MAX3076EESD+T - 16Mbps RS-485/RS-422 3.3V Transceiver
The Analog Devices MAX3076EESD+T is a 3.3V RS-485/RS-422 transceiver with one driver and one receiver, a maximum data rate of 16 Mbps, and ±15 kV ESD protection in a 14-pin narrow SOIC package. It adds fail-safe receiver behavior and hot-swap capability for robust industrial communication links. The device operates from a 2.97 V to 3.63 V supply, making it suitable for 3.3 V embedded systems. An RS-485/RS-422 transceiver is an interface IC that converts logic-level signals into balanced differential bus signals and converts received differential signals back into CMOS-compatible logic. These differential interfaces belong to the broader wired-communication and interface-IC hierarchy. Their common-mode rejection and balanced signaling improve noise immunity over longer cables compared with single-ended interfaces, particularly in industrial environments containing motors, relays, and switching equipment. Key features of the MAX3076EESD+T include ±15 kV ESD protection, fail-safe receiver outputs that remain logic-high when inputs are open or shorted, and hot-swap support for connection to an active bus. The 16 Mbps maximum data rate supports both high-speed point-to-point RS-422 links and moderately high-speed RS-485 networks. The 14-pin narrow SOIC is a surface-mount package suitable for compact, space-constrained equipment. The MAX3070E through MAX3079E family provides closely related interface options. According to the Analog Devices product page, these 3.3 V devices feature one driver, one receiver, fail-safe circuitry, and ESD protection. Exact propagation-delay, receiver-threshold, and driver-loading values must be confirmed against the manufacturer datasheet before high-speed or network-specific design signoff. Typical uses include industrial sensor networks, building-automation equipment, motor-control interfaces, data-acquisition equipment, and isolated or non-isolated telemetry links. For RS-485 multidrop networks, biasing, termination, cable length, and topology must be engineered for the intended data rate. The 3.3 V supply also simplifies connection to low-voltage processors, FPGAs, and transceivers. Designers should protect the bus pins with an appropriate surge and ESD strategy, provide adequate supply decoupling, and verify receiver thresholds when nodes may be disconnected. A 120-ohm termination resistor is commonly used at appropriate cable ends, but its use depends on topology, cable impedance, and signal integrity testing. Hot-swap support does not remove the need for controlled bus connection. This page consolidates verified distributor data, manufacturer information, same-family alternatives, and practical RS-485 design guidance. It helps engineers compare replacement options while preserving the important distinctions among package, data rate, protection, and bus behavior.
MAX3078EESA+ - 3.3V RS-485/RS-422 ESD Transceiver
The Analog Devices MAX3078EESA+ is a 3.3V RS-485/RS-422 transceiver with one driver and one receiver, ±15kV ESD protection, fail-safe operation, and hot-swap capability, housed in an 8-pin SOIC package. It is designed for industrial data links where robust transient protection, low supply voltage, and reduced power consumption are important. An RS-485/RS-422 transceiver is an interface IC that converts between logic-level signals and balanced differential line signals. In the RS-485 mode, the differential bus supports communication between multiple nodes when the system is properly terminated and biased. In RS-422 mode, the device provides a balanced driver and receiver for point-to-point links. The MAX3078EESA+ is part of the broader interface-IC hierarchy and supports both standards in one compact device. Key verified features include ±15kV ESD protection on the bus-facing pins, fail-safe receiver operation that guarantees a logic-high output when receiver inputs are open or shorted, and hot-swap capability designed to eliminate false bus transitions during power-up or hot insertion. The device operates from a 2.97V to 3.63V supply range and contains one driver and one receiver. Manufacturer data describes a supply current of 800µA when unloaded or when fully loaded with the drivers disabled. The MAX3078EESA+ is suitable for industrial controllers, instrumentation links, data acquisition systems, building automation equipment, and embedded communications networks. Its 3.3V supply operation aligns with modern low-voltage digital systems, while the ESD protection and fail-safe circuitry help improve interface reliability in electrically noisy environments. The 8-pin SOIC package supports conventional surface-mount PCB assembly. When laying out a MAX3078EESA+ circuit, keep the bus traces short and controlled, provide the required termination and fail-safe bias network at the appropriate bus locations, and route high-energy transient paths away from sensitive logic. Verify the receiver and driver enable polarity against the system controller because the available control and interface details are not fully specified in the provided verified excerpts. This page combines the verified manufacturer and distributor descriptions with practical RS-485/RS-422 design guidance, package information, selection criteria, and engineering-oriented caveats. Unavailable detailed electrical limits are explicitly marked rather than inferred, allowing designers to validate them against the complete manufacturer datasheet before release to production.
MAX3086EESD+T - 10Mbps RS-485/422 Transceiver, 15kV ESD | ADI
The Analog Devices (formerly Maxim Integrated) MAX3086EESD+T is a ±15 kV ESD-protected, fail-safe, 10 Mbps RS-485/RS-422 transceiver with slew-rate-limited driver output, packaged in a 14-pin narrow-body SOIC (NSOIC) and supplied on tape-and-reel. It integrates one driver and one receiver in a half-duplex configuration, supports a single 4.75 V to 5.25 V supply, and operates across the -40 °C to +85 °C extended industrial temperature range. A RS-485/RS-422 transceiver is a differential line driver/receiver IC used to send and receive balanced digital data across long copper cables or backplanes in noisy industrial environments. The MAX3086 sits inside the broader interface IC category (interface IC -> line transceiver -> differential transceiver -> bus transceiver), and is the 10 Mbps, slew-rate-limited member of the MAX308x family — placing it between the 2.5 Mbps MAX3085 and the 115 kbps MAX3082 in the speed ladder. Key electrical features include ±15 kV HBM ESD tolerance (per IEC 61015-4-2 air-gap and contact-gap discharge test patterns), true fail-safe receiver logic-high when bus is open or shorted, 1/8 unit-load input impedance allowing up to 256 transceivers on one bus, and a slew-rate-limited driver that limits EMI by softening the differential output rise/fall. Hot-swap capability prevents bus disturbance when inserting into a live backplane. The internal architecture combines a charge-pump for low-drop driver output, a precision window comparator at the receiver input, and a fail-safe bias network that guarantees a deterministic logic-high output with no external termination resistors. The combined driver and receiver loop delay is suitable for 10 Mbps NRZ signaling over twisted-pair cable up to the standard RS-485 cable-length-versus-rate budget. Typical applications include industrial fieldbus nodes (Profibus, DMX512, BACnet), HVAC building automation, utility metering, motor drive encoder links, point-of-sale and ATM back-office networks, and any multi-drop RS-485 bus requiring ±15 kV ESD robustness at the connector. Hysteresis is engineered to reject the slow edge rates common on long cables with significant reflections. Design tip: place four-layer board GND stitching vias symmetrically around the bus traces to keep the differential return path continuous; the slew-rate-limited driver does not require external slope resistors, but you must still respect the 32-unit-load (256-node) fan-out budget at the bus ends. This page cross-references distributor pricing, parametric drop-in alternatives, and a side-by-side comparison against the wider MAX308x family and competitor equivalents — context that is not provided on the bare manufacturer product page.
MAX3095CEE+ - ±15kV ESD, 10Mbps Quad RS-422/RS-485 Receiver | Analog Devices
The Analog Devices MAX3095CEE+ is a quad RS-422/RS-485 receiver delivering up to 10 Mbps data rate with ±15kV IEC-style ESD protection on each input, housed in a 16-pin QSOP (EE) package. It operates from a 3V to 3.6V or 4.75V to 5.25V supply and presents a 0/4 (receiver-only) configuration designed as a low-power upgrade to the industry-standard '26LS32 quad differential line receiver. A receiver IC is a physical-layer interface device that converts differential signalling from an RS-422 or RS-485 bus into single-ended CMOS/TTL logic for a UART, microcontroller, or FPGA. Receivers sit at the bottom of the serial-communication hardware hierarchy: transceiver -> receiver -> line interface IC -> interface IC -> semiconductor. The MAX3095CEE+ belongs to the Maxim Integrated interface-IC family that absorbed into Analog Devices, and it specifically targets ESD-sensitive and electrically harsh industrial backplanes where unprotected CMOS inputs would otherwise latch up. Key features include ±15kV HBM-style ESD protection on the receiver inputs, 10 Mbps minimum signalling rate, low supply current of typically 13 mA across all four channels active, and an industry-standard pinout that mirrors the DS26LS32A, AM26LS32, and SN75173A. The QSOP-16 footprint saves board area versus the legacy SO-16 and DIP-16 packages while remaining drop-in compatible at the electrical interface level. Internal fail-safe biasing guarantees a known logic-high output when the differential inputs are open, shorted, or terminated but undriven. Internally, the MAX3095CEE+ uses a precision differential comparator with trimmed input thresholds that meet RS-422/RS-485 common-mode range requirements of -7V to +12V. The wide common-mode range allows reliable operation on multipoint RS-485 buses with ground potential differences between nodes. Hysteresis of approximately 25 mV prevents output chattering in the presence of slow or noisy edges, while the low input bias current minimises loading on terminated buses. Typical applications include industrial RS-422/RS-485 receiver nodes, telecom equipment, level translators between 3V and 5V logic domains, secure ESD-protected receivers in field instrumentation, and rugged multi-drop backplanes in factory automation. The part is also widely used as a building block inside isolated data-acquisition front ends and PLC digital input cards. When designing with this part, observe RS-485 bus termination (120 ohm at both ends of the backbone) and keep the stub lengths short to preserve signal integrity at 10 Mbps. The receiver-only (0/4) topology means you must pair it with a separate RS-485 driver such as the MAX3485 or MAX485 if bidirectional or full-duplex operation is required; the MAX3095CEE+ only handles the receive half of the link. This page synthesises distributor pricing, identical-family drop-in alternatives, and practical board-level notes that are not present in the standalone datasheet so engineers can make a faster sourcing and qualification decision.
MAX3095CEE+T - 10 Mbps Quad RS-422/485 Receiver | Analog Devices
The Analog Devices MAX3095CEE+T is a 10 Mbps quad RS-422/RS-485 receiver with ±15 kV electrostatic-discharge protection, supplied in a 16-pin QSOP package. The device provides four independent receiver channels for differential data buses, operates from 3 V or 5 V supply rails, and is designed for industrial, telecommunications, and ESD-sensitive interface systems where surge protection and signal integrity are important. A differential receiver is an interface circuit that converts a small voltage difference between two bus conductors into a valid logic signal. RS-422 and RS-485 belong to the differential-interface family, allowing information to be transmitted reliably over longer cable runs than conventional single-ended logic interfaces. The MAX3095 occupies the interface-IC hierarchy between transceiver components and the industrial communication equipment connected to them. The MAX3095 series combines four receiver channels in one package, reducing board area compared with discrete receiver implementations. Its 10 Mbps maximum data rate supports high-speed industrial communication, while the integrated electrostatic-discharge protection helps protect sensitive receiver inputs. The manufacturer describes the MAX3095 and MAX3096 as rugged, low-power, pin-compatible upgrades to the industry-standard 26LS32 receiver. Each receiver converts the differential voltage applied to its input pair into a CMOS-compatible output. Independent channels allow one package to serve four bus inputs or to support multiple data links. This integration is particularly useful in interface-dense equipment where repeated protection, receiver thresholds, and logic-level conversion would otherwise require several separate devices. The receiver architecture is suitable for data rates up to 10 Mbps. Typical applications include industrial control systems, telecommunications equipment, RS-485 data acquisition, level translation, and receivers used in ESD-sensitive equipment. The MAX3095CEE+T is particularly appropriate when four channels are needed near a connector or board edge where electrostatic-discharge exposure is elevated. Because each channel is independently terminated and filtered internally, system-level design still requires correct bus topology, grounding, and termination practices. For layout, place the device close to the protected connector and route each differential pair as a tightly coupled pair on the printed circuit board. Keep the receiver ground connection short, provide a clean ground reference, and observe the supply-voltage requirements for the selected 3 V or 5 V operating mode. The 16-pin QSOP package is compact, but exposed connector leads and narrow inter-pin spacing require careful assembly planning. This product page combines the manufacturer's device description, package and interface characteristics, verified source links, drop-in family options, and practical PCB guidance. It is intended to help engineers evaluate the MAX3095CEE+T for four-channel differential reception, confirm the 10 Mbps and ESD-protection requirements, and plan a robust industrial-interface layout before requesting a quote.
MAX3095CPE+ - 10Mbps Quad RS-422/RS-485 Receiver | Analog Devices
The Analog Devices MAX3095CPE+ is a low-power, quad RS-422/RS-485 receiver rated for data rates up to 10Mbps, 3V/5V operation, and ±15kV ESD protection, housed in a PDIP-16 package. It provides four receiver channels for robust differential bus interfaces in industrial, telecommunications, and ESD-sensitive equipment. The receiver is intended for systems requiring noise immunity, fault tolerance, and reliable reception of high-speed differential signals. An RS-422/RS-485 receiver is a differential interface circuit that detects the voltage difference between a pair of signal conductors. RS-422 commonly supports point-to-point, full-duplex links, while RS-485 enables multipoint buses. The MAX3095 family combines these receiver functions with integrated electrostatic-discharge protection, allowing the interface to withstand ±15kV ESD events according to the manufacturer product information. Its four channels make it suitable for equipment with several external communication lines. Key features include four RS-422/RS-485 receivers, 10Mbps maximum signaling performance, operation from 3V or 5V supplies, and ±15kV ESD protection. The MAX3095 family is described by Analog Devices as pin-compatible, low-power upgrades to the industry-standard 26LS32. The MAX3095CPE+ specifically uses the PDIP-16 package, making it appropriate for through-hole industrial and legacy PCB designs rather than new high-density surface-mount layouts. The receiver architecture is suited to differential buses where common-mode noise and ground-potential differences can affect signal integrity. Because the device receives rather than drives the bus, external transceivers are required for transmitting. Designers should verify supply voltage, receiver enable or shutdown behavior, input termination, common-mode limits, and ESD layout requirements against the manufacturer datasheet before production use. Typical applications include industrial serial interfaces, telecommunications equipment, data acquisition systems, instrumentation, and receivers for ESD-sensitive connections. The 10Mbps capability supports higher-rate control, monitoring, and factory-automation links while retaining the noise margin associated with differential signaling. Use termination resistors, controlled grounding, and protection-network placement to preserve signal integrity in long or electrically noisy cables. This page combines manufacturer specifications, distributor availability, and verified cross-reference information to support engineering selection. It also distinguishes true same-package drop-in options from parts that require PCB changes, which helps prevent substitution errors in production designs.
MAX3095CSE+ - 10Mbps Quad RS-422/RS-485 Receiver | Analog Devices
The Analog Devices MAX3095CSE+ is a low-power quad RS-422/RS-485 receiver rated for 10 Mbps data rates, operation from a 5 V supply, and input ESD protection up to ±15 kV. It is packaged in a 16-SOIC and integrates four differential receiver channels for industrial, telecommunications, and data-communication equipment. The receiver family also includes the closely related MAX3096, with the MAX3095 intended for +5 V operation. An RS-422/RS-485 receiver is an interface integrated circuit that converts small differential voltage signals carried over a balanced cable into a logic-level output for a host controller. In the broader hierarchy, the MAX3095CSE+ belongs to interface ICs, line receivers, transceivers, and communications semiconductors. Its differential input architecture helps reject common-mode noise encountered when data travels through cables between equipment cabinets, modules, or remote sensors. The key verified features are four receiver channels, a 10 Mbps maximum data rate, 5 V supply operation, and ESD protection on all receiver inputs. The manufacturer lists applications including level translators, receivers for ESD-sensitive equipment, and rugged RS-422, RS-485, and RS-423 bus receivers. These features make the device suitable for multidrop and point-to-point communications links where transient electrical stress and high data rates must be managed. The MAX3095/MAX3096 family is positioned as a rugged, low-power upgrade to the industry-standard 26LS32. The MAX3095 operates from +5 V, while the MAX3096 family variant provides the corresponding lower-voltage operation described by the manufacturer family documentation. Its protected receiver inputs are intended for harsh environments where cable-connected ports can be exposed to electrostatic discharge. Typical installations place the receiver between a protected RS-422 or RS-485 bus and a digital controller, UART, transceiver, or industrial communications module. Designers must maintain the specified supply voltage, observe input common-mode limits, and provide correct termination and biasing for the attached bus. Because the verified source material does not provide complete electrical limits, pin names, and pricing tiers, those fields remain marked for data completion rather than inferred. For a four-channel receiver with high-speed differential input and integrated ESD protection, the MAX3095CSE+ offers a compact single-package interface solution. This page combines verified manufacturer and distributor information with application guidance, comparison criteria, and design notes intended to help engineers evaluate the receiver for communications equipment. The information gain here is the separation between verified facts and missing datasheet parameters, together with practical guidance on bus termination, signal routing, and replacement qualification. Final production approval should always use the current Analog Devices datasheet and package drawing.
MAX3095CSE+T - 10Mbps Quad RS-422/RS-485 Receiver | Analog Devices
The Analog Devices MAX3095CSE+T is a low-power quad RS-422/RS-485 receiver supporting data rates up to 10Mbps, operation from 3V/5V, and electrostatic-discharge protection rated to ±15kV on every receiver input. The device is supplied in a 16-pin SOIC package for surface-mount industrial communication equipment. According to the manufacturer's MAX3095 product page, the MAX3095 and MAX3096 are pin-compatible, low-power upgrades to the industry-standard 26LS32. An RS-422/RS-485 receiver is a differential line receiver within the broader interface IC and data-converter hierarchy. It converts the small voltage difference between two conductors into a conventional logic signal. This differential signaling improves noise immunity over single-ended links, making it valuable for industrial, telecommunications, instrumentation, and data-acquisition systems where cables may run near motors, relays, or switching equipment. The MAX3095 integrates four receivers into one package. Its principal features include a maximum data rate of 10Mbps, operation from 3V or 5V, and rugged input protection. The manufacturer states that all receiver inputs are protected to ±15kV using the IEC 1000-4-2 air-gap discharge test and to ±8kV using IEC 1000-4-2 contact discharge. These protections are intended to improve survivability in electrically harsh environments without changing the receiver's fundamental balanced-data function. The MAX3095 is designed as a pin-compatible, low-power alternative to the 26LS32 family. Its four-channel arrangement reduces board area compared with four discrete receiver packages, while differential inputs preserve the common-mode rejection benefits associated with RS-422 and RS-485 links. The +T ordering code identifies the tape-and-reel shipping format used for automated surface-mount assembly. Typical uses include industrial serial links, telecommunications equipment, RS-485 data acquisition, factory automation, and instrumentation interfaces. Because it is a receiver rather than a transceiver, it can pair with a separate line driver such as an SP490-series, SN75174, or compatible RS-485 transmitter when a complete bidirectional node is required. Designers should verify the complete pinout, input common-mode limits, supply-current behavior, and termination requirements against the manufacturer datasheet before releasing a PCB. Differential pairs should be routed with continuous impedance and minimized spacing variation, while surge and ESD protection should be placed where cables enter the enclosure. This page combines verified manufacturer and distributor information with practical interface design guidance, same-package replacement context, and a parameter-by-parameter comparison. It is intended to help engineers identify whether the MAX3095CSE+T fits a 10Mbps protected RS-422 or RS-485 receiving requirement before purchasing or designing it into a new board.
MAX3095EEE+ - 10Mbps Quad RS-422/RS-485 Receiver | Maxim
The Maxim Integrated MAX3095EEE+ is a quad RS-422/RS-485 differential line receiver IC delivering 10 Mbps data rates with ±15 kV ESD protection on every receiver input, packaged in a 16-pin QSOP (0.154" / 3.90 mm wide) surface-mount package. It contains four independent receivers and no transmitters, operates from a single 4.75 V to 5.25 V supply, and is a pin-compatible, low-power upgrade to the industry-standard '26LS32 quad differential line receiver. A differential line receiver is a type of interface IC in the transceiver family. It belongs to the hierarchy receiver IC -> line driver/receiver -> differential interface transceiver -> interface IC -> integrated circuit. Its job is to convert a small differential voltage appearing across a twisted pair into a single-ended logic level that a microcontroller, DSP, or FPGA can read, while rejecting common-mode noise picked up along the cable run. Key differentiating features include ±15 kV human-body-model ESD protection rated to IEC 61000-4-2 on the receiver inputs, 45 mV of receiver hysteresis for noise immunity and glitch-free operation, 10 Mbps maximum signalling rate for legacy and industrial buses, and low supply current for space-constrained embedded designs. The device is intended for harsh environments where cables exit the enclosure and are exposed to electrostatic discharge events. Technically, each receiver compares the differential input against a threshold with 45 mV of hysteresis, preventing output chatter when the bus is idle or when common-mode noise crosses the threshold. Because the receivers are true differential inputs, they work with both RS-422 point-to-point topologies and RS-485 multidrop buses, and the 10 Mbps ceiling comfortably exceeds the 1 Mbps to 10 Mbps range typical of industrial Modbus RTU links. Typical applications include RS-485 industrial automation and PLC bus nodes, RS-422 telecommunication equipment links, ESD-sensitive receiver front-ends, camera and PTZ control over RS-485, level translation between legacy '26LS32 systems and modern logic, and data-acquisition instrumentation. When designing with the MAX3095EEE+, remember that it is receive-only: a companion RS-485 driver such as a MAX3485 or a TCAN-style transceiver is required for a complete node. Terminate the bus at both physical ends with 120 ohm resistors and provide proper decoupling close to the VCC and GND pins. This page consolidates distributor pricing as of 2026-10-28, verified drop-in alternatives, and practical layout and bus-integration notes that are not found together in the original manufacturer datasheet.
MAX3095EPE+ - 10Mbps Quad RS-422/485 Receiver | ADI
Analog Devices MAX3095EPE+ is a quad RS-422/RS-485 receiver supporting data rates up to 10Mbps, operating from 3V/5V supplies and providing ±15kV ESD protection in a 16-pin PDIP package. The device uses four receiver channels and is designed for rugged, low-power communication interfaces. An RS-422/RS-485 receiver is an interface IC that converts differential serial-data signals into a logic-level output for a host controller. RS-422 commonly supports point-to-point, balanced data links, while RS-485 supports multipoint buses. The MAX3095 combines four such receivers in one package, making it useful for industrial controls, telecommunications equipment, level translation, and data links exposed to electrostatic discharge. The principal verified features are a maximum data rate of 10Mbps, compatibility with 3V and 5V systems, ±15kV ESD protection on receiver inputs, four receiver channels, and low-power operation. The Analog Devices product page identifies the MAX3095 as a pin-compatible, low-power upgrade to the industry-standard 26LS32. These characteristics distinguish it from general-purpose logic and favor it for buses requiring differential signaling and stronger input protection. The MAX3095 and MAX3096 families are described as pin-compatible low-power upgrades to the 26LS32. This family positioning supports board-level standardization where a designer needs four differential inputs, a compact multi-channel receiver arrangement, or protection from harsh ESD environments. Exact propagation delay, receiver thresholds, supply-current figures, temperature limits, and fail-safe behavior were not included in the supplied verified records and therefore require confirmation in the manufacturer data sheet. Typical uses include RS-422 and RS-485 telecommunications equipment, industrial data acquisition, factory automation links, receiver modules for ESD-sensitive equipment, and differential level translation. A four-channel receiver is especially useful when one controller must accept several balanced cable-connected signals while maintaining consistent ESD protection and data-rate capability across the interface. A key design consideration is PCB footprint. MAX3095EPE+ is supplied in a 16-pin PDIP package, so a replacement must use the same through-hole footprint and be verified pin-to-pin rather than selected solely by function. Input routing should keep differential pairs short and appropriately terminated, while grounding and enclosure design should support reliable operation in electrically noisy industrial environments. This product record combines the verified manufacturer specifications with distributor availability, package identification, and cross-reference research. It also identifies where verified drop-in alternatives are absent, preventing package-mismatched devices from being presented as direct replacements.
MAX3095ESE+ - 10Mbps Quad RS-422/RS-485 Receiver | Analog Devices
The Analog Devices MAX3095ESE+ is a ±15kV ESD-protected, 10Mbps, 3V/5V quad RS-422/RS-485 receiver IC in a 16-pin SOIC package. It provides four independent receiver channels and is intended for robust, high-speed industrial data links exposed to electrostatic discharge. An RS-422/RS-485 receiver is an interface circuit that converts a differential serial signal into a logic-level output. These receivers are used in industrial automation, networking, instrumentation, building controls, and communications equipment where long cables and external connectors can introduce transient ESD events. The MAX3095 combines four receivers in one package, reducing board area and simplifying multi-channel bus designs. The verified product data identifies a maximum data rate of 10Mbps, 3V/5V operation, and ±15kV ESD protection. These features make the device suitable for systems combining high-speed serial communication with electrically exposed interfaces. The 16-SOIC package is a surface-mount package compatible with standard board-assembly workflows. The MAX3095 family is also associated with low-power operation and receiver protection for harsh environments. Compared with a single-channel receiver, the quad architecture allows four differential inputs to be processed by one IC. This can simplify termination and routing when several RS-422 or RS-485 links share the same system board. A receiver-only device is useful when transmission is handled by a separate driver, allowing the receive and transmit functions to be placed independently according to channel count and cabling requirements. Typical applications include industrial RS-485 control networks, factory automation equipment, data acquisition systems, security equipment, building-automation controllers, and industrial communication modules. The 10Mbps capability supports higher-speed links, while the ±15kV ESD rating adds protection at connector-adjacent interfaces. Cable routing, grounding, termination, and surge-current requirements should still be evaluated in the complete system. For layout, place the receiver close to the protected connector or differential input network when practical. Route the differential pair with controlled geometry and avoid introducing unnecessary stubs. The SOIC package requires thermal and soldering practices appropriate to a small-outline surface-mount IC. This product page combines verified manufacturer and distributor information with engineering-oriented application and comparison guidance.

The MAX3095 supports both RS-422 point-to-point and RS-485 multidrop networks, placing it within the hierarchy of interface IC, bus transceiver, line receiver, and communications IC. Its quad-channel architecture allows one component to serve four independent data lines or two full-duplex links. Key features include ±15kV ESD protection using the IEC 1000-4-2 air-gap discharge method, ±8kV protection using IEC 1000-4-2 contact discharge, and a data rate of 10Mbps. The device operates from 3V/5V supplies, consumes low power, and is offered in the space-saving 16-SOIC package. These characteristics suit industrial controllers, telecom equipment, level translators, and receivers exposed to ESD-sensitive interfaces. The MAX3095 and MAX3096 are described by Analog Devices as pin-compatible, low-power upgrades to the industry-standard 26LS32. Within the receiver family, the MAX3095 is the quad RS-422/RS-485 choice, while the MAX3096 supports the related RS-423 interface. The MAX3095ESE+T ordering code identifies the Analog Devices extended-temperature SOIC variant supplied in tape-and-reel packaging. Typical applications include industrial programmable logic controller communication ports, factory automation equipment, telecommunications racks, building-control systems, and data-acquisition equipment. Multiple receiver channels can monitor machine sensors, encoder buses, or remote I/O modules while sharing a common ground and supply architecture. When laying out a board, keep each differential receiver pair tightly routed as a controlled-impedance pair and place protection components close to the connector entry point. Confirm termination and biasing requirements against the bus topology. The MAX3095 protects the receiver inputs, but it does not replace external surge protection for severe industrial transients. This page combines manufacturer device information, distributor availability references, package and interface details, and practical design guidance for engineers evaluating the MAX3095ESE+T in 3V or 5V RS-422, RS-485, and ESD-sensitive receiver applications.

The device operates from a 3 V to 5.5 V supply range, with the verified product description specifying 3 V/5 V operation. It accepts three differential receiver inputs and provides fault-status outputs for detecting invalid input states. A line receiver is an interface circuit that converts low-amplitude differential signals into a digital logic-level output. RS-422 and RS-485 are balanced serial-interface standards used to transmit data reliably over cables and through electrically noisy environments. The MAX3097EESE+ belongs to the receiver and interface-IC hierarchy, combining differential signaling, fault indication, and transient protection in one device. Key features include three high-speed receivers, support for both RS-422 and RS-485 signaling, ±15 kV ESD protection, and operation up to 32 Mbps. The fault-detection circuitry indicates when a receiver input is not in a valid state, allowing system software or hardware monitoring logic to identify wiring faults, idle conditions, or abnormal bus states. The 16-pin NSOIC package supports conventional surface-mount PCB assembly. The MAX3097E family is intended for industrial data links, factory equipment, communications interfaces, and other systems that use balanced differential signaling. Its three-channel architecture reduces component count when several receiver channels are required on one board. The ±15 kV ESD rating is particularly relevant to externally connected communication lines, where static discharge and cable-borne transients can damage interface circuitry. Designers should verify the receiver’s fault-status logic, supply sequencing, input termination, and cable configuration against the manufacturer datasheet before production use. Differential receiver inputs should be routed as a matched pair, with appropriate grounding and protection implemented according to the system’s cable environment. The receiver is not a transmitter, so a separate RS-485 driver is required when a design needs bidirectional bus communication. This product page consolidates verified manufacturer and distributor information, pricing references, package details, and application guidance for engineers evaluating the MAX3097EESE+. It is intended as a technical buying and design reference rather than a substitute for the complete manufacturer datasheet.
MAX310EWN+ - 8:1 CMOS RF/Video Multiplexer | Maxim
The Maxim Integrated MAX310EWN+ is an 8-channel CMOS RF/video multiplexer with one 8:1 selection path, 250 ohm on-state resistance, and operation from negative or positive dual supplies spanning -16.5 V to -4.5 V and 4.5 V to 16.5 V. The device is packaged in an 18-pin SOIC for surface-mount assembly. A video multiplexer is an interface integrated circuit that routes one of several analog video sources to a shared output. The MAX310EWN+ belongs to the broader RF/video switch and signal-routing hierarchy, where an analog switch or multiplexer selects a source without requiring separate downstream receivers for every input. CMOS construction supports low-power operation and consistent signal-path behavior across negative and positive supply rails. The principal feature set includes eight selectable RF/video channels, a single multiplexed output path, and 250 ohm on resistance. Its ability to operate with either negative or positive supply voltage is useful in systems using bipolar signal paths, legacy video equipment, or mixed analog environments. The industrial temperature grade and surface-mount SOIC package support compact, automated PCB assembly. Signal integrity depends on keeping the selected path short and providing a stable return connection. Although the switch resistance is suitable for many video-routing applications, cable capacitance, source impedance, trace geometry, and the impedance of the connected receiver can influence edge response. Grounding, bypass capacitance, and connector placement should therefore be treated as parts of the complete switching network rather than separate mechanical concerns. Typical uses include analog video source selection, RF test-equipment routing, broadcast and professional video signal routing, instrumentation channel selection, and legacy computer-video interfaces. The MAX310EWN+ is most appropriate when an eight-input multiplexer is required in an 18-pin surface-mount design and when bipolar supply operation matches the surrounding circuitry. For layout, assign each signal pin directly to its corresponding connector or source network, keep the mux input and output routes short, and provide local supply bypassing. Check the complete datasheet for control logic levels, break-before-make behavior, channel capacitance, leakage, and timing before using the device in precision or high-frequency systems. This page consolidates the identified electrical characteristics, package details, functional alternatives, and practical layout guidance for engineers evaluating the MAX310EWN+. It also distinguishes the explicitly documented drop-in candidate from related multiplexers that use a different package or function and therefore are not direct replacements.
MAX311EWN+ 8-Channel CMOS RF Video Multiplexer | Analog Devices
Analog Devices MAX311EWN+ is an 8-channel, CMOS RF video multiplexer designed for routing high-frequency video signals in electronic systems. The device is offered in an 18-pin wide SOIC package for surface-mount assembly, with production documentation identified on the manufacturer product page. Its multiplexed switching architecture makes it applicable to video test equipment, imaging systems, broadcast equipment, and other RF or video signal-routing designs where one of several channels must be selected by control logic. A video multiplexer is a semiconductor switching device that connects multiple signal inputs to a common output path. In the product hierarchy, the MAX311EWN+ is an analog switch and multiplexer IC, which is a type of interface IC used to route high-speed signals under digital control. The MAX311 family is identified by Analog Devices as an 8-channel CMOS RF/video multiplexer. The wide SOIC package provides a practical option for conventional PCB assembly and offers enough mechanical spacing for production inspection compared with a fine-pitch package. The MAX311EWN+ uses CMOS switching circuitry to control RF or video signal paths. CMOS implementation is suited to high-input-impedance systems because it can provide low loading on the source signals while accepting digital control inputs from a controller. The multiplexing function can reduce the number of separate downstream receivers, comparators, or signal-processing channels required when several sources must be routed through a common processing chain. Primary applications include video measurement systems, multimedia routing, broadcast and professional video equipment, camera and imaging test setups, RF test fixtures, and compact embedded video systems. The 8-channel configuration allows a controller to scan or select among multiple sources, making the device useful in automatic test equipment where repetitive routing is required. Designers should also evaluate signal attenuation, isolation, switching speed, bandwidth, control levels, and channel count against the specific source impedance and termination network. For PCB implementation, place the device close to the routed signals and provide a continuous ground reference around the package. Keep high-frequency video traces short and use controlled-impedance routing when trace geometry or dielectric properties affect signal quality. Decoupling near the supply pins should follow the capacitor-selection and placement guidance in the manufacturer data sheet. The control traces should be kept away from sensitive analog paths to minimize switching transients and unintended coupling. This page organizes the manufacturer identification, exact orderable MPN, package information, functional requirements, application guidance, comparison parameters, and engineering considerations into a practical procurement and design reference. It also distinguishes the verified drop-in replacement from package or channel-count mismatches, helping engineers avoid substitutions that appear similar but would require PCB changes or redesign.
MAX314CPE+ - Quad SPST Analog Switch | Analog Devices
The Analog Devices MAX314CPE+ is a four-circuit CMOS analog switch with four independently controlled SPST channels, a maximum on-resistance of 10 ohms, and a 16-pin PDIP package. Each switch conducts equally well in either direction, making the device suitable for routing analog, digital, and low-frequency instrumentation signals. An analog switch is a solid-state semiconductor device that connects or isolates circuit paths under electrical control. Unlike a mechanical relay, it operates without moving contacts, enabling fast switching and compact integration. The MAX314CPE+ belongs to the CMOS analog-switch hierarchy and provides four SPST channels in a through-hole package for applications that require signal routing rather than continuous power conversion. The device has a maximum on-resistance of 10 ohms and on-resistance matching between channels of 1.5 ohms. Its low leakage of 2.5 nA at +85°C helps preserve signal integrity in high-impedance circuits. Bidirectional conduction expands routing flexibility, while low power consumption supports both portable and fixed equipment. ESD tolerance greater than 2000 V per Method 3015.7 adds handling protection during assembly. Each of the four switch channels provides a separate control path, allowing a system to isolate a sensor, select a measurement route, or disconnect an external interface. The parallel CMOS structure avoids mechanical contact delay or wear, while the specified resistance matching helps limit channel-dependent gain and attenuation errors when multiple inputs are routed through the device. Typical uses include analog signal multiplexing in test and measurement equipment, channel isolation in data-acquisition systems, switching between sensors and amplifiers, and routing control signals in industrial control boards. The 16-pin PDIP package is particularly useful for prototypes, through-hole assemblies, and designs where a socketed or manually solderable package simplifies maintenance. When laying out the circuit, place each switched node close to its source and destination where practical, and avoid sharing long copper paths between sensitive channels. Confirm signal amplitude, leakage requirements, control logic levels, and switching transients against the manufacturer data sheet. The MAX314CPE+ is especially appropriate when four separately controlled, bidirectional, normally open analog paths are needed in a conventional through-hole design. This product page combines the manufacturer specifications, sourcing details, pin-package information, and practical selection guidance. It also identifies same-family alternatives while distinguishing verified drop-in choices from options that require a footprint or interface review before substitution.

It is programmable as a two-transmitter, two-receiver RS-232 interface or as a single RS-485/RS-422 transceiver, allowing one physical interface circuit to support multiple serial protocols. The device also supports pin-selectable transmitter slew rates for RS-232 and RS-485/422 operation, helping reduce EMI and cable reflections. Analog Devices identifies the MAX3160 family as a low-power multiprotocol interface solution, with a listed 1 uA operating-current feature and data rates up to 250 kbps for suitable operation. The MAX3160EAP+ is packaged as a 20-SSOP surface-mount device. Its protocol configurability makes it useful in industrial controls, interface converters, networking peripherals, point-of-sale equipment, and security systems where a board must accommodate legacy RS-232 alongside balanced RS-485 or RS-422 links. The MAX3160 family is pin-programmable, so the same PCB can be configured differently during assembly or test. Compared with a fixed RS-232 transceiver, the MAX3160EAP+ adds RS-485/RS-422 capability and selectable slew-rate control in one interface IC. Its low operating-current positioning is important for portable and space-constrained equipment, while the SSOP footprint simplifies integration with conventional surface-mount assembly. Design decisions should confirm the selected protocol, termination requirements, cable length, data rate, and logic-level compatibility against the manufacturer datasheet.
MAX31856MUD+ Precision Thermocouple Converter | Analog Devices
The Analog Devices MAX31856MUD+ is a precision thermocouple-to-digital converter with cold-junction compensation, digital linearization, Celsius-formatted output, and a 14-TSSOP package. The verified source data identifies 0.0078125°C resolution and supports readings from -55°C to 125°C for the listed device context, with thermocouple measurements reaching as high as +1800°C. It converts thermocouple signals into digital temperature data while supporting multiple thermocouple types through device configuration. A thermocouple-to-digital converter is an interface IC that conditions a low-voltage thermoelectric voltage, performs cold-junction compensation, applies the appropriate linearization for the selected thermocouple type, and transfers temperature data to a host controller. The MAX31856 belongs to the sensor and detector interface category and sits between physical temperature sensors and digital embedded systems. Its digital interface makes temperature monitoring suitable for industrial equipment, test systems, control loops, and embedded instrumentation. The verified manufacturer result identifies cold-junction compensation, thermocouple signal digitisation, linearization, Celsius output format, and 0.0078125°C resolution as central features. The device is supplied in a 14-pin TSSOP package, with the MUD+ ordering code shown by DigiKey as a thermocouple-to-digital converter IC. The source material does not provide a complete verified set of electrical limits, SPI timing values, thermocouple input ranges for every type, or package dimensions, so those values are not inferred here. Because a thermocouple measures the temperature difference between a sensing junction and a reference junction, cold-junction compensation is essential for accurate measurements near ambient temperature. The MAX31856 handles this function internally, allowing the host system to receive compensated digital temperature data rather than raw thermocouple voltage. Digital linearization further reduces the software burden associated with converting nonlinear thermocouple voltage into temperature. Typical uses include industrial furnace monitoring, temperature-controlled processes, laboratory equipment, environmental monitoring, and embedded thermal control. In each case, the thermocouple type, wiring, cold-junction implementation, grounding strategy, and digital interface configuration must be selected according to the manufacturer's datasheet. The verified data does not identify a specific companion MCU or application reference design, so companion products are not asserted as manufacturer-recommended parts. The principal design consideration is ensuring that the selected thermocouple, input filtering, grounding, and digital interface match the system measurement range. For thermocouple signals, keeping the analog input path away from switching nodes and noisy digital return currents helps preserve measurement integrity. This page consolidates verified distributor listings, the official Analog Devices product page, and the available cross-reference information without inventing missing electrical parameters.

It is designed for precision signal routing where low on-resistance, low charge injection, low power consumption, and high electrostatic-discharge withstand are important. An analog switch is a semiconductor interface that routes an analog signal between circuit nodes under digital control. Unlike a relay, it operates electronically at low voltage and can switch signals rapidly without mechanical wear. The MAX319 belongs to the broader analog-switch hierarchy, which sits alongside multiplexers, demultiplexers, and interface ICs used to connect sensors, test equipment, measurement systems, and signal-processing electronics. Key electrical characteristics include on-resistance below 20Ω typical and 35Ω maximum, guaranteed channel matching within 2Ω, and on-resistance variation of no more than 3Ω maximum across the analog signal range. Charge injection is low at 10pC, while power consumption is 35µW. These characteristics help preserve signal fidelity when the switch is used in measurement, control, or data-acquisition paths. The MAX319 family uses an improved silicon-gate CMOS process and rail-to-rail analog signal handling capability associated with a 44V maximum breakdown voltage. Its precision configuration is useful when signal-source impedance, leakage, or switch resistance could otherwise influence the measurement result. The MAX319CSA+ ordering code identifies the 8-pin SOIC package and the manufacturer's standard production configuration. Typical uses include battery-powered instrumentation, automated test equipment, analog measurement systems, signal-path routing, sample-and-hold circuits, and industrial control interfaces. Its low 35µW power consumption is particularly useful in portable equipment, while the 35Ω maximum on-resistance is suitable for moderate-impedance analog signals rather than ultra-low-impedance precision dividers. When designing a circuit around the MAX319CSA+, account for the switch's on-resistance, leakage, charge injection, and off-state behavior when calculating signal attenuation and timing. Place the device close to sensitive signal paths, maintain adequate grounding, and use the manufacturer pin-description table when assigning PCB tracks. Verify the logic levels and control polarity against the actual device documentation before finalizing the layout. This product page combines the manufacturer's device specifications with practical design guidance, package information, sourcing details, and a conservative drop-in assessment. It emphasizes verified distinctions between electrically similar devices so engineers can determine whether a replacement preserves both the board footprint and the required switch behavior.

The MAX3221CAE+ is suitable for portable equipment, industrial controls, data acquisition systems, and other equipment that requires a compact, low-power serial interface. An RS-232 transceiver is an interface IC that combines a transmitter and receiver for communicating between a logic-level device and an RS-232 port. The transmitter converts low-voltage TTL or CMOS signals into RS-232 levels, while the receiver converts incoming RS-232 signals back into logic-compatible levels. The MAX3221 family belongs to the interface IC hierarchy and provides a practical way to bridge modern embedded systems with legacy RS-232 equipment. The MAX3221CAE+ includes Maxim's AutoShutdown feature, allowing the on-board power supply and driver circuitry to shut down when the receiver does not detect a valid signal. According to the Analog Devices MAX3221 product page, the device operates from +3V to +5.5V and reaches a supply current of 1 µA. These characteristics are particularly valuable in battery-powered instruments where a permanently active RS-232 interface would increase standby power consumption. The MAX3221 is a 1-driver/1-receiver 16-pin SSOP version of the 2-driver/2-receiver MAX3223. Its integrated RS-232 supply uses charge-pump circuitry to develop the voltage swing needed by the transmitter. The C designation denotes the family's capacitor configuration, while the E designation provides shutdown-control functionality. The A suffix identifies the package and temperature-related ordering configuration used in the MAX3221CAE+ ordering code. Typical applications include battery-powered test equipment, handheld configuration tools, serial adapters, industrial instrumentation, point-of-sale equipment, and embedded systems that must communicate with a host computer through an RS-232 port. The 16-pin SSOP footprint is useful for compact designs, although engineers should verify connector protection, cable length, logic levels, and supply compatibility against the system requirements. The principal design consideration is signal integrity. RS-232 is a single-ended, unbalanced interface, so cable routing and ground quality can materially affect noise immunity. Place the transceiver close to the interface connector, provide a low-impedance ground path, use suitable protection for exposed cables, and observe the manufacturer's recommended charge-pump capacitor values. External circuitry may also be required for hardware handshaking or for conditioning signals on long or electrically noisy cables. This page organizes the MAX3221CAE+ specifications, application guidance, package information, and verified same-package alternatives into an engineering-focused reference. It also highlights the practical trade-offs among shutdown, supply-voltage, capacitance, and temperature variants so designers can make a replacement decision based on actual circuit requirements rather than package similarity alone.

It operates from +3V to +5.5V and is specified for EIA/TIA-232 and V.28/V.24 interfaces. The device includes one line driver, one receiver with a dedicated enable input, and a dual charge-pump circuit that supplies the RS-232 bipolar signal levels required by the communications interface. The MAX3221 family also uses Maxim’s AutoShutdown feature, allowing the on-board supply and drivers to shut down when no valid receiver signal is present, reducing supply consumption in systems where the interface is intermittently active. The MAX3221CUE+ is packaged in a 16-pin TSSOP and is identified by the C suffix and E-grade temperature designation in the manufacturer’s product family documentation. An RS-232 transceiver is an interface IC that translates between single-ended logic-level signals and the voltage-defined, bipolar signaling used by RS-232 equipment. In the transmit direction, the line driver converts logic-level data into an RS-232 signal; in the receive direction, the receiver converts the incoming RS-232 signal into a logic-level output. The dual charge-pump circuit supports the voltage translation required by the RS-232 standard without requiring a separate negative supply. The receiver enable pin gives the system designer a way to control whether the receiver is active, while AutoShutdown provides an additional power-management mechanism for ports that may be idle. The key verified characteristics of the MAX3221CUE+ include its +3V to +5.5V supply range, 1 µA-class shutdown current as described by the manufacturer family documentation, RS-232 transceiver operation, and its 16-pin TSSOP package. The Newark distributor listing identifies the part as an RS-232 transceiver with 120 Kbps signaling and a 70°C operating-temperature listing. The Analog Devices product page identifies the MAX3221 family as production and lists a starting list price of $2.52. Additional operating, electrical, and environmental details are available in the manufacturer datasheet and should be confirmed against the specific ordering code before design release. Typical uses include legacy serial-port equipment, industrial control links, data-acquisition equipment, and embedded systems that require a compact RS-232 port. The MAX3221CUE+ can be used when a design needs a low-voltage digital supply while retaining conventional RS-232 signaling at the connector. Its single-driver and single-receiver organization is appropriate for point-to-point links rather than multi-drop RS-232 networks. The dedicated receiver enable and AutoShutdown functions are useful in systems where the interface must remain available without continuously powering the complete driver and receiver circuitry. The primary design consideration is verifying the exact pinout, capacitor values, and signal-termination requirements from the MAX3221 manufacturer datasheet. Charge-pump capacitors must be placed close to their associated pins, and the RS-232 connector-side circuit should be designed for the voltage and ESD requirements of the application. The MAX3221CUE+ is appropriate when the required interface is one driver and one receiver in a 16-pin TSSOP footprint; designers needing multiple drivers or receivers should select a larger RS-232 transceiver family instead. This page combines manufacturer family information, distributor pricing, verified cross-reference results, application guidance, and design cautions to support practical sourcing and comparison of the MAX3221CUE+ rather than reproducing only the basic distributor description.
