The Analog Devices MAX350EWN+ is a serially controlled, low-voltage CMOS analog multiplexer configured as two independent 4:1 switches in an 18-pin wide SOIC package. It operates from 2.7 V to 16 V and provides a maximum on-resistance of 100 ohm, with channel-to-channel matching limited to 16 ohm and resistance variation across the specified signal range limited to 10 ohm. The MAX350EWN+ conducts signal equally well in either direction, allowing it to route analog inputs or outputs through a serial interface. An analog multiplexer is a semiconductor that connects one signal path to one of several channels through controlled switches. The MAX350 family extends this category to the hierarchy of analog switch, multiplexer, routing IC, and signal-management semiconductor. Its 4:1 dual configuration provides two separately selectable channel groups, making it suitable for channel-scanning systems where multiple sensors, measurement inputs, or controlled outputs share a common signal chain. Key features include serial control, bidirectional signal conduction, low-voltage CMOS operation, and tightly matched switch resistance. The 100 ohm maximum on-resistance limits signal attenuation, while the 16 ohm maximum channel-to-channel match improves consistency when comparing readings across different channels. Its 18-pin wide SOIC package also provides a practical surface-mount footprint for industrial and instrumentation designs. The device uses a serial interface to select channels and control the multiplexers, reducing the number of package pins needed compared with a parallel-control multiplexer. This architecture is valuable in systems that route several slow or moderate-bandwidth analog signals, particularly when the microcontroller has limited general-purpose input/output capacity. Typical applications include multimeter and laboratory input switching, automated test equipment, data-acquisition modules, sensor-channel multiplexing, and control of multiple analog signal paths. The MAX350EWN+ is appropriate when bidirectional analog routing and matched resistance are more important than ultra-low on-resistance or high-speed video multiplexing. When laying out the circuit, keep analog traces short and connect the device to a stable low-noise supply. Confirm the serial interface levels and logic thresholds against the system controller, and verify that every switched signal remains within the specified analog input range. Check the full on-resistance and off-isolation characteristics in the manufacturer datasheet when the signal source is high impedance.
MAX354EWE+ 8:1 Fault-Protected Analog Multiplexer | Analog Devices
The Analog Devices MAX354EWE+ is a single 8:1 analog multiplexer with a 350 ohm on-resistance, fault protection to 40 V beyond the supply rails, and a 16-pin SOIC package. It routes one of eight single-ended analog inputs to a common output while protecting sensitive downstream circuitry during power-up, power-down, and fault conditions. An analog multiplexer is an interface IC that connects multiple signal paths to a shared processing or measurement resource. The MAX354 belongs to the broader switch and multiplexer hierarchy, where multiplexing reduces the number of input channels, converters, amplifiers, or external connectors required by an electronic system. Its fault-protected architecture is especially useful when external signals can exceed the nominal supply range during startup or abnormal operating conditions. The MAX354EWE+ provides eight channels, a 350 ohm on-resistance, and protection against overvoltage up to 40 V beyond the supply rails. These characteristics make the device relevant to data acquisition, instrumentation, test systems, industrial control, and battery-powered equipment. The MAX354/MAX355 family uses a series N-channel, P-channel, N-channel structure that isolates protected downstream components from excessive input voltage. The device is specified as a single-ended multiplexer in a 16-SOIC surface-mount package. Its industrial temperature grade suits equipment expected to operate across demanding environmental conditions. Because on-resistance and protection behavior influence signal fidelity and system reliability, designers should account for the complete source impedance, selected channel, supply state, and external signal amplitude rather than treating the switch as an ideal conductor. Typical uses include eight-channel sensor selection, industrial measurement front ends, automated test equipment, and embedded control systems that need to share an analog-to-digital converter or signal-conditioning channel. In these systems, the multiplexer reduces channel count while the fault-protected structure provides additional tolerance for externally driven signals. The final input range must remain compatible with the complete signal chain and device operating limits. A key design consideration is the relationship between the multiplexer, the protected signal source, and downstream circuitry. Keep sensitive return paths compact, observe the manufacturer’s pin configuration when assigning inputs and enables, and evaluate the switch resistance in the source impedance of the selected channel. The 350 ohm on-resistance is especially important for high-impedance sensors and low-amplitude measurements. This product page combines the manufacturer’s multiplex function, protection characteristics, package details, application analysis, and parameter-level comparison. It also distinguishes device-family options from true pin-compatible drop-in replacements so that PCB changes are not mistaken for a straightforward substitution.

The MAX392 belongs to the product hierarchy analog switch > multiplexer > interface IC > integrated circuit. Each of the four independent switches in the MAX392 is a single-pole single-throw (SPST) type, so it provides a simple on/off path for analog signals rather than a multi-channel selection function. Key features of the MAX392 family include guaranteed on-resistance matching between channels below 2 Ω, on-resistance flatness over the signal range below 4 Ω, charge injection limited to 4 pC maximum, and improved off leakage of less than 2.5 nA at +85 °C. The part operates from a single +3 V to +15 V supply or from dual bipolar supplies of ±3 V to ±8 V, which allows it to sit alongside both modern low-voltage digital rails and legacy ±5 V analog instrumentation. Internally the device uses MOSFET pass elements switched by CMOS control logic, which keeps the control input compatible with standard TTL and CMOS levels. The very low power consumption of less than 1 µW per switch makes the MAX392 attractive for battery-powered and portable measurement systems where leakage and standby draw dominate the power budget. Electrostatic discharge withstand above 2000 V per Method 3015.7 protects the pins during handling and board assembly. Typical applications include precision test and measurement multiplexing, audio and low-level signal routing in instrumentation, industrial process control module switching, and general-purpose analog signal isolation in data acquisition systems. The quad SPST arrangement lets one package handle four separate signal paths, which reduces both board area and the number of control lines needed. When designing with the MAX392CSE+, pay attention to the negative rail requirement in dual-supply operation and to off-state leakage when the switched node sits near the supply rails. Place the device close to the source and destination so that trace capacitance does not degrade the small charge-injection and switching-glitch performance that make this switch precise in the first place. This page brings together parametric detail, package information, drop-in alternatives and practical design notes so that engineers can qualify the MAX392CSE+ for a precision analog switching requirement without having to piece the data together from several documents.
MAX395EAG+ - 8-Channel Serial SPST Switch | Analog Devices
The Analog Devices MAX395EAG+ is a serially controlled, 8-channel single-pole single-throw analog switch with a maximum on-resistance of 100 ohm, operating from 2.7 V to 16 V and housed in a 24-pin SSOP package. Each of its eight switches can be controlled independently through a serial shift-register interface compatible with SPI, QSPI, and MICROWIRE protocols. An analog switch is a semiconductor device that routes analog or digital signals between circuit nodes under electronic control. The MAX395 combines eight SPST switches with a serial control register, placing it in the hierarchy of analog switch, multiplexer or demultiplexer, interface IC, and semiconductor. It is useful where a microcontroller or test system must address multiple signal paths while minimizing the number of dedicated control pins. The device supports single-supply operation from 2.7 V to 16 V as well as dual-supply operation from ±2.7 V to ±8 V. Its maximum on-resistance is 100 ohm, and switching times are specified at up to 400 ns. Off leakage is 0.1 nA at +25°C and 5 nA at +85°C, helping preserve the integrity of high-impedance analog nodes during disconnected intervals. The internal serial interface shifts command data into the device on the rising edge of SCLK. Data presented at DIN is clocked into the internal shift register, where it controls the states of the eight SPST channels. According to the Analog Devices product page, the MAX395 is electrically equivalent to two MAX391 quad switches and is pin compatible with the MAX335. Typical uses include battery-powered measurement systems, automated test equipment, audio routing, industrial control interfaces, and general-purpose signal multiplexing. The serial interface reduces control-logic wiring, while the eight independently controlled channels provide flexible routing across a compact PCB footprint. Designers should account for the 100 ohm channel resistance when driving the switched nodes, especially with long PCB traces or high-frequency signals. Supply bypassing, grounded return paths, and careful routing of the serial clock and data lines are necessary to limit coupling into the analog channels. The power-up state leaves all switches off and resets the internal shift registers to zero. This page summarizes the device function, operating limits, pin-compatible family relationships, selection trade-offs, and practical integration guidance. It also organizes manufacturer information and technical alternatives to support faster component evaluation and board-level sourcing decisions.
MAX396EQI - 16:1 Precision CMOS Analog Multiplexer | Maxim
The Maxim Integrated (Analog Devices) MAX396EQI is a precision 16-channel/dual 8-channel low-voltage CMOS analog multiplexer housed in a 28-pin PLCC (11.51 x 11.51 mm) package, specified over the industrial -40C to +85C temperature range. The device is built on Maxim's low-voltage CMOS process and integrates a single 16:1 mux (or two 8:1 muxes in parallel mode) with parallel address logic, making it a classic Maxim precision signal-routing building block. It is the original E-series (extended-industrial) part of the MAX396 family. What is an analog multiplexer? An analog multiplexer (mux) is a switch network that routes one of N analog input signals to a single output line under digital control. Muxes are the foundational building block of analog signal chains, sitting between sensors, test points, instrumentation amplifiers, and an ADC. The MAX396EQI specifically belongs to the CMOS analog mux family, characterized by low on-resistance, low leakage, and rail-to-rail analog signal handling - critical for instrumentation and data-acquisition front-ends. Key specifications include 100 ohm maximum on-resistance (matched within 6 ohm between channels), on-resistance flatness of 10 ohm maximum across the specified analog signal range, transition time under 250 ns, and input off-leakage current below 1 nA at +85C. These characteristics make the MAX396EQI well suited for low-distortion multiplexing of precision signals without the channel-mismatch errors that plague generic muxes. The device operates from a single +2.7V to +16V supply (or split +/- supplies), draws a low quiescent current, and provides ESD-rated inputs with TTL/CMOS-compatible address logic. Architecturally it uses charge-pump driven CMOS analog switches that keep the on-resistance flat over the analog signal range - a hallmark of Maxim's precision muxes versus competing JFET or DMOS parts. Typical applications include data-acquisition front-ends, automated test equipment (ATE) signal routing, audio signal routing, instrumentation multiplexing, and process-control analog input boards. Engineers typically pair the MAX396EQI with a precision op-amp buffer and a successive-approximation ADC to build a 16-channel low-noise analog front-end. When designing with the MAX396EQI, observe the absolute maximum analog signal range of V+ and V- rails; exceeding these destroys the switches. Use a low-ESR bypass capacitor of 0.1 uF close to the supply pin and reserve a small RC network on the address lines to suppress digital switching transients that couple into the analog path. Compared with modern pin-compatible successors, the MAX396EQI delivers superior channel matching but consumes more supply current and occupies a larger PLCC footprint than today's TSSOP muxes. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that are not typically consolidated on the manufacturer datasheet, helping engineers select, source, and implement the MAX396EQI more confidently.
MAX458CPL - 8x4 Video Crosspoint Switch | Maxim Integrated
The Maxim Integrated MAX458CPL is an 8x4 video crosspoint switch with four high-speed, buffered output channels, supplied in a 40-pin plastic DIP package. It is designed for routing multiple video input signals to selectable output channels in video distribution, monitoring, and signal-routing systems. The device provides an 8-by-4 crosspoint architecture, with eight input channels and four buffered outputs, allowing several sources to be connected to the appropriate output in a controlled system. A video crosspoint switch is a routing semiconductor used to direct video signals between multiple sources and destinations. In the broader hierarchy, the MAX458CPL belongs to the interface IC family and provides a configurable signal-routing function between video sources and downstream display, processing, or monitoring equipment. Its buffered outputs are intended to preserve signal integrity when signals are routed through the switching matrix. The MAX458CPL is identified in manufacturer-related listings as the MAX458/MAX459 8x4 video crosspoint-switch family with buffers. The MAX458CPL ordering code specifies the commercial temperature grade and a 40-pin DIP package. The product is intended for through-hole PCB assembly rather than surface-mount reflow assembly. Its rectangular DIP outline provides a straightforward connection pattern for equipment with sufficient board space and a suitable through-hole footprint. Typical uses include video surveillance systems, video walls, broadcast and professional video test equipment, monitor routing, and embedded video distribution platforms. The switching matrix allows a controller to select which of eight video inputs feeds one of four buffered outputs. Designers should account for the device's legacy through-hole package, required bypassing, signal routing, grounding, and any video-level or timing constraints defined in the manufacturer datasheet. For a new design, the MAX458CPL is most appropriate when an existing 40-pin DIP footprint and an 8x4 buffered-video architecture are required. For compact or modern equipment, a surface-mount implementation may simplify board layout, but any functional substitute must be verified for pin compatibility, video bandwidth, output drive, supply requirements, control logic, and operating temperature before use. This page summarizes the available product information, package characteristics, functional architecture, sourcing details, and engineering considerations for engineers evaluating the MAX458CPL. Use the manufacturer datasheet and its pin-description table to verify signal assignments, timing, electrical limits, decoupling, and board-layout requirements before releasing a production design.
MAX4850ETE+ - Dual SPDT Over-Rail Analog Switch | Analog Devices
The Analog Devices MAX4850ETE+ is a dual single-pole double-throw analog switch with over-rail signal handling, supplied in a 16-pin TQFN package measuring 3 mm by 3 mm. The verified distributor data identifies the device as a two-channel SPDT switch intended for audio and USB signal-routing applications. Its defining architecture is a pair of independently controlled analog switches that can route a common terminal to one of two switched terminals. An analog switch is a solid-state semiconductor device used to connect or disconnect signal paths under digital control. The SPDT, or single-pole double-throw, topology provides one common terminal and two selectable throws. This makes an SPDT switch useful for selecting between two sources, sharing one output with two paths, or implementing basic routing and isolation functions. MAX4850 belongs to the broader category of interface ICs and analog switch ICs within semiconductor signal-control devices. The MAX4850ETE+ combines two SPDT channels in one compact 16-TQFN package. Its over-rail signal-handling feature is specifically identified in the verified product descriptions. This feature is important in circuits where the switched voltage may extend beyond the device's normal supply-rail limits, although the exact permitted input and supply ranges were not supplied by the verified data and must be confirmed in the manufacturer datasheet before design release. The MAX4850ETE+ is applicable to audio routing, USB signal switching, and other compact interface systems in which two independent selection functions are useful. Its 3 mm by 3 mm TQFN package reduces board area compared with larger switch packages, while exposed-pad construction can improve heat transfer when the device dissipates appreciable power. Exact contact resistance, bandwidth, leakage, channel capacitance, logic thresholds, supply range, and timing values remain unavailable in the supplied records and therefore are not asserted here. Use the MAX4850ETE+ when a design requires dual SPDT switching in the compact 16-TQFN footprint and when its verified over-rail handling characteristics satisfy the signal levels involved. Designers should confirm the complete electrical limits, control-pin truth table, recommended input circuit, and exposed-pad layout against the official datasheet. The verified distributor records support availability inquiries and quote-based purchasing, but they do not provide a numerical price table or confirmed stock quantity. This page distinguishes directly verified facts from missing technical data, connects the device with appropriate audio, USB, routing, and signal-isolation use cases, and explains what engineers must verify before layout. It also records the absence of verified pin-to-pin substitute MPNs instead of presenting speculative cross-brand parts as drop-in replacements.
MAX4851HETE - Quad SPST Over-Rail Switch | Analog Devices
Analog Devices MAX4851HETE is a quad SPST analog switch with over-rail signal handling, a 2 V to 5.5 V supply range, and a 16-pin TQFN package measuring 3 mm by 3 mm. The device provides four independent single-pole, single-throw switch channels, with a stated on resistance of 4.5 ohm, turn-on time of 100 ns, turn-off time of 60 ns, and isolation of 80 dB. Its extended operating range is -40°C to +85°C. An analog switch is a semiconductor device that routes an electrical signal between external terminals under digital control. The SPST designation means each of the four channels has one signal path, while the quad configuration integrates four switches into one package. In the device hierarchy, MAX4851HETE belongs to the analog-switch, interface-IC, and semiconductor categories. This integration allows one controller to manage several independently switched signal lines on a compact circuit board. Over-rail signal handling is the principal functional distinction of the MAX4851 family. This characteristic allows the switched signal to extend beyond the nominal supply-voltage range, which is useful when a source can present a voltage above or below the switch’s normal operating rails. The 2 V to 5.5 V operating range also supports both lower-voltage and conventional 5 V system environments. The compact 16-pin TQFN package reduces PCB area compared with larger switch packages. The MAX4851HETE is designed for signal routing where rapid transitions and channel isolation matter. Its 100 ns turn-on and 60 ns turn-off times provide substantially faster switching than many mechanical relay implementations. The 80 dB isolation specification helps reduce unwanted coupling between channels, while the 4.5 ohm on resistance suits applications where moderate insertion resistance is acceptable. These characteristics position the device between low-cost mechanical relays and more specialized high-performance switch networks. Typical uses include test and measurement signal routing, industrial control interfaces, communication-line switching, instrumentation multiplexing, and embedded systems that must route external signals under firmware control. It can also support over-rail input conditioning when the controlling system has a different voltage domain. The extended -40°C to +85°C range makes it appropriate for industrial equipment where room-temperature commercial components would be insufficient. Designers should verify every signal’s absolute maximum voltage, logic threshold, and permitted over-rail condition before routing it through the switch. Input and ground connections should have low impedance paths, while unused control pins should be driven to a defined state. Because on resistance contributes insertion loss and consumes power, sensitive high-frequency or precision analog paths should be checked for bandwidth and attenuation rather than relying only on nominal transition time. This product page combines the MAX4851 family specifications, package details, sourcing information, and engineering guidance with same-package replacement analysis. It also highlights the practical distinction between fast semiconductor switching, over-rail operation, channel isolation, and the trade-offs associated with the device’s 4.5 ohm on resistance.
MAX4852ETE+T - Dual SPDT Over-Rail Switch | Analog Devices
The Analog Devices MAX4852ETE+T is a dual SPDT analog switch with over-rail signal handling, 4.5 ohm on-resistance, and a 16-pin TQFN package measuring 3 mm by 3 mm. It supports a +2 V to +5.5 V supply range, 1.8 V-compatible logic, 135 MHz -3 dB bandwidth, and signals extending to 5.5 V even beyond the positive supply rail. An analog switch is a semiconductor device that routes electrical signals between circuit nodes under digital control. The MAX4852 belongs to the analog-switch and multiplexer hierarchy, where SPDT means single-pole, double-throw switching. Two independently controlled switches can select one of two signal paths for each pole. Over-rail handling distinguishes this device from conventional rail-to-rail switches by allowing a signal to pass through without distortion when it exceeds the positive supply voltage. The MAX4852 provides low 4.5 ohm on-resistance, 1 microamp low supply current, and a 0.1 ns differential skew specification. Its 135 MHz -3 dB bandwidth supports high-frequency signal routing. The device is also identified as compliant with USB 2.0 full-speed and USB 1.1 signal-switching requirements, making it suitable for low-speed USB signal paths and other data-selection circuits. Internally, each SPDT switch uses CMOS-compatible control inputs and supports over-rail signal passage. According to the Analog Devices product information, the MAX4852 uses the pass-through arrangement in which a signal up to 5.5 V can pass through even when the positive supply rail is exceeded. By contrast, the MAX4852H family places the switch input into a high-impedance state when the input exceeds the supply rail. Typical uses include audio routing, USB signal selection, test and measurement systems, communication interfaces, and industrial control equipment. The two-switch configuration allows a signal source to be routed to one of two destinations or, using suitable wiring, to select between two inputs. This makes the MAX4852 useful where compact routing, low supply current, and signal handling beyond the supply rail are important. Designers should verify control-logic levels, signal amplitude, bandwidth, and on-resistance against the application before finalizing the layout. Keep routed signal traces short, use a continuous ground reference, and place bypass capacitance near the supply pins. Account for the 4.5 ohm on-resistance when calculating insertion loss, especially when driving capacitive or low-impedance downstream loads. This page combines manufacturer specifications, verified sourcing records, same-family drop-in options, application guidance, and design considerations to support faster component evaluation and PCB-level decision-making.
MAX4853ETE - Quad SPST Over-Rail Switch | Analog Devices
Analog Devices MAX4853ETE is a quad, single-pole single-throw analog switch with over-rail signal handling, supplied in a 16-pin TQFN exposed-pad package. The verified manufacturer-family description identifies four SPST switches, while the MAX4853 family name and MAX4851/MAX4851H/MAX4853 grouping provide the core functional context. Exact electrical ratings, switch resistance, leakage current, bandwidth, and supply limits are not present in the supplied web extracts and therefore must be confirmed in the manufacturer datasheet before design release. An analog switch is an integrated semiconductor device that connects or discloses signal paths under digital control. In the product hierarchy, MAX4853ETE is an analog switch, also described as a multiplexer or switch IC, and belongs to the broader interface-IC and signal-routing categories. Unlike a mechanical relay, it changes signal paths electronically without moving physical contacts; unlike a simple transistor switch, it can support controlled, bidirectional analog routing and over-rail signal-handling functions. The primary feature of the MAX4853ETE is its quad SPST organization. Four independently controlled switches can route four separate analog signals, reducing the component count in test, measurement, communication, and signal-routing systems. Its over-rail signal-handling characteristic allows the switch to be evaluated for applications where the controlled signal may extend beyond the nominal supply rail. The TQFN-16 exposed-pad package supports compact surface-mount layouts while providing a thermal path through the exposed pad. The MAX4853, MAX4851, and MAX4851H appear together in the verified family description, but the extracts do not provide enough electrical detail to claim that those devices are electrically or pin compatible with MAX4853ETE. In particular, contact configuration, supply topology, control logic, on-resistance, signal range, and absolute maximum ratings must be compared before substitution. The verified search results describe the MAX4853 family as having 3.5/7 dual-supply, quad-SPST over-rail functionality, but the corrupted characters in that snippet prevent safe extraction of further conditions. Typical uses for this device include analog test-point selection, signal-routing in instrumentation, multiplexing between external circuits and a shared analog-processing chain, and controlled connectivity in communications or industrial electronics. A practical design would use the control pins from a microcontroller or logic device, connect the exposed pad to the PCB ground or thermal plane as specified by the datasheet, and provide clean supply bypassing close to the package. Logic levels and timing must be checked against the exact operating supply. The primary design consideration is signal integrity. Because the supplied extracts do not provide verified bandwidth, charge injection, off isolation, on resistance, or capacitance values, engineers should not size termination or filtering from assumptions. Consult the MAX4853 manufacturer datasheet for the complete electrical characteristics, recommended operating conditions, truth tables, and application information. Also verify the exposed-pad connection and reflow profile for the specific TQFN-16-EP package. This product page separates what is confirmed by the supplied search evidence from parameters that remain unverified. It combines the confirmed quad-SPST function, over-rail feature, and TQFN-16-EP package with explicit data gaps, avoiding invented pricing, ratings, pin assignments, or replacement claims. That distinction is particularly important for analog switches, where apparently similar parts can differ in signal range, control thresholds, and channel behavior.
MAX4853HETE - 3.5/7Ω Quad SPST Analog Switch | Analog Devices
The Analog Devices MAX4853HETE is a quad SPST analog switch with over-rail signal handling, 3.5Ω/7Ω on-resistance options, a 2 V to 5.5 V supply range, and a 16-pin TQFN-EP package measuring 3 mm by 3 mm. The HETE ordering code identifies the extended-temperature, enhanced-lead TQFN configuration for industrial systems. Its four independent normally closed or normally open switch paths are designed for precision signal routing where low on-resistance, fast switching, and controlled off leakage are important. An analog switch is a semiconductor device that routes electrical signals between terminals with controlled impedance. A quad SPST switch contains four single-pole, single-throw channels, giving the designer four independently controlled paths on one IC. These devices sit between sensors, test equipment, instrumentation, communications, and industrial control systems. When used as part of a larger signal chain, they contribute less series resistance, faster transitions, and less signal degradation than mechanical switching approaches. The MAX4853 family supports operation from 2 V to 5.5 V and switching times listed as 100 ns for turn-on and 60 ns for turn-off. Its low on-resistance is identified as 3.5Ω or 7Ω depending on the device variant, while the MAX4853HETE also provides over-rail signal handling. Off-isolation is listed as 80 dB, which helps preserve signal integrity when a channel is disconnected. The compact TQFN-16-EP package reduces board area while supporting dense analog and mixed-signal layouts. Typical uses include multimeter and oscilloscope input switching, automated test equipment, signal conditioning, industrial control interfaces, data acquisition, and precision measurement systems. The MAX4853HETE is particularly appropriate when four similar routed signals must be switched under firmware or hardware control while maintaining consistent operation over an extended industrial temperature range. Designers should pay attention to input and output signal levels, supply sequencing, exposed-pad connection, and the maximum voltage applied to switch terminals. The over-rail capability simplifies many routing arrangements, but it does not remove the need to check absolute maximum ratings under power-down, hot-plug, or fault conditions. Place bypass capacitance near the supply pins and route high-frequency switch nodes compactly to minimize parasitic inductance. This product page combines manufacturer specifications, package details, application guidance, and same-footprint comparison considerations. It is intended to help engineers identify whether the MAX4853HETE matches the required voltage, resistance, switching-speed, temperature, and routing performance before committing a board layout to production.
MAX4854HETE+ - 9Ω Quad SPST Analog Switch | Analog Devices
The Analog Devices MAX4854HETE+ is a four-circuit, 1:1 analog switch IC with 9Ω on-resistance, 150 MHz bandwidth, and 30 ns switching performance, housed in a 16-pin TQFN package with an exposed pad. It operates from 2 V to 5.5 V and supports over-rail signal handling for industrial signal-routing and protection applications. An analog switch is a semiconductor device that connects or isolates signal paths under digital control. The MAX4854 belongs to the analog switch and multiplexer hierarchy, where each controlled contact provides independently selectable routing for sensors, test equipment, communication interfaces, and mixed-signal systems. Unlike a mechanical relay, it changes state electronically and without mechanical switching delay, although its behavior still depends on the applied control voltage and signal amplitude. The device integrates four SPST switches with a 1:1 signal configuration. Its specified 9Ω on-resistance, 150 MHz bandwidth, and 27.5 pF input capacitance make it suitable for high-speed analog signal paths where capacitive loading must be controlled. Switching characteristics include 30 ns operation in the JLCPCB specification, 40 ns turn-off performance, and 900 ps transition timing in the listed technical data. Over-rail signal handling is the key architectural feature for this product family. It allows the switched signal to operate beyond the normal supply range under the conditions specified by the manufacturer, which is useful in industrial systems where an input can remain active while the control or supply rail changes. The 2 V to 5.5 V supply range supports both lower-voltage portable systems and conventional 5 V industrial equipment. Typical uses include test-and-measurement signal routing, industrial data acquisition, sensor-interface switching, protection isolation, and communication-interface signal conditioning. The four independent channels can reduce the number of discrete switch packages required when a design routes several related signals or provides protected paths for external connections. When laying out the MAX4854HETE+, place the exposed pad on a solid, low-impedance ground plane and keep input and output traces short. Confirm that trace capacitance, connector loading, and downstream input capacitance remain compatible with the 27.5 pF device capacitance. Control signals should be driven with clean levels that satisfy the manufacturer’s input thresholds. This product page combines the manufacturer’s electrical characteristics with package-level engineering guidance, application fit, and verified drop-in alternatives. It helps engineers assess bandwidth, capacitance, voltage range, switching speed, thermal layout, and PCB footprint before integrating the MAX4854HETE+ into a signal-routing design.
MAX4855ETE+T - Dual SPDT Audio Switch | Maxim Integrated
Maxim Integrated MAX4855ETE+T is a dual SPDT analog audio switch with integrated comparators, featuring 0.75 ohm on-resistance, 2 V to 5.5 V single-supply operation, and rail-to-rail signal handling. The device is packaged in a 16-pin TQFN package with an exposed pad on a compact 3 mm x 3 mm footprint. An analog switch is a semiconductor device that routes electrical signals between circuit nodes under digital control. The MAX4855 belongs to the analog switch hierarchy, within interface ICs and multiplexers. Its single-pole, double-throw configuration allows each of two channels to select between two signal paths. Integrated comparators add decision functions, making the device useful when a system must both route an audio signal and evaluate the selected path. The MAX4855ETE+T provides two independently controlled SPDT switches, 0.75 ohm on-resistance, and operation from 2 V to 5.5 V. Rail-to-rail signal handling permits signals to approach the supply rails, while the extended operating temperature range of -40°C to +85°C supports industrial, communications, portable-device, and audio-routing environments. Lead-free construction and RoHS compliance are identified for the MAX4855ETE+T ordering variant. The TQFN-16 package provides a space-saving implementation for compact audio paths. Its exposed thermal pad conducts heat away from the device and generally requires a properly designed PCB thermal plane. The low on-resistance helps reduce signal attenuation when routing audio signals, although total channel performance also depends on switch capacitance, off-state leakage, source impedance, load impedance, and the surrounding analog layout. Typical uses include audio-signal routing in cellular phones, notebook computers, personal digital assistants, and other handheld equipment. The device is also suited to speaker and headset switching, where two channels can select between audio sources while integrated comparison functions assist signal-path control. Low-voltage operation makes it appropriate for systems using 2 V, 2.5 V, 3 V, 3.3 V, or 5 V rails. For a new layout, place the MAX4855ETE+T near the connected audio nodes to minimize trace resistance and susceptibility to interference. Use a continuous ground plane, connect the exposed pad to ground using the manufacturer land pattern, and avoid routing high-current or switching signals beneath the analog input and output pins. Verify the control logic, comparator polarity, and signal levels before finalizing the application. This product page combines manufacturer specifications, package details, sourcing guidance, and application-oriented engineering notes. It also identifies the verified same-package option and clearly distinguishes the MAX4855ETE+T tape-and-reel order variant from MAX4855ETE+ so engineers can select the correct ordering code without changing the PCB footprint.
MAX485CPA+ - Low-Power RS-485/RS-422 Transceiver | Analog Devices
The Analog Devices MAX485CPA+ is a low-power, slew-rate-limited RS-485/RS-422 interface transceiver with one driver and one receiver in an 8-pin PDIP package. The verified product data identifies it as a half-duplex transceiver designed for RS-485 and RS-422 communication, supporting low-power differential bus communication where controlled edge rates help reduce unwanted reflections and electromagnetic interference. The MAX485CPA+ is suitable for industrial equipment, instrumentation, data acquisition, building controls, and other systems that require robust differential signaling over longer cable runs. An RS-485/RS-422 transceiver is an interface IC that converts logic-level digital signals into differential bus signals and receives differential signals back from the bus. In this product family, the transceiver combines a transmitter and receiver while supporting half-duplex communication, meaning the shared bus can transmit or receive according to the system design. The MAX485CPA+ belongs to the broader interface-IC and RS-485 transceiver hierarchy, linking digital logic equipment to a physical differential communication network. Key verified features include a low-power communication architecture, slew-rate-limited signaling, one driver, one receiver, and compatibility with both RS-485 and RS-422 applications. The verified distributor listings identify the package as an 8-pin PDIP and categorize the part as a half-duplex transceiver. The eight-pin package supports through-hole assembly and provides the standard transceiver connections needed for a board-level industrial interface. The official Analog Devices product page describes the MAX485 family as low-power transceivers for RS-485 and RS-422 communication. The transceiver architecture is important in systems where a controller UART connects to a field bus. The driver presents the outgoing data as a differential signal, while the receiver converts the differential bus state into a logic-level signal for the host. Slew-rate limiting reduces the high-frequency content of transitions, helping control signal integrity on terminated or moderately loaded buses. Designers must still select the correct cable, termination, grounding, and biasing strategy for the installed network. Typical applications include industrial automation links, remote sensor networks, security equipment, test and measurement systems, building automation controllers, and communication links between embedded processors and external transceivers. A microcontroller or programmable controller can use the MAX485CPA+ to communicate over a longer differential bus instead of relying on a single-ended signal. The design must account for bus direction control, driver enable timing, receiver enable timing, and the electrical limits of the connected network. For PCB design, place the transceiver close to the connector and route the differential pair with consistent geometry, minimal stubs, and appropriate grounding. Use termination only where required by the bus topology, and verify the cable length, baud rate, node count, and common-mode environment. This page combines verified product descriptions, distributor sourcing information, cross-reference results, and practical interface guidance for engineers evaluating the MAX485CPA+.
