply pins, and high-current load paths should be routed with short, wide traces. The device is not a switching regulator and does not provide regulated output voltage; it is a latched power-driver interface. This page combines verified distributor specifications, the manufacturer MIC5800 family description, package details, application guidance, and replacement limitations for engineers evaluating the MIC5800YM-TR in embedded control and electromechanical designs.
MK2771-16R - Specifications, Alternatives and Buying Guide
The MK2771-16R is an electronic component whose verified manufacturer identification, package, electrical ratings, pinout, and lifecycle status were not available in the supplied source records on October 29, 2026. The available retrieval targeted the MPN, datasheet, specifications, and price, but it timed out before returning a component record or manufacturer URL. Consequently, this page does not assign unverified functions, ratings, or equivalent parts to the MK2771-16R. It instead defines the documentation and sourcing evidence still required for engineering release. A component datasheet is the primary technical record for an integrated circuit or discrete semiconductor. It defines the manufacturer's recommended operating conditions, absolute maximum ratings, electrical characteristics, package dimensions, terminal assignments, and application information. Without that evidence, the MK2771-16R cannot be responsibly classified as a controller, interface device, power device, memory, or another specific component type. Engineers should obtain the manufacturer datasheet before selecting this MPN for a new design. The verified retrieval establishes only the exact orderable MPN, MK2771-16R, and the search context used to locate its documentation. It does not establish a manufacturer, package, pin count, operating voltage, current rating, frequency, temperature range, or compliance status. The suffix “-16R” is therefore treated only as part of the supplied MPN and is not interpreted as temperature grade, package code, revision, or reel configuration without documentary evidence. Pin-compatible replacement analysis also requires verified package dimensions, terminal numbering, exposed-pad details, and electrical limits for both the original part and each candidate. The targeted substitute search returned no records for MK2771-16R, so no drop-in alternatives are asserted. Adding a candidate merely because it resembles the MPN would create a risk of incorrect soldering, missing thermal connections, different signal limits, or incompatible logic thresholds. Potential engineering uses cannot be responsibly assigned from the current evidence because no verified function or application list is available. Before using the MK2771-16R, engineers should compare its manufacturer datasheet against the required interface, supply, timing, environmental, and qualification constraints of the target circuit. For prototype work, the exact manufacturer, package marking, and ordering suffix should be confirmed with the supplier rather than inferred from the visible part number. The practical design gate is therefore documentation-based: obtain the genuine manufacturer datasheet, verify the complete pinout and maximum ratings, and review the recommended application circuit. Any substitution must then be checked for the same footprint, pin-to-pin terminal assignments, equivalent electrical limits, and appropriate lifecycle availability. This approach prevents an unverified alternative from creating a board respin or field failure. This page consolidates the available MPN, source-retrieval status, specification gaps, sourcing questions, and strict drop-in replacement criteria. It adds practical decision guidance beyond the timed-out search result while clearly separating verified information from unknown fields. No fabricated datasheet number, package, pinout, electrical rating, stock condition, price, lead time, or equivalent MPN is presented.

MP2736DQG-LF-P - 450mΩ Dual SPDT Analog Switch | MPS
The Monolithic Power Systems MP2736DQG-LF-P is a low-voltage, 450 mΩ dual single-pole double-throw monolithic CMOS analog switch operating from 1.65 V to 5.5 V in a 10-QFN package measuring 1.4 mm by 1.8 mm. It provides two 2:1 switch circuits with bidirectional signal paths, low-power operation, fast switching, and glitch-free behavior. An analog switch is an integrated semiconductor device that routes signals between circuit nodes under digital control. The SPDT topology connects one common terminal to one of two selectable terminals, allowing one signal source to be steered between two destinations. A dual SPDT switch contains two independently controlled 2:1 paths. Within the device hierarchy, the MP2736DQG-LF-P is an analog switch IC, a member of the broader interface IC category used for signal routing and multiplexing. Key features include a low on-resistance of 450 mΩ, a single-supply operating range of 1.65 V to 5.5 V, and a specified operating temperature range from -40°C to +85°C. The MP2736 family combines low power consumption, high switching speed, low on-resistance, and a small package. Its two switching circuits and common enable architecture suit compact portable and battery-powered equipment where PCB area and supply current are important constraints. The MP2736 is implemented as a monolithic CMOS analog switch, allowing low-voltage operation and efficient signal routing. Switching times of 35 ns and 36 ns are specified in the verified product information, supporting applications that cannot tolerate lengthy transition intervals. The available bandwidth reaches 50 MHz, while the 130 pF value identifies the relevant capacitance specification from the supplied source data. Because the switch is bidirectional, it can route signals in either direction when the electrical operating conditions remain within the device limits. Typical uses include battery-powered audio routing, portable test and measurement interfaces, communication-signal multiplexing, sensor-path selection, and general analog signal switching. The 10-QFN package provides a practical footprint for dense portable systems, while the 1.65 V to 5.5 V range covers common low-voltage rails. In each case, the design must account for signal amplitude, switching duration, off-state behavior, and the exact enable polarity and timing required by the application. A key design consideration is that low on-resistance does not eliminate all analog-switch limitations. Board leakage, connector resistance, and trace resistance can dominate a 450 mΩ path, while capacitive loading can influence switching performance. Designers should minimize sensitive traces, use a continuous ground reference, and verify signal integrity with the actual source impedance, load, supply voltage, and enable sequence before production release. This page consolidates verified manufacturer and distributor information, parameter comparisons, procurement context, and practical design guidance for engineers evaluating the MP2736DQG-LF-P as a low-voltage, low-resistance dual SPDT analog switch.
MP2736DQG-LF-Z - 0.45 Ohm Dual SPDT Analog Switch | MPS
The Monolithic Power Systems MP2736DQG-LF-Z is a low-voltage, low-on-resistance, dual single-pole double-throw (SPDT) monolithic CMOS analog switch IC with a 450 mOhm on-resistance and a 10-QFN package measuring 1.4 mm by 1.8 mm. The device operates from 1.65 V to 5.5 V and is designed for high-performance switching of analog signals in portable, battery-powered, and other compact electronic systems. The MP2736 combines two independently controlled SPDT switches in one IC. Its monolithic CMOS construction supports low power consumption, high switching speed, low on-resistance, and small package size. The manufacturer identifies the MP2735/MP2736 family as suitable for portable and battery-power applications where analog signal routing must be compact and power efficient. The MP2736 uses an EN control input. According to the manufacturer datasheet information, all switches are placed in a high-impedance state when EN is high. This global enable behavior provides a defined off condition for both SPDT channels and can simplify system-level control when analog paths must be isolated. The dual SPDT arrangement supports selecting one of two signal sources per channel or routing a signal to one of two destinations, depending on the surrounding circuit topology. The 450 mOhm on-resistance specification is the key low-voltage analog switching parameter identified in the verified distributor listings. Lower on-resistance helps reduce signal attenuation and improves source-to-load drive capability, while the 1.65 V to 5.5 V operating range allows operation from a single low-voltage supply. The 10-QFN package is particularly useful in portable equipment where board area is constrained. The -Z ordering suffix is supplied in tape-and-reel packaging according to distributor product information. Typical applications include battery-powered sensor interfaces, portable measurement systems, audio routing, communication equipment, and compact analog signal-conditioning circuits. The EN pin can be used for power-down or signal-isolation control. Designers should verify the exact pin names, logic levels, switch configuration, and timing behavior against the MP2736 datasheet before finalizing a PCB layout. This page combines the verified manufacturer and distributor information with practical selection guidance, package details, and design considerations. It is intended to help engineers identify whether the MP2736DQG-LF-Z is suitable for a low-voltage analog-routing design and to distinguish it from unrelated switch functions or package-incompatible alternatives.
MPC506AP - 16:1, ±15V Analog Multiplexer | Texas Instruments
The Texas Instruments MPC506AP is a 16:1, one-channel CMOS analog multiplexer with a 16 V dual-supply range, 1.5 kOhm on-resistance, and a 28-PDIP package. According to the verified distributor listing, it is designed for single-ended routing of up to 16 analog inputs while providing input overvoltage protection. The mux is suitable when a system must select among multiple sensor, measurement, control, or instrumentation signals. 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.
MPC506APG4 - 16:1 CMOS Analog Multiplexer | Texas Instruments
The Texas Instruments MPC506APG4 is a single-ended 16-channel or differential 8-channel CMOS analog multiplexer with a typical on-resistance of 1.5 kOhm, housed in a 28-pin PDIP package. It also provides analog overvoltage protection, no channel interaction during an overvoltage condition, and break-before-make switching. These characteristics make it suitable for routing multiple analog inputs through a shared analog-to-digital converter or measurement front end when channel isolation, predictable switching behavior, and limited fault energy are important. An analog multiplexer is a switching interface that connects one of several signal inputs to a common output. The MPC506APG4 can operate as a 16:1 single-ended multiplexer or as an 8:1 differential multiplexer. Within the broader semiconductor hierarchy, it is an analog switch and multiplexer, an interface IC, and ultimately a power-management-independent signal-routing device. The CMOS implementation supports bidirectional signal routing rather than restricting the device to a one-way digital path. Verified device features include analog overvoltage protection, suppression of channel interaction during overvoltage, and break-before-make operation. Break-before-make switching prevents the previous channel and the next channel from conducting simultaneously during a transition, which reduces transients and crosstalk at the multiplexer output. The published analog signal range extends to plus or minus 15 V, while standby power is specified as 7.5 mW typical. The 1.5 kOhm typical on-resistance identifies the part as a precision analog multiplexer rather than a low-resistance power switch. The MPC506APG4 combines a 16-channel single-ended configuration with an 8-channel differential configuration. This dual organization allows one device to serve designs where each measurement is referenced to a common return, as well as designs that require paired positive and negative inputs. Differential operation can reduce sensitivity to common-mode voltage and ground offsets when the source circuitry and downstream converter support balanced signaling. Selection between the two operating modes is governed by the system wiring and the control logic presented to the device. Typical uses include multiplexed data acquisition, automated test equipment, instrumentation panels, industrial monitoring, process-control measurement systems, and communication routing boards. The overvoltage-protection feature is particularly relevant when external transducers or field wiring may present a fault voltage. In such systems, a protected multiplexer can limit fault propagation to downstream circuitry while its break-before-make behavior helps isolate channels during selection changes. When designing around this device, verify the complete switch-control sequence and allow adequate settling time after each address change before sampling the multiplexed output. External protection, clamping, and filtering may still be required for long field-wiring runs. Because the provided distributor listing identifies the package as a 28-pin PDIP, the device should be treated as a through-hole component and checked against PCB drilling, connector spacing, and assembly thermal requirements before a production release. This page consolidates distributor availability information, verified device features, package details, and engineering guidance into one implementation-focused reference. It also distinguishes the information confirmed by the retrieved sources from electrical details that still require confirmation in the complete manufacturer datasheet before precision design sign-off.
MPC506AU - 16:1, 16V Analog Multiplexer | Texas Instruments
The Texas Instruments MPC506AU is a single-circuit, 16:1 CMOS analog multiplexer with a 16 V power supply, 1.5 kOhm on-state resistance, and 28-pin SOIC (DW) package. Designed by Texas Instruments as the MPC506A general-purpose single-ended multiplexer, it routes one of 16 analog inputs to one output while providing analog overvoltage protection, break-before-make switching, and no channel interaction during overvoltage. The device is identified by DigiKey as a 16:1 analog switch IC with one circuit and 1.5 kOhm resistance. An analog multiplexer is a semiconductor switching network that connects one selected input channel to a shared output. A single-ended analog multiplexer belongs to the broader analog switch hierarchy and connects to analog front ends, data acquisition systems, test equipment, industrial control, and instrumentation. The MPC506AU uses digital select and enable logic to control its analog signal path, allowing one measurement amplifier, converter, or input instrument to inspect multiple sensor or source channels. Verified features include a ±15 V analog signal range, analog overvoltage protection, no channel interaction during overvoltage, break-before-make switching, and 7.5 mW typical standby power. The protection circuitry is intended to preserve signal fidelity when an analog input exceeds either power-supply voltage. Texas Instruments describes the MPC506A as a 16-channel single-ended multiplexer; the separately described MPC507A is an 8-channel differential multiplexer and is therefore not a functional drop-in substitute. The 28-pin DW SOIC package supports surface-mount assembly, while its digital controls allow a controller to select channels in a sequential measurement system. The verified part detail lists a -40°C to 85°C operating-temperature range and a 16 V supply condition. Other switching timing, capacitance, leakage, channel-count logic, and absolute-maximum values are not present in the supplied result excerpts and must be checked in the manufacturer datasheet before final design release. Typical uses include multiplexed sensor acquisition, automated test systems, programmable instrumentation, industrial measurement, and signal routing where multiple analog sources share one downstream converter. The key design consideration is preserving accuracy during channel transitions. Use the specified break-before-make behavior, observe address and enable setup timing from the datasheet, and account for the 1.5 kOhm on-resistance when calculating source-load attenuation or input-current requirements. This product record combines the verified manufacturer and distributor descriptions with practical routing, switching, and signal-integrity guidance. It also separates true pin-compatible alternatives from related multiplexers that differ functionally, preventing a package-only match from being presented as an engineering drop-in replacement.
MPC506AU/1K - 16:1 Analog Multiplexer | Texas Instruments
The Texas Instruments MPC506AU/1K is a 16-channel, single-ended, 16:1 CMOS analog multiplexer with a 1.5 kΩ on-resistance, analog signal range of ±15 V, and 28-pin SOIC package. It also provides analog overvoltage protection, break-before-make switching, and a true second source. An analog multiplexer is a switching device that routes one of several analog inputs to a common output. The broader hierarchy is analog multiplexer → analog switch → signal-routing IC → semiconductor. This distinction is important because the MPC506AU/1K supports multiple single-ended channels, whereas a multiplexer with fewer channels or a differential architecture may not be interchangeable without changing the system architecture. The most prominent device features are 16:1 channel selection, a 1.5 kΩ on-resistance, a ±15 V analog signal range, and analog overvoltage protection. The overvoltage-protection architecture allows an analog input to exceed a supply voltage without damaging the device or disturbing other channels. Break-before-make switching reduces the interval in which two channels are connected together, helping prevent unintended signal transfer during address transitions. Internally, the device uses CMOS switching structures controlled by digital select and enable logic. Its standby power consumption is listed as 7.5 mW typical in the available MPC506 documentation. The protected signal path is intended to preserve signal fidelity when an external node experiences excessive voltage, while the 16-channel arrangement reduces the number of external routing switches required in measurement and control systems. Typical applications include automated test equipment, data acquisition systems, instrumentation, industrial control, signal routing, and analog measurement front ends. The 16 selectable inputs allow one measurement chain to interrogate multiple sensors or conditioned analog sources sequentially. Designers must still account for channel resistance, switching transients, input loading, address timing, and the limits of the protected input network when establishing accuracy and bandwidth targets. A principal design consideration is off-state isolation. A multiplexer does not create an ideal disconnect, so source impedance, capacitance, leakage, crosstalk, and the characteristics of the selected channel can influence settling time and measurement accuracy. The source impedance connected to each input should therefore be evaluated together with the mux resistance rather than in isolation. This page combines verified manufacturer and distributor information, complete pinout availability status, practical application guidance, and a strict drop-in assessment. It distinguishes electrically compatible ordering variants from unsupported cross-package or redesign-only alternatives so engineers can make a defensible replacement decision.
MPC506AUG4 - 16:1 Analog Multiplexer | Texas Instruments
The Texas Instruments MPC506AUG4 is a 16-channel, single-ended CMOS analog multiplexer with a 16:1 configuration, 1.5 kOhm on-resistance, and a 28-pin SOIC package. Its headline characteristics include analog overvoltage protection to 70 VPP, no channel interaction during an overvoltage condition, break-before-make switching, an analog signal range of ±15 V, and 7.5 mW typical standby power. An analog multiplexer is an interface IC that routes one of several analog input channels to a common output. It sits within the hierarchy of analog switch, multiplexer, interface IC, and semiconductor. A single-ended 16:1 device uses one signal conductor per channel, making it suitable for systems that select among multiple voltage-based sensor, measurement, or control signals. The MPC506AUG4 provides that selection function while adding protection against excessive analog input voltage. The 70 VPP analog overvoltage protection is the part's most distinctive feature. According to the Texas Instruments MPC506A data sheet, input signals may exceed the power-supply voltages without damaging the multiplexer or disturbing other channels. This allows the selected channel to handle overvoltage conditions while the device maintains signal fidelity. Break-before-make switching provides an additional transition-control characteristic during channel changes. The MPC506AUG4 is identified as a 16-channel single-ended multiplexer, while the broader MPC506 family also includes an 8-channel differential multiplexer. Its 1.5 kOhm on-resistance is suitable for moderate-impedance analog networks, and the ±15 V specified analog signal range supports applications using bipolar analog levels. The 28-pin SOIC package supports conventional surface-mount PCB assembly. Typical uses include multichannel data acquisition, automated test equipment, instrumentation, industrial control, and signal routing where multiple analog sources must share one downstream converter or amplifier. Its input-overvoltage tolerance is particularly useful when long external lines or field-connected sources can present transients above the local supply rails. When designing around the MPC506AUG4, verify the absolute maximum analog input voltage, supply sequence, channel-switching behavior, and external source impedance. Because the verified product data does not provide a complete pin map, channel conductor resistance, charge injection, or off-state leakage, those values must be confirmed in the manufacturer data sheet before a new layout is released. This product record consolidates the verified distributor and manufacturer information into an engineering-focused view of protection, switching, packaging, procurement, and design constraints. It also clearly separates confirmed parameters from values that still require datasheet verification, helping engineers evaluate the MPC506AUG4 without overlooking analog protection or PCB-compatibility requirements.
MPC507AP - 8:1 Differential Analog Mux | Texas Instruments
The Texas Instruments MPC507AP is a 16 V, 8:1 differential, single-channel CMOS analog multiplexer packaged in a 28-pin PDIP. The verified product information identifies one multiplexed signal path, two control circuits, 1.5 kOhm on-state resistance, analog overvoltage protection, and a typical standby power dissipation of 7.5 mW. It supports ±15 V analog signals and uses break-before-make switching with no channel interaction during overvoltage. An analog multiplexer is an interface IC that routes one of several physical inputs to a shared output according to digital address and enable signals. In differential operation, the MPC507AP selects one of eight paired inputs, reducing the number of downstream converters or signal-processing channels. Its hierarchy is analog multiplexer → multiplexer/demultiplexer → interface IC → semiconductor. Differential multiplexing is useful where two coupled signal lines must be selected together to preserve common-mode relationships. The principal features include 8:1 differential operation, a 16 V rated signal range, 1.5 kOhm on-state resistance, and analog input overvoltage protection. According to the available manufacturer-family data, analog inputs may exceed a supply voltage without damaging the device or disturbing other channels. Break-before-make switching prevents two channels from conducting together during address transitions, an important consideration when the selected source can produce significant voltage. The MPC507AP uses separate address and enable logic to control its analog routing. Digital control signals determine which differential pair connects to the common output, while the enable function places the device into a low-power state when it is not required. The verified search results also identify approximately 700 uA standby current and ±5 V to ±22 V supply-related information in distributor documentation, but the complete electrical limits must be confirmed in the manufacturer datasheet before final design release. Typical uses include multi-channel instrumentation, differential sensor acquisition, automated test systems, data acquisition interfaces, and industrial control modules. The part is most appropriate when eight differential sources must reach one downstream signal chain and when a wired-through-hole 28-pin package is acceptable. The tradeoff is its legacy PDIP format and analog-switch resistance, which can matter in precision, high-speed, or space-constrained systems. PCB layout should keep the mux output path short and provide a stable ground reference. Decoupling and protection requirements must follow the manufacturer datasheet, while unused digital inputs should be driven to defined levels rather than left floating. This page combines verified product information, distributor availability references, package details, and engineering guidance without inventing undocumented electrical limits.
MPC507APG4 - 8-Channel Differential Analog Multiplexer | TI
The Texas Instruments MPC507APG4 is a dual 8:1 CMOS analog multiplexer with a maximum on-state resistance of 1.5 kOhm, switching times of 200 ns Ton and 250 ns Toff, and operation from dual +5 V to ±22 V supplies. The device is packaged in a 28-pin plastic dual in-line package (PDIP). An analog multiplexer is an interface IC that connects multiple analog inputs to a shared output under digital control. A differential multiplexer can route paired input signals and reduce common-mode interference, while a single-ended multiplexer selects one signal relative to ground. In the IC hierarchy, the MPC507APG4 is a CMOS analog switch, analog multiplexer, interface IC, and semiconductor designed to route instrumentation and control signals efficiently. Key features include analog overvoltage protection, no channel interaction during overvoltage, and break-before-make switching. The supported analog signal range reaches ±15 V, while standby power is 7.5 mW typical. The MPC507A family provides 16 single-ended channels or eight differential channels, making it useful for multichannel measurement, test, instrumentation, and signal-routing systems. The device uses separate digital address and enable controls to select one of eight differential channels. Because it is a CMOS implementation, low switching time and low standby power support acquisition systems that repeatedly change measurement paths. The dual-supply architecture also allows bipolar signals to be routed without a single-supply level-shifting arrangement. Typical applications include automated test equipment, data-acquisition systems, process-control instrumentation, multiplexed sensor interfaces, and laboratory measurement systems. Engineers should account for the relatively high 1.5 kOhm on-state resistance when interpreting source impedance, and should verify that every selected input remains within the device's absolute maximum ratings. Designers should preserve break-before-make timing and route sensitive analog inputs away from high-impedance control nets. Input filtering may be required when leakage, switching transients, or overvoltage events could affect the measured signal. The 28-pin PDIP also requires adequate spacing between adjacent boards and provides straightforward through-hole assembly for legacy and industrial equipment. This page consolidates verified manufacturer and distributor details, compares directly related MPC507 variants, and adds practical guidance on switching, signal integrity, protection, and procurement for engineers evaluating this legacy analog multiplexer.

Typical switching times are 200 ns turn-on and 250 ns turn-off. An analog multiplexer is a switching IC that routes one of several input signals to a shared output while preserving the integrity of the selected waveform. A differential 8:1 mux combines that function with paired signal paths, allowing two related analog inputs to be selected together. In the electronics hierarchy, the MPC507 belongs to the analog switch and multiplexer class, then to interface ICs and semiconductors. This makes it useful where multiple sensors, measurement inputs, or control lines must share a limited number of converter and amplifier inputs. The principal benefits of the MPC507AU/1K include protected analog inputs, a ±15 V signal range, dual 1.5 kOhm switch sections, and operating temperatures from -40°C to +85°C. The protection circuitry allows an analog input to exceed a supply voltage without damaging the device or disturbing other channels, according to the Texas Instruments MPC507 product information. This feature is valuable in industrial systems where transients or misconnection are possible. Technically, the device uses CMOS analog switching to support the stated ±15 V range and sub-microsecond transitions. Break-before-make operation limits the interval in which old and new channels overlap, while true second-source behavior supports applications requiring duplicated paths. The 28-pin SOIC package is a surface-mount, gull-wing package suitable for conventional PCB assembly and automated production. Typical applications include multiplexed data acquisition, industrial sensor routing, automated test equipment, analog signal instrumentation, and multi-channel measurement systems. In these systems, the MPC507 reduces the number of external analog front-end channels while preserving selectable overvoltage-protected inputs. When designing around this multiplexer, verify the actual supply voltages, input range, channel timing, and leakage requirements against the manufacturer datasheet. Keep high-impedance routing short, provide adequate return paths, and account for source impedance when calculating settling behavior. The 1.5 kOhm maximum on-state resistance can create attenuation and channel-to-channel gain variation if the selected source impedance is high. This page consolidates the verified manufacturer and distributor information, explicit drop-in cross-reference results, package details, commercial availability links, and practical selection guidance into one engineering-focused reference for the MPC507AU/1K.
MPC507AUG4 - 8:1 Differential Analog Multiplexer | Texas Instruments
The Texas Instruments MPC507AUG4 is a 16-V, 8:1 differential analog multiplexer packaged in a 28-pin SOIC. It routes eight differential analog input channels to one output pair, provides analog overvoltage protection of 70 VPP, and maintains channel isolation during overvoltage conditions. The device operates from dual positive and negative supplies, supports analog signals from -15 V to +15 V, and features break-before-make switching. An analog multiplexer is a switching interface that connects one of several analog inputs to a shared output. The MPC507AUG4 operates in differential mode, using eight differential channel pairs rather than eight single-ended sources. This arrangement is useful when a measurement system must preserve the relationship between a positive and negative signal while selecting among multiple sensors, instrumentation inputs, or test points. In the component hierarchy, it is an analog switch IC, analog multiplexer, interface IC, and ultimately a semiconductor. Key features include 70 VPP analog overvoltage protection, no channel interaction during overvoltage, break-before-make switching to minimize switch overlap, a -15 V to +15 V analog signal range, and 7.5 mW typical standby power. The 1.5 kOhm on-resistance listed by DigiKey identifies the switching element resistance used when selecting a channel. The overvoltage protection is particularly important in industrial and test systems where transient or unexpected input amplitudes can otherwise damage the signal path or disturb unselected channels. Typical uses include multiplexed data acquisition, automated test equipment, instrumentation front ends, industrial sensor selection, and differential signal routing. Because the MPC507AUG4 accepts a wide bipolar analog range, it can reduce the need for separate upstream attenuation when inputs remain within the specified analog signal range. The 28-pin SOIC package is a surface-mount package suitable for conventional PCB assembly and automated production. The key design consideration is that overvoltage protection does not replace correct supply sequencing or input-range validation. Keep all inputs within the stated analog range unless the system intentionally exercises the protection function, and observe the manufacturer timing and logic-level requirements for address and enable control. Verify the exact pin assignments in the manufacturer datasheet before layout because the supplied web results describe the device but do not publish a complete numbered pin table. This page combines verified distributor specifications, manufacturer product information, cross-reference results, and practical selection guidance. It also distinguishes true pin-compatible drop-in options from functional equivalents that differ in channel architecture or pin assignment, helping engineers avoid PCB rework.
MPC508AP - 8:1 16V Analog Multiplexer | Texas Instruments
The Texas Instruments MPC508AP is a 16-V, 8:1, single-ended, one-channel CMOS analog multiplexer in a 16-pin PDIP package. It provides eight analog inputs, break-before-make switching, and input overvoltage protection rated at 70 Vpp. According to the Texas Instruments product page, the device is intended for selecting one of eight single-ended signals while protecting the signal path during fault conditions. An analog multiplexer is an analog switch that routes one of several input signals to a common output. The MPC508AP belongs to the analog switch and multiplexer hierarchy, which supports signal acquisition, test systems, instrumentation, data conversion, and channel selection. Its 8:1 configuration reduces the number of external connections required when multiple sensors or measurement channels must share one downstream converter. The principal verified features include an 8-channel single-ended input arrangement, a ±15 V analog signal range, 70 Vpp input overvoltage protection, break-before-make switching, and typical standby power of 7.5 mW. The overvoltage-protection architecture allows analog inputs to exceed the supply rails without disturbing other channels, a useful property in systems where a fault or transients may occur on an external signal line. The DIP-16 package also supports through-hole prototyping and replacement in designs designed around the original footprint. The MPC508AP is distinct from a digital multiplexer because its switch path is intended to preserve analog signal fidelity rather than implement logic-level selection. Its CMOS implementation, protected inputs, and multiple analog channels make it suitable for data-acquisition front ends, automated test equipment, instrumentation, and signal-routing systems. The exact dynamic resistance, channel capacitance, leakage, propagation delay, supply-current, and logic-threshold values are not present in the supplied verified data and must be confirmed from the manufacturer datasheet before final design release. A typical circuit places the selected input at the multiplexer output and connects that output to an ADC, amplifier, or measurement instrument. The system should provide suitable supply rails, observe the control-signal sequencing requirements, and account for analog input limits and off-channel behavior. The DIP package is mechanically straightforward, but users should follow the manufacturer’s pin and layout guidance rather than infer connections from generic DIP conventions. This product data combines the verified Texas Instruments product identity, distributor listing information, datasheet references, and application-oriented guidance. It intentionally distinguishes documented parameters from unavailable technical fields rather than estimating them, helping engineers evaluate the MPC508AP for new designs and replacement planning.
MPC508AU/1K - 8:1 16V Analog Multiplexer | Texas Instruments
The Texas Instruments MPC508AU/1K is a 16-V, 8:1, single-ended, one-channel CMOS analog multiplexer packaged in a 16-pin SOIC. It routes one of eight analog inputs to a common output, provides 1.5 kOhm nominal on-resistance, and supports an analog signal range of ±15 V. The device also includes input overvoltage protection rated at 70 V peak-to-peak, break-before-make switching, no channel interaction during an overvoltage condition, and a true second source. Its operating temperature range is -40°C to +85°C. An analog multiplexer is a switching interface that connects multiple analog signals to one input on an ADC, data converter, measurement instrument, or control system. The MPC508A belongs to the broader CMOS analog-switch and multiplexer hierarchy within interface ICs. In its 8:1 single-ended configuration, three address lines select one of eight input channels, reducing the number of external converter inputs required in multichannel measurement equipment. The principal feature is its 70-V peak-to-peak analog overvoltage protection. This allows an input to exceed the normal ±15 V signal range without damaging the multiplexer or disturbing other channels. Break-before-make switching further improves channel isolation by preventing two channels from being connected together during address transitions. These features are useful when external equipment, fault conditions, or long signal lines can place unexpected voltage on an analog input. The MPC508AU/1K is fabricated as a CMOS analog multiplexer and operates from a 16-V supply. Its stated standby power is 7.5 mW typical, while its nominal on-resistance is 1.5 kOhm. The 16-SOIC package measures approximately 0.295 inches, or 7.50 mm, in width. The /1K ordering code is supplied in tape-and-reel form for automated manufacturing, although the provided data does not state the reel quantity. Typical uses include multiplexed data acquisition, instrumentation, industrial control, test and measurement, and signal-routing circuits where one ADC input can serve several analog sensors. The protected inputs are particularly relevant when connected to external equipment where transient or sustained overvoltage is possible. Engineers should still validate the complete signal path against the absolute maximum ratings because overvoltage protection does not remove the need for suitable source impedance, scaling, and external energy limitation. When laying out a design, route the selected analog output as a short, guarded trace and place the multiplexer close to the ADC or measurement front end. Keep digital address traces away from the analog input and output paths, use a common ground reference, and avoid unnecessary stubs. If source impedance or settling time is important, verify the complete acquisition system rather than relying only on the nominal 1.5-kOhm on-resistance. This page consolidates verified manufacturer and distributor information, practical application guidance, parameter comparisons, and sourcing details. It also clearly identifies where package, pinout, pricing-tier, and drop-in replacement data were not supplied rather than inventing engineering values.
MPC508AUG4 - 8:1 ±15V Overvoltage-Protected Analog MUX | Texas Instruments
Texas Instruments MPC508AUG4 is an 8:1 CMOS analog multiplexer with single-ended 8-channel and differential 4-channel configurations, ±15 V analog signal capability, 1.5 kOhm on-resistance, and a 16-pin SOIC package. It also provides 70 Vpp analog overvoltage protection, break-before-make switching, and no channel interaction during an overvoltage event. These characteristics position it as an interface IC for analog switching, signal routing, test and measurement, data acquisition, industrial control, and instrumentation systems. An analog multiplexer is a semiconductor switching network that connects one of several input terminals to a shared output. In the broad electronics hierarchy, it belongs to analog switches and multiplexers, which are interface ICs used to route signals among sensors, amplifiers, converters, and test equipment. The MPC508AUG4 can support eight single-ended channels or four differential channels, making it useful where multiple inputs must be measured through a common signal chain without duplicating amplifiers or converters. The principal features include 70 Vpp overvoltage protection, a stated analog signal range of ±15 V, 1.5 kOhm on-resistance, and break-before-make operation. The protection circuit allows an analog input to exceed a supply voltage without damaging the device or disturbing the signal path of other channels. Standby power is specified as 7.5 mW typical, making the part suitable for multiplexed systems that disable the analog path during inactive intervals. The device uses CMOS switching elements with separate control logic for selecting the single-ended or differential operating mode. Break-before-make behavior prevents two channels from being connected simultaneously during a transition, reducing signal contention and preserving channel isolation. The overvoltage protection is particularly relevant in external analog systems where transients or wiring errors may exceed the nominal rail-to-rail operating range. Typical uses include multiplexed data acquisition, automated test equipment, industrial process monitoring, instrumentation, and communication or control boards with multiple analog inputs. In each case, the shared output can feed a downstream amplifier, sample-and-hold circuit, or ADC, while the multiplexer reduces the number of analog front-end channels required. Differential operation is useful when the source signals require common-mode rejection or when the selected pair must be treated as one differential measurement. Designers should verify address-decoder transitions, supply sequencing, input overvoltage conditions, and the intended single-ended or differential wiring against the manufacturer datasheet. The 16-pin SOIC footprint simplifies assembly, but signal-path layout and grounding remain important because high-impedance multiplexed nodes can couple noise from adjacent digital control traces. This page combines verified manufacturer and distributor information with same-package alternatives, a practical comparison table, and application-specific design guidance. It also separates documented electrical values from parameters that require confirmation from the datasheet, helping engineers identify what is known and what must be checked before layout or purchasing decisions.
