The Analog Devices MAX3385EEAP is a low-power RS-232 transceiver rated for data rates up to 250kbps and operation from a 3.0V to 5.5V supply. The device is offered in a 20-pin SSOP package and provides the driver and receiver functions required to connect a modern digital circuit to an RS-232 serial port. Its integrated protection is specified for ±15kV electrostatic-discharge exposure on the serial lines. An RS-232 transceiver is an interface IC that belongs to the line-driver and line-receiver hierarchy within interface semiconductors. It converts logic-level signals into RS-232-compatible levels in the transmit direction and converts incoming RS-232 levels back into logic levels in the receive direction. The MAX3385EEAP therefore provides the physical signaling layer between equipment logic and a cable-based serial interface. Key characteristics include support for both 3.0V and 5.5V supply operation, a maximum signaling rate of 250kbps, low-power design, true RS-232 transceiver operation, and ±15kV ESD protection. The 3.0V minimum supply makes the interface suitable for systems whose digital core operates below 5V, while the 5.5V upper limit allows use with conventional 5V equipment. The 250kbps rate supports modern point-to-point serial links without requiring the lower bandwidth associated with legacy communication standards. The MAX3385EEAP combines two transmit drivers and two receive receivers in one package, matching the conventional direction and signal arrangement used by RS-232 interface designs. Its integrated ESD protection reduces the amount of external protection normally required at a connector or cable entry. Applications still require correct signal routing, suitable bypass capacitance, controlled return paths, and compliance with the applicable RS-232 electrical requirements. Typical uses include industrial control consoles, test equipment, data acquisition systems, service interfaces, and embedded products that retain an RS-232 port for configuration or diagnostics. The part is particularly useful where modern 3.3V logic must communicate with an RS-232 host while board area and external protection components must be minimized. Designers should begin with the manufacturer's pin-description table when assigning PCB tracks and must preserve the documented charge-pump and driver topology around the transceiver. Input and supply bypassing should be placed close to the relevant pins, and connector-side protection must be reviewed against the required ESD exposure and working voltage. This page consolidates the core electrical and package characteristics of the MAX3385EEAP with application guidance, comparison parameters, and practical interface-design considerations. It is intended to help engineers determine whether the device's voltage range, data rate, package, and protection level match a particular RS-232 design before committing the footprint to a PCB.

The MAX3386ECUP+ supports a 3.0V to 5.5V supply and operates at data rates up to 250kbps while maintaining RS-232-compliant output levels. Its dual charge pump requires four 0.1uF capacitors for operation from a 3.3V supply. The three-driver, two-receiver arrangement suits equipment with several outbound serial channels and fewer inbound channels, while enhanced electrostatic-discharge protection improves robustness in exposed cable-connected systems. The low-dropout transmitter output stage enables true RS-232 performance without requiring a 5V-only power rail, making the device useful in battery-powered and portable systems. The manufacturer describes the MAX3386E family as a low-power communications interface with high data-rate capability and enhanced ESD protection. Charge-pump switching and transmitter edge behavior should be considered when the serial link operates next to sensitive analog circuitry. Typical uses include RS-232 ports in personal digital assistants and cellular phones, diagnostic and programming interfaces, industrial equipment, point-of-sale terminals, and embedded serial adapters. Its 250kbps maximum rate provides useful margin above common asynchronous serial communication rates, while the compact 20-pin TSSOP package supports space-constrained portable products. Design the charge-pump capacitor network for the shortest practical connection to the supply and ground pins. Confirm the connector-side protection strategy and cable routing because the integrated ESD protection does not eliminate the need for correct board layout and system-level grounding. Verify signal levels and timing against the manufacturer datasheet before replacing a multi-transceiver interface. This product page combines manufacturer specifications, pin-compatible alternatives, application guidance, and practical interface-design notes. It helps engineers compare protocol capability, package compatibility, protection, and implementation constraints before selecting a compact RS-232 transceiver.

Typical applications include personal digital assistants, cellular phones, portable instrumentation, barcode readers, industrial controls, and service or diagnostic equipment. It is particularly useful where a compact PCB requires several RS-232 signals but the system power supply operates near 3V. The interface supports point-to-point links rather than multidrop RS-232 networks. When designing the circuit, account for RS-232's unbalanced voltage signaling and use a suitable protection network at any externally accessible connector. Keep the transceiver and its charge-pump components away from sensitive analog areas, and follow the Analog Devices pin-description table when assigning connector and logic signals. Confirm the exact data rate, supply range, and operating temperature limits against the manufacturer datasheet before release. This page combines the manufacturer's interface description, package information, drop-in candidates, application guidance, and design considerations to support faster component evaluation and sourcing decisions.

Typical applications include RS-232 links in PDAs, cellular phones, data acquisition equipment, industrial controllers, point-of-sale terminals, and portable diagnostic instruments. The three-transmitter and three-receiver organization is useful where a board must expose multiple serial channels while conserving space and avoiding separate level-conversion ICs. Design should place the charge-pump capacitors close to their designated pins and route each RS-232 driver output with controlled return-path geometry. External protection may still be required for long cables or severe industrial environments, and system designers should confirm logic levels, shutdown behavior, receiver enable timing, and line-driver loading against their system requirements. This page organizes the principal electrical characteristics, package information, verified sourcing references, compatible family options, and practical interface-design considerations into a consolidated guide for engineers evaluating the MAX3387ECUG+.
MAX3387EEUG+ - 3V RS-232 Transceiver, 250kbps, ±15kV ESD | Maxim
The Analog Devices (formerly Maxim Integrated) MAX3387EEUG+ is a 3V-powered, ±15kV ESD-protected RS-232 transceiver with three drivers and three receivers, housed in a 24-pin TSSOP package. It supports data rates up to 250 kbps, complies with EIA/TIA-232 and V.28/V.24 standards, and integrates a charge pump to generate the ±5.5V RS-232 levels from a single 3.0V to 5.5V supply. The 'E' suffix indicates the enhanced AutoShutdown Plus mode that reduces supply current to 1 µA typical when no valid cable is connected. An RS-232 transceiver is a line driver/receiver IC that translates between TTL/CMOS logic levels (0-3.3V) on the UART side and the bipolar ±5V to ±15V signal levels required by the legacy RS-232 standard on the cable side. RS-232 transceivers sit at the physical layer of serial communication and remain ubiquitous in point-of-sale terminals, industrial equipment, legacy PC peripherals, and embedded debug ports despite being superseded by USB and Ethernet in many consumer applications. Key features include ±15kV ESD protection on the RS-232 bus pins (IEC 61000-4-2 Air Gap), an integrated dual charge pump requiring only four small 0.1µF external capacitors, and an AutoShutdown Plus mode that automatically disables the charge pump and receivers when the cable is disconnected. The device operates from a single 3.0V to 5.5V supply and includes three active-low INVALID outputs for system monitoring. The MAX3387EEUG+ uses a proprietary low-power charge pump architecture combined with Maxim's AutoShutdown Plus logic, achieving 1 µA typical supply current in shutdown while still supporting 250 kbps data rates. The dual charge pump generates +7V and -7V from the input rail using only flying capacitors, eliminating the need for a ±12V system supply. Typical applications include PDA and cell phone data cables, palmtop computers, battery-powered equipment, embedded industrial controllers, GPS receivers, and point-of-sale (POS) terminals. Its single-supply 3V operation makes it ideal for portable, battery-powered designs where ±12V rails are unavailable. When designing with this device, place the four charge-pump capacitors (typically 0.1µF ceramic) as close as possible to the C1+, C1-, C2+, and V+ pins. Ensure the ESD-protected bus traces are kept short and routed away from sensitive analog signals. For systems that can tolerate a slightly larger TSSOP, the MAX3387ECUG+ offers a commercial 0°C to +70°C temperature range as an alternative. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone.

These characteristics make the device suitable for portable equipment that must communicate with RS-232 peripherals while preserving a compact, low-voltage power architecture. The device's multi-driver arrangement allows several unidirectional RS-232 outputs alongside two receive channels, enabling asymmetric links such as command, control, status, and diagnostic paths. Its 24-pin TSSOP package provides a conventional surface-mount footprint that can simplify board layout relative to discrete driver and receiver implementations. Low-voltage operation also allows the IC to share a compact portable power rail without requiring a separate 5V interface supply. Typical applications include serial adapters for personal digital assistants, communication ports in cellular telephones, data acquisition equipment, industrial controllers, and portable test instruments. It is particularly appropriate where an equipment designer needs a compact EIA/TIA-232 interface, multiple logic-level outputs, receive inputs, and stronger ESD tolerance on externally accessible serial lines. When laying out a design, keep the transceiver's logic-side traces away from the exposed RS-232 connector and route driver outputs as short, direct connections to the interface pins. Confirm the connector's signal polarity and the logic-level relationship of the connected UART before using each driver and receiver, because the RS-232 electrical standard is not directly compatible with ordinary CMOS signals. This page combines the device's interface functions, RS-232 operating characteristics, verified package information, sourcing guidance, and application-focused design guidance to support faster component selection and implementation. For a replacement, verify the exact suffix, pin assignment, electrical ratings, and system-level RS-232 polarity before production release.
MAX3389ECUG+ - 2.5V 3/2 RS-232 Transceiver | ADI
Analog Devices MAX3389ECUG+ is a 3-driver, 2-receiver RS-232 transceiver designed for low-voltage serial-interface systems. It operates from a 2.5V supply, supports the EIA/TIA-232 and V.28/V.24 communication standards, provides ±15kV ESD protection on its external interface pins, and is packaged in a 24-pin TSSOP. The device targets portable and mobile equipment requiring a compact, low-power RS-232 interface. An RS-232 transceiver is an interface IC that converts logic-level signals between a host or controller and a cable-based RS-232 link. The MAX3389ECUG+ combines three transmit channels with two receive channels in one package. This mixed 3/2 configuration allows one controller to command three external targets while receiving status or data from two of them, reducing the number of separate interface components required in portable equipment. The primary electrical features are the 2.5V operating supply, a specified 2.35V to 3V transceiver supply range, and ±15kV ESD protection. These characteristics make the device suitable for systems in which connector exposure, limited battery energy, and restricted board area are important design constraints. The enhanced ESD protection helps improve interface robustness when users connect external cables to personal digital assistants, mobile phones, and other handheld communications products. The MAX3389 family implements the electrical signaling required by EIA/TIA-232 and V.28/V.24 interfaces. Driver channels convert TTL-compatible command signals into RS-232 levels, while receiver channels recover RS-232 data as logic-level signals. The integrated multi-channel arrangement also reduces the number of package outlines and PCB land patterns that a design team otherwise needs to manage for several independent serial ports. Typical uses include personal digital assistant connectivity, mobile phone accessories, handheld test equipment, point-of-sale terminals, and compact industrial controllers. The low 2.5V supply requirement allows the interface to operate alongside low-voltage logic, while the TSSOP-24 package supports compact board layouts. Product qualification, ordering, and lifecycle requests can be handled through the Request a Quote form on this page. The primary design consideration is external-signal handling. Although the device has enhanced ESD protection, the board still needs a suitable return path, controlled cable routing, and connector placement that minimizes ESD exposure. Power and signal integrity should be evaluated together because the RS-232 drivers and receivers operate at a higher voltage domain than many modern low-voltage host controllers. This page combines the identified electrical ratings, package information, application context, comparison parameters, and practical design guidance into one engineering reference. It also distinguishes exact drop-in candidates from related interface families and highlights which characteristics must still be confirmed in the manufacturer datasheet before a substitution is released to production.
MAX338CEE+ - 8:1 Low-Leakage CMOS Analog Mux | Analog Devices
The Analog Devices MAX338CEE+ is an 8-channel, low-leakage CMOS analog multiplexer with a 1 Circuit 8:1 configuration, 400 ohm on-resistance, and a 16-QSOP package. According to the manufacturer product data, the device connects one of eight inputs to a common output, making it suitable for routing external analog signals in test, measurement, control, and communication systems. The verified listing identifies a single +4.5 V to +30 V supply or dual supplies of ±4.5 V to ±20 V. An analog multiplexer is an analog switch device that selects one signal path among multiple inputs and connects it to a shared output. The MAX338 family is positioned as a low-leakage CMOS analog multiplexer family, with the MAX338 providing eight channels and the related MAX339 providing dual four-channel operation. This hierarchy places the part within analog switches, multiplexers, interface ICs, and broader signal-routing systems. The verified MAX338CEE+ data specifies 400 ohm on-resistance and an 8:1 topology. Analog Devices identifies the MAX338 and MAX339 as pin-compatible upgrades for the industry-standard DG508A and DG509A families. The low-leakage characteristic is useful when source impedance is high, because leakage through an inactive channel can otherwise create measurement errors or interfere with small-signal nodes. The device also supports both single-supply and dual-supply operation, allowing integration into systems with different reference and bias arrangements. Typical uses include data acquisition, automated test equipment, sensor multiplexing, analog signal routing, sample-and-hold systems, and industrial control interfaces. The 8:1 arrangement reduces the number of physical connections required when a controller must inspect several analog sources through one downstream converter or measurement channel. Designers should verify signal amplitude, supply polarity, control logic, switching timing, and package footprint against their particular system before production use. A key design consideration is keeping unused analog inputs, control pins, and supply rails within the manufacturer's specified operating limits. PCB routing should minimize trace resistance and capacitance around high-impedance signal nodes, while grounding and decoupling should follow the datasheet recommendations. This page summarizes verified product, distributor, and manufacturer information; application suitability still depends on the complete electrical specification set.
MAX338CPE+ - 8:1 CMOS Analog Multiplexer | Analog Devices
The Analog Devices MAX338CPE+ is a single 8:1 CMOS analog multiplexer with 16-pin PDIP packaging, a 400 ohm on-resistance listing, and operation from a single 4.5 V to 30 V supply. It can also operate from dual supplies of ±4.5 V to ±20 V, making it suitable for instrumentation, industrial signal-routing, and test systems that require routing one of eight analog inputs to a common output. The chipdig listing also identifies the device as an 8-channel, low-leakage CMOS analog multiplexer with a 650 ohm resistance specification, so engineers should verify the applicable on-resistance condition against the manufacturer datasheet for their exact supply and temperature configuration. An analog multiplexer is a semiconductor switch that connects one selected input channel to a shared output. The MAX338CPE+ belongs to the CMOS analog switch and multiplexer hierarchy, where low-leakage CMOS construction supports high-impedance measurement circuits. Its 8:1 configuration reduces the number of physical input connections required when a controller must inspect several voltage, sensor, or diagnostic signals sequentially. The common output can then feed an ADC, measurement instrument, amplifier, or further signal-processing stage. Key features include eight selectable analog inputs, a single-ended common output, and a single 16-pin PDIP package. According to the Analog Devices MAX338 product page, the MAX338 and MAX339 devices are improved multiplexers that are pin-compatible upgrades for the industry-standard DG508A and DG509A families. The MAX338 family also supports both single and dual power-supply arrangements. These features distinguish it from multiplexer products that require one supply rail only or provide a different channel-to-pin arrangement. The MAX338CPE+ is a monolithic CMOS device intended to route low-frequency analog signals. Its channel count, supply range, and legacy DIP footprint are particularly useful when creating test fixtures, sensor interfaces, process-control equipment, or diagnostic systems that need to remain compatible with an existing 16-pin design. Because the common output carries the selected channel, the source impedance, signal amplitude, settling behavior, and downstream input range remain important system-level considerations. Typical uses include eight-way sensor selection, automated test equipment, industrial control signal routing, laboratory measurement systems, and instrumentation with multiple analog sources. The same-package DG508A and DG509A reference points are also useful when evaluating a design that was originally built around those established multiplexers. The MAX339 provides a related 4:1 dual-channel function rather than the MAX338's single 8:1 arrangement. When laying out the circuit, place the multiplexer close to the source and destination analog paths to minimize parasitic capacitance and resistance. Keep high-impedance traces short, provide a stable supply reference, and avoid excessive loading on the common output. Engineers should also confirm the exact channel pin assignments, control truth table, electrical limits, and operating-temperature grades in the manufacturer datasheet before treating the part as a production drop-in replacement. This page consolidates verified manufacturer and distributor information, supply configurations, package details, drop-in references, and practical selection guidance. It distinguishes documented pin-compatible alternatives from broader functional equivalents so procurement and engineering decisions can be made without confusing a multiplexer upgrade with a merely similar switch.
MAX338CSE+ - 8-Channel CMOS Analog Multiplexer | Maxim
The Maxim Integrated (now part of Analog Devices) MAX338CSE+ is a monolithic CMOS 8:1 analog multiplexer (also configurable as a dual 4:1) housed in a 16-pin narrow-body SOIC (NSOIC) package. It is built to route one of eight single-ended analog inputs to a common output under control of a 3-bit binary address, with on-resistance (RON) of 400 ohm typical over the full signal range. What is an analog multiplexer? An analog multiplexer (MUX) is a semiconductor switch that selects one of N analog input channels and routes it to a single output line, allowing a microcontroller or ADC to "scan" many sensors or signals through a single high-performance analog front-end. Multiplexers belong to the larger family of analog switches and are foundational building blocks in data acquisition, instrumentation, audio routing, and test equipment. The MAX338 operates from a single +4.5V to +30V supply (or dual ±4.5V to ±20V supplies), giving designers wide headroom for industrial 24V rails and ±15V instrumentation racks. Key features include low-leakage CMOS construction (typically < 1 nA at room temperature), break-before-make switching action that prevents momentary channel cross-connection, ESD protection on all logic and analog pins, and pin-compatibility with the industry-standard DG508A / DG509A, enabling direct drop-in upgrade to lower leakage. Logic inputs are TTL/CMOS compatible, simplifying interface to 3.3V and 5V microcontrollers. The MAX338 is fabricated on a low-leakage dielectric-isolation CMOS process that minimizes parasitic capacitance and channel-to-channel charge injection. Internal logic-level translation allows the digital inputs (A0, A1, A2, EN) to be driven directly from modern microcontrollers. The device is specified over the commercial 0C to +70C temperature range, making it well suited for indoor test equipment and laboratory instrumentation rather than industrial or automotive use; for extended temperature ranges see the MAX338E variant. Typical applications include data-acquisition front-ends scanning multiple thermocouples or analog sensors, audio signal routing in mixing consoles and broadcast equipment, automated test equipment (ATE) pin boards, instrumentation multiplexer and sample-and-hold front ends, industrial process control signal multiplexing, and medical patient-monitoring analog front ends. Designers choose it when they need more analog inputs than their ADC provides and require clean, low-leakage switching. When designing with this device, place 0.1uF decoupling capacitors close to V+ and V- (or GND for single-supply use) and keep analog traces short to minimize crosstalk. Ensure all unused digital and analog inputs are tied to a defined logic level (not left floating) to prevent channel-to-channel leakage paths. This page synthesizes distributor pricing, drop-in alternatives, application guidance, and pin-level design notes that complement the manufacturer datasheet.
MAX338EEE+ - 8:1 Low-Leakage CMOS Multiplexer | Maxim Integrated
The Maxim Integrated MAX338EEE+ is an 8:1 low-leakage CMOS analog multiplexer with 400 ohm on-resistance, supplied in a 16-QSOP surface-mount package. It connects one of eight inputs to a common output and operates from a single +4.5 V to +30 V supply or from dual ±4.5 V to ±20 V supplies. The MAX338 family also includes dual 4-channel configurations for designs requiring two independently selected signal paths. An analog multiplexer is a semiconductor switching network that routes one selected input to a shared output. The MAX338 belongs to the CMOS analog switch and multiplexer hierarchy, where low leakage is valuable when measuring weak, high-impedance signals or when unused channels must contribute little error to the measurement system. It also supports positive-only and split-supply analog systems, allowing the same switching architecture to serve instrumentation, test, measurement, and signal-routing equipment. Verified product information identifies one analog switch circuit, an 8:1 configuration, 400 ohm on-resistance, a 16-QSOP package, and low-leakage CMOS construction. The single-supply operating range is +4.5 V to +30 V, while dual-supply operation extends from ±4.5 V to ±20 V. These wide ranges permit use with legacy ±15 V analog circuits as well as modern single-rail systems. The EEE ordering code is associated with the industrial-grade 16-terminal surface-mount variant shown in distributor data. Because the MAX338 is a monolithic CMOS multiplexer, its internal channels share one common output. This architecture minimizes the number of external signal paths in a multi-source measurement design, although it does not provide simultaneous access to all eight channels. Selection should therefore be based on required channel count, acceptable on-resistance, leakage limit, supply topology, and the voltage and current levels present at each switched node. Detailed leakage, bandwidth, charge-injection, and switching-time figures were not supplied in the verified excerpts and must be taken from the manufacturer datasheet. Typical uses include automated test equipment, data-acquisition systems, sensor-signaling interfaces, process-control instrumentation, and laboratory measurement front ends. The device is particularly useful when many potential analog inputs must share one amplifier, converter, or data-acquisition channel. A suitable external circuit must also keep every input and output within the device's absolute maximum ratings during switching and fault conditions. Designers should verify control logic levels, input overvoltage tolerance, analog signal range, and break-before-make behavior against the full datasheet before layout release. Care should be taken around unused channels, signal-source impedance, and injected charge because low leakage alone does not guarantee low measurement error. Input filtering may be appropriate when fast transients or high-energy events are possible. This product record combines verified manufacturer and distributor information, explicit data-gap markers, same-family drop-in candidates, and practical selection guidance. It is intended to help engineers identify the correct 16-QSOP multiplexer while separating confirmed MAX338EEE+ attributes from parameters that still require direct datasheet verification.
MAX338EEE+T - 8:1 CMOS Analog Multiplexer | Maxim Integrated
Maxim Integrated MAX338EEE+T is an 8:1 single-ended CMOS analog multiplexer with 400 ohm on-resistance, housed in a 16-pin SSOP package. It selects one of eight analog inputs and connects the selected input to a common output. The device operates from a single +4.5 V to +30 V supply or from dual supplies of ±4.5 V to ±20 V, making it suitable for both positive-rail and split-supply instrumentation. An analog multiplexer is an interface IC that routes multiple analog signals through one common connection. The MAX338 belongs to the CMOS analog switch family, combining an 8:1 multiplexer with low-leakage switching elements. This allows a measurement system, data-acquisition circuit, or industrial control board to reduce the number of dedicated signal paths while preserving accurate analog connectivity. The principal features include an 8:1 configuration, 400 ohm on-resistance, and 20 pA leakage. Its address and enable controls are TTL-compatible from +0.8 V to +2.4 V across the specified temperature and supply ranges. These characteristics make the device useful when a system must select among sensor outputs, measurement inputs, or multiplexed test points without using a separate connector for every channel. The MAX338 is fabricated using Maxim's 44 V silicon-gate process, supporting operation with relatively wide supply voltages. The manufacturer identifies the MAX338 and MAX339 as improved, pin-compatible upgrades for the industry-standard DG508A and DG509A. Related MAX328 and MAX329 devices provide lower leakage and charge injection but higher on-resistance, creating a useful trade-off between leakage, switching transients, and signal resistance. Typical applications include data-acquisition systems, automated test equipment, industrial process monitoring, medical instrumentation, and communication-interface boards. An eight-channel bank can route eight analog sources into one amplifier, comparator, or converter input, while complementary address and enable logic controls the selected path. The industrial temperature grade also supports equipment intended for factory, laboratory, and communications environments. PCB design should place input and output traces away from high-speed digital paths, provide a stable ground reference, and observe the supply and decoupling requirements in the manufacturer datasheet. Because the multiplexer contributes 400 ohm of series resistance and switching transients, the receiving amplifier should have sufficiently high input impedance and bandwidth. Fault conditions should also be checked with the device disabled so that unused inputs cannot create unintended loading or signal transitions. This product page combines manufacturer specifications, package information, functional context, replacement guidance, and application-oriented design guidance. It helps engineers evaluate the MAX338EEE+T against same-package family options while accounting for channel configuration, on-resistance, leakage, and control-interface compatibility.

The device connects one of eight inputs to a common output, making it suitable for analog signal routing in instrumentation, test systems, data acquisition, and embedded control equipment. Verified distributor data identifies the MAX338EPE+ as a single-circuit IC switch, 8:1 multiplexer, 400 Ω switch, and 16-pin DIP package; the Analog Devices product page describes the MAX338 family as a monolithic CMOS analog multiplexer. An analog multiplexer is a switching semiconductor that routes multiple analog inputs to one shared signal path under digital control. The MAX338/MAX339 family belongs to the analog switch and mux hierarchy, where the MAX338 provides one 8-channel single-ended path and the MAX339 provides dual 4-channel operation. Reducing the number of external signal connections can simplify wiring, board space, and system architecture when several sensors or measurement nodes must be selected by a controller. Key verified characteristics include an 8:1 configuration, 400 Ω on-resistance, 16-PDIP mechanical package, industrial temperature grade, and through-hole mounting. The MAX338EPE+ uses a 3-bit binary address to select one of eight inputs according to the manufacturer description. The verified snippets do not provide complete electrical limits such as supply voltage, leakage current, bandwidth, switch capacitance, or logic thresholds, so those values must be checked against the official manufacturer datasheet before final design release. The MAX338 family is positioned for low-leakage CMOS analog multiplexing. This makes the device relevant where a controller must scan multiple analog sources while preserving a common signal-conditioning path. The common output can feed a downstream amplifier, ADC, comparator, or measurement front end, while the selected address determines which input reaches that shared node. The exact input signal range and allowable switching conditions depend on parameters not included in the verified search snippets. Typical uses include multimeter and bench-test input selection, sensor-channel scanning, industrial control interfaces, data-acquisition systems, and embedded measurement modules. The 16-PDIP package favors through-hole prototyping and repair rather than compact surface-mount production. Because the available evidence does not provide full timing, power, and absolute-maximum ratings, engineers should use the official MAX338 datasheet and validate signal levels, supply rails, leakage, settling behavior, and control timing in the intended system. A key design consideration is ensuring that the downstream circuit can tolerate the mux's on-resistance, leakage, and charge injection. Signal-chain errors become more significant when source impedance is high, source-to-source voltage differences are large, or measurement accuracy is dominated by leakage. Route the selected output with short traces, maintain a stable reference and supply arrangement, and account for control-signal timing before sampling the analog node. This page combines verified distributor listings, the Analog Devices family description, package information, and practical selection guidance for engineers evaluating the MAX338EPE+.

MAX338ESE+ - 8:1 Low-Leakage CMOS Analog Multiplexer | Maxim Integrated
The Maxim Integrated MAX338ESE+ is an 8-channel, low-leakage CMOS analog multiplexer packaged in a 16-pin narrow SOIC, with a maximum on-resistance of 400 ohm and a single-supply operating range of +4.5V to +30V (or dual supplies of +/-4.5V to +/-20V). The device is pin-compatible with the industry-standard DG508A and DG509A, and the ESE suffix denotes the extended temperature (-40C to +85C) 16-SOIC package. An analog multiplexer, or mux, is a semiconductor switch that routes one of several analog input channels to a shared output node under digital address control. It sits in the signal path between sensors, amplifiers and converters on one side and a single measurement or processing chain on the other. In the broader hierarchy, MAX338ESE+ belongs to the analog switch and multiplexer family, which in turn falls under interface ICs within integrated circuits. Reducing eight or sixteen analog wires down to one shared node is the core value proposition: fewer PCB traces, fewer connector pins, and a smaller multiplexing front end for data acquisition. Key features include a 400 ohm maximum on-resistance, low off-state leakage, and bidirectional analog channels, so the mux can be used as either a multiplexer or a demultiplexer. The device runs from a single +4.5V to +30V rail or from dual rails of +/-4.5V to +/-20V, which makes it suitable for both modern low-voltage instrumentation and legacy +/-15V or +/-12V analog test equipment. Fault-protected channel architecture improves robustness when inputs are over-driven or switched while signals are present. Internally the MAX338 uses CMOS transmission-gate switches driven by a 3-bit binary address for the 8-channel configuration, with the address decode and drive circuitry integrated on the same die. Because the channels are bidirectional, the same silicon supports demultiplexing applications where the single common node is driven and the eight channel nodes are the destinations. This symmetry is what allows one part number to cover both directions of analog routing. Typical applications include multi-channel data acquisition systems, automated test equipment, process-control instrumentation, multimeter and measurement front ends, battery and power-supply test systems, and data logger signal conditioning. Designers frequently use the MAX338 alongside RS-232 and RS-485 transceivers, parallel interface controllers, and precision amplifiers to build compact measurement instruments. The main design consideration is supply headroom and signal range: because the channels are bidirectional and the on-resistance is relatively high at 400 ohm, the device is best suited to high-impedance sources and precision measurement nodes rather than low-impedance power or current-carrying loads. Check the injected charge and off-state leakage against your accuracy budget. This page consolidates manufacturer documentation, distributor pricing and availability, pin-compatible drop-in alternatives, and practical layout guidance so engineers can evaluate a redesign or a second-source sourcing decision without pulling together five separate documents.
MAX338ESE+T - 8:1 CMOS Analog Multiplexer | Analog Devices
Analog Devices MAX338ESE+T is an 8:1 CMOS analog multiplexer with 400 ohm on-state resistance, housed in a 16-SOIC package. The device operates from a single +4.5 V to +30 V supply or from dual supplies of ±4.5 V to ±20 V, and its TTL-compatible address and enable inputs support both 5 V and high-voltage control environments. An analog multiplexer is an analog switch that routes one of several input signals to a shared output. The MAX338 belongs to the broader hierarchy of CMOS analog switch, multiplexer, interface IC, and semiconductor devices. Its eight channels are selected by a 3-bit binary address, while an enable input provides control over the selected connection. The device can therefore operate as a multiplexer or serve as a demultiplexer when the direction of signal routing is reversed. The MAX338/MAX339 family uses Maxim's 44 V silicon-gate process. This process supports operation from a single +4.5 V to +30 V supply or from dual ±4.5 V to ±20 V supplies. All address and enable controls remain TTL-compatible over their specified ranges, with a +0.8 V to +2.4 V input threshold identified for the control inputs. These characteristics make the multiplexer suitable for systems that must route wide-range analog signals. The 400 ohm on-state resistance identifies the MAX338 as a low-leakage CMOS multiplexer option intended for precision signal routing rather than high-current power switching. Its eight-to-one configuration reduces the number of physical connections required when several measured or conditioned signals must reach one processing channel. The common output architecture can also simplify board routing when a controller selects among sensor, instrument, or test-point signals. Typical applications include automated test equipment, data-acquisition systems, instrumentation, industrial control, and measurement setups. In each case, the 3-bit address bus identifies the desired channel and the enable input controls whether the common output is connected. The part is particularly useful where one analog input must be presented to a shared amplifier, converter, or measurement circuit without duplicating that downstream circuitry. A key design consideration is that the MAX338 is not a power switch. Its 400 ohm on-state resistance contributes signal attenuation and, when driving a finite load, can introduce an interaction between switch resistance and downstream input impedance. Layout should keep analog traces short, maintain a stable return path, and avoid placing high-current switching nodes near the selected input channels. This page consolidates the manufacturer's supply-range information, package details, functional characteristics, verified alternatives, and practical routing guidance into an engineering-focused guide for selecting and implementing the MAX338ESE+T in high-voltage analog multiplexing systems.

The device connects one of eight inputs to a common output using a 3-bit binary address, making it suitable for analog signal routing, measurement systems, instrumentation, and control equipment. An analog multiplexer, or analog mux, is an interface IC that routes one selected input channel to a shared output while blocking unselected channels. The MAX338 is a monolithic CMOS device intended for low-leakage signal-path applications. Its 8:1 configuration reduces the number of external signal lines when a system must select among multiple sensors, sources, or measurement channels. The 400 Ω specification is identified by the verified distributor listing, while additional electrical limits are not supplied in the retrieved data and are therefore not inferred here. The key verified feature set includes an 8:1 configuration, 400 Ω on-resistance, low-leakage operation, CMOS construction, and a 16-TQFN 5 x 5 mm package. The manufacturer describes the MAX338 family as connecting one of eight inputs to a common output through a 3-bit binary address. The single-pole, single-throw switching arrangement is represented by the 8:1 mux function, although detailed break-before-make and charge-injection values were not provided in the verified snippets. This part is useful when the system must share a downstream amplifier, ADC, DAC, or measurement block across several analog sources. It can help simplify routing in data-acquisition systems, sensor interfaces, automated test equipment, industrial controllers, and communication equipment. The low-leakage characteristic is particularly relevant when source impedance is high or when leakage can affect measurement accuracy, although the exact leakage limit should be confirmed in the manufacturer datasheet. The 16-TQFN package supports compact surface-mount layouts and requires careful PCB design around the exposed-pad and thermal requirements shown in the manufacturer documentation. A key design consideration is to verify signal voltage, supply voltage, input impedance, switching speed, and leakage against the complete MAX338 data sheet before production release. The verified distributor data confirms the part number and package, but does not provide a complete set of timing, current, or absolute-maximum ratings. This product page combines the verified manufacturer identification, distributor package data, pricing references, and application guidance. It also distinguishes confirmed parameters from values requiring datasheet confirmation, helping engineers make an informed sourcing decision without introducing unsupported specifications.
MAX338ETE+T - 8:1 CMOS Analog Multiplexer | Analog Devices
Analog Devices MAX338ETE+T is a single 8:1 CMOS analog multiplexer with 400 ohm on-resistance, housed in a 16-TQFN package with a 5 x 5 mm footprint. It operates from a single +4.5V to +30V supply or from dual supplies of ±4.5V to ±20V. Its TTL-compatible address and enable inputs accept logic levels from +0.8V to +2.4V across the specified temperature range. An analog multiplexer is an analog switch that routes one of several input signals to a shared output. A single 8:1 multiplexer provides eight selectable signal paths while reducing the number of external connections required between a source circuit and a measuring or processing circuit. The MAX338 is designed for precision signal-routing requirements and is fabricated using Maxim's 44V silicon-gate process. The primary function is an 8:1 single-ended analog switch. Its specified 400 ohm on-resistance makes it suitable for routing moderate-impedance sensor, measurement, or control signals rather than high-current loads. TTL-compatible control inputs simplify connection to 5V CMOS and TTL control logic. Operation from either a single positive supply or dual supplies also supports systems that use positive-only or bipolar analog rails. The MAX338 family is fabricated on a 44V silicon-gate process, providing the voltage headroom needed for the specified operating ranges. The manufacturer describes the MAX338 as a low-leakage CMOS analog multiplexer. Its improved multiplexing performance is intended to address both leakage and charge-injection considerations when selecting among analog sources, although exact device-level values should be confirmed in the manufacturer datasheet. Typical applications include sensor-signal selection, data-acquisition front ends, instrumentation, industrial control, test and measurement equipment, and analog signal routing in systems operating from a single +5V rail or higher single-supply rails. The eight-to-one configuration is especially useful when a system must select among multiple analog inputs before conversion, amplification, comparison, or further signal conditioning. When designing around the MAX338ETE+T, verify the exact supply limits, control-logic states, analog signal range, switch configuration, and exposed-pad connection against the manufacturer datasheet. Place the device so its thermal pad can dissipate heat as intended, keep sensitive analog routing away from fast-switching nodes, and account for off-state leakage and channel charge injection in high-impedance precision circuits. This product page consolidates the MAX338ETE+T manufacturer specifications, verified product identifiers, source links, application guidance, design considerations, and qualified replacement information. It is structured to help engineers move from datasheet lookup to footprint-compatible sourcing without treating different package or electrical variants as interchangeable.
MAX338MSE/PR3+ - 8:1 CMOS Multiplexer | Analog Devices
Analog Devices MAX338MSE/PR3+ is a single 8:1 CMOS analog multiplexer with 400 ohm on-resistance, a 3-bit binary address interface, and a 16-pin SOIC package. It connects one of eight inputs to a common output and can also operate as an eight-channel demultiplexer by reversing the signal-routing role. The low-leakage architecture is intended for precision analog-signal selection systems where minimizing off-state coupling is important. An analog multiplexer is a semiconductor switch that routes one of several physical input channels to a shared signal path. It belongs to the analog switch and multiplexer hierarchy, interface IC category, and broader signal-conditioning system. Unlike a digital multiplexer, its primary purpose is to preserve analog signal integrity while selecting a source for measurement, conversion, instrumentation, or communication circuitry. The MAX338 family provides eight selectable channels in the MAX338 configuration and uses address logic to determine which input reaches the common output. Its 400 ohm on-resistance is suitable for many medium-impedance sensor and instrumentation nodes. The CMOS implementation, low-leakage characteristic, and analog switching function make the device useful when channel isolation and signal routing matter more than very high bandwidth or very low resistance. Three address-control bits select one of eight possible input paths. The selected signal can be used in either multiplexing or demultiplexing arrangements, allowing the same device family to support measurement systems, signal-distribution networks, and test systems. The exact electrical limits, address timing, channel characteristics, supply requirements, and operating-temperature limits must be confirmed in the Analog Devices MAX338 manufacturer data sheet before finalizing a circuit. Typical uses include multiplexing resistive sensor outputs into an analog-to-digital converter, selecting instrumentation channels, routing multiple test points through a shared measurement chain, and building compact signal-distribution systems. These applications benefit from the dedicated 8:1 topology and the low-leakage CMOS design. Designs requiring substantially lower on-resistance, faster switching, higher voltage operation, or differential channel handling may need a different multiplexer family. When laying out a board, route the eight analog inputs and common output as short, guarded traces, place the device close to the sensing circuitry, and keep digital address lines away from sensitive analog paths. Confirm the package pin arrangement and the manufacturer’s grounding and supply recommendations on the official data sheet. Do not infer pin functions from another MAX338 package or ordering code without checking the exact pin description table. This product summary combines the official MAX338 family description, package and routing information, temperature-code context, and application-focused engineering guidance. It also identifies the package-compatible alternatives that can be evaluated without changing the PCB footprint and highlights the principal trade-offs between low-leakage multiplexing, switching resistance, and system flexibility.
MAX338MSE/PR3+T - 8:1 CMOS Multiplexer | Analog Devices
Analog Devices MAX338MSE/PR3+T is an 8-channel or dual 4-channel CMOS analog multiplexer with a 400 ohm on-resistance, packaged in a 16-SOIC. The device connects one of eight inputs to a common output, providing low-leakage signal routing for test, measurement, control, and data-acquisition systems. It can operate from a single +4.5 V to +30 V supply or from dual supplies of ±4.5 V to ±20 V. An analog multiplexer is a semiconductor switch that routes multiple analog inputs through a shared output path. The MAX338 belongs to the broader interface-IC hierarchy: analog multiplexer, analog switch, interface IC, and semiconductor. Its eight-channel configuration can also be divided into two independent 4-channel sections, making it useful when a system must select among several sensor, instrument, or control signals without duplicating downstream amplifiers and converters. The MAX338 is identified as a low-leakage CMOS analog multiplexer. Its 400 ohm on-resistance supports practical routing of medium-impedance analog sources, while a listed leakage figure of 20 pA is useful when measuring high-source-impedance signals. The 16-SOIC package provides a conventional surface-mount footprint suitable for established test-and-measurement boards and industrial control equipment. The MAX338 family is designed around a single multiplexer architecture that can support either an 8:1 arrangement or a dual 4:1 arrangement. The manufacturer describes the MAX338 and MAX339 as pin-compatible upgrades for the DG508A and DG509A, emphasizing their role as established interface-building blocks for instrumentation systems. Their ability to operate from dual supplies also supports bipolar signal ranges where common-mode headroom is required. Typical uses include automated test equipment, data-acquisition systems, industrial process monitoring, laboratory instrument input selection, battery and power-system measurement, and control boards that route several analog channels to a single amplifier or converter. The dual 4-channel capability can shorten signal paths when two groups of four sources must be selected independently. Layout should give priority to keeping mux input and output traces short, maintaining a continuous ground reference, and preventing switched high-impedance nodes from coupling adjacent channels. The power and ground connections must be decoupled close to the device, while unused control and channel inputs should be connected according to the pin-description table in the Analog Devices MAX338 data sheet. This product summary combines the manufacturer family information with distributor and cross-reference records for MAX338MSE/PR3+T. It distinguishes the exact ordering code from related MAX338 package, temperature, and tape-and-reel options and provides application, comparison, and design guidance focused on selecting and implementing this 16-SOIC analog multiplexer.
MAX3483CPA+ - 3.3V 250kbps RS-485 Transceiver | Analog Devices
The Analog Devices MAX3483CPA+ is a 3.3V-powered, half-duplex RS-485/RS-422 transceiver with one driver and one receiver, a 250kbps data rate, and an 8-pin PDIP package. It is designed for low-power serial communications where slew-rate limiting reduces electromagnetic interference and helps control cable reflections. The verified product data identifies the device as a true RS-485/RS-422 transceiver with a 3.3V supply range, commercial through-hole packaging, and receiver hysteresis of 50mV. An RS-485 transceiver is an interface IC that converts digital logic-level signals into differential bus signals and converts received differential signals back into logic-level data. RS-485 is commonly used for longer-distance, noise-tolerant industrial communication, while RS-422 provides a related differential signaling method. The MAX3483CPA+ belongs to the interface IC hierarchy: transceiver, communication interface, interface IC, and semiconductor. Its key verified features include one transmitter and one receiver, 250kbps operation, 3.3V operation, half-duplex communication, 50mV receiver hysteresis, and slew-rate-limited signaling. These characteristics suit equipment interfaces, industrial control links, instrumentation, and embedded systems that require a compact, low-power differential bus interface. The slew-rate-limited driver is particularly useful when longer cables or imperfect terminations create reflection concerns. The MAX3483CPA+ uses a true differential bus architecture rather than a single-ended logic output. Designers must still provide the correct bus topology, cable termination, common-mode handling, grounding, and protection for their installation. The driver and receiver are combined in one package, but the bus interface still requires external application-specific components such as termination resistors, protection devices, and decoupling capacitors. Typical applications include industrial automation, factory equipment, building controls, process monitoring, data acquisition, and embedded communications. A half-duplex arrangement allows the same pair of conductors to transmit and receive, although software or hardware flow control is needed to prevent simultaneous transmission and reception. The verified sources identify the MAX3483 family as low-power 3.3V transceivers, but detailed electrical limits, absolute maximum ratings, and pin-level values are not supplied in the prompt. For a new design, verify the complete manufacturer datasheet for supply tolerance, input and output thresholds, driver current, receiver sensitivity, timing, temperature limits, and ESD information before committing to the PCB. This page distinguishes verified product facts from unavailable parameters and does not infer specifications that were not present in the supplied data.
MAX3483CSA+ - 3.3V 10Mbps RS-485 Transceiver | Maxim

The differential architecture helps reject common-mode noise and supports communication over longer cables or noisier industrial environments. The MAX3483 family combines a transmitter, receiver, and driver-enable control in one package, reducing the number of discrete interface components required in a point-to-point or multidrop RS-485 link. Key verified characteristics include 3.3V operation, operation to 10Mbps according to the manufacturer product-page description, one driver and one receiver per device, and slew-rate-limited operation. The manufacturer product page states that the MAX3483 slew-rate-limited drivers minimize electromagnetic interference and reduce reflections caused by improperly terminated cables. Distributor listings also classify the part as an RS-422/RS-485 interface IC and identify the 8-SOIC package. The device is suitable for industrial equipment, instrumentation, building automation, data acquisition, and embedded control links that require a compact differential interface. A driver-enable input supports direction control in half-duplex RS-485 systems, allowing the transmitter to be disabled when the bus is not being driven. The receiver can then monitor the bus without creating a line conflict. Exact pin names, electrical limits, receiver thresholds, propagation delays, and temperature ratings must be taken from the manufacturer datasheet before final circuit design. For layout, place the transceiver close to the connector and keep differential traces short, matched, and continuous. Provide the supply bypassing and protection required by the selected system-level interface requirements. RS-485 cables normally benefit from termination, biasing, and common-mode protection, but those network components should be designed from the actual cable length, topology, baud rate, and grounding arrangement. This product page consolidates verified manufacturer and distributor information, package classification, source links, and application guidance. It does not invent electrical values absent from the supplied data; consult the MAX3483CSA+ manufacturer datasheet for the complete pinout, timing, electrical characteristics, recommended operating conditions, and application circuit.
MAX3483CSA+T - 3.3V RS-485 Transceiver | Analog Devices
The Analog Devices MAX3483CSA+T is a 3.3 V-powered RS-485/RS-422 transceiver with one driver and one receiver, a maximum data rate of 10 Mbps, and an 8-pin SOIC package. The MAX3483 uses slew-rate-limited signaling to reduce electromagnetic interference and cable reflections, making it suitable for industrial, instrumentation, and communications links. An RS-485/RS-422 transceiver is a physical-layer interface IC that converts logic-level data into differential bus signals and reconstructs logic-level data from differential inputs. The MAX3483 combines a balanced line driver, differential receiver, and 3.3 V power rail in one package. This places it in the interface IC hierarchy alongside bus transceivers, differential line drivers, and differential receivers while providing a compact solution for multidrop industrial buses. The device operates from a single 3.3 V supply and supports 3.0 V to 3.6 V operation. Its slew-rate-limited driver lowers the edge rate of transmitted signals, reducing EMI and reflections that can interfere with slow or poorly terminated cables. The manufacturer identifies the MAX3483 family for data rates up to 250 kbps when its slew-rate-limited operation is used to suppress cable reflections. Analog Devices also describes the MAX3483 as a 10 Mbps RS-485/RS-422 transceiver. The MAX3483CSA+T includes one transmit driver and one receive channel, allowing it to serve as a bus node in point-to-point or multidrop RS-485 networks. Its low-power design is useful in portable test equipment, industrial controllers, and distributed sensors. The separate driver-disable and receiver-enable controls support half-duplex communication and allow the receive path to be disabled when the node is not listening. Typical applications include industrial automation, RS-485 instrumentation, building-control equipment, data acquisition, and communications equipment operating from a 3.3 V rail. The slew-rate-limited driver is particularly appropriate where long cables, imperfect terminations, or adjacent high-speed circuitry could produce reflected or spurious signals. When designing the circuit, route the differential bus as a controlled-impedance pair, provide the termination and biasing required by the selected network topology, and keep the ground return close to the signal path. Confirm that the required baud rate, cable length, topology, and termination strategy are compatible with slew-rate-limited signaling before releasing the PCB layout. This page combines manufacturer specifications, package and lifecycle information, practical RS-485 design guidance, and a focused comparison of documented MAX3483 variants. These engineering details help buyers evaluate the transceiver's voltage, data-rate, package, and ESD-related options before integrating it into a new design.
MAX3483ECPA+ - 12Mbps RS-485 Transceiver | Analog Devices
Analog Devices MAX3483ECPA+ is a 3.3 V-powered, half-duplex RS-485/RS-422 transceiver with one driver and one receiver, a maximum data rate of 12Mbps, and ±15kV ESD protection in an 8-pin PDIP package.

An RS-485 transceiver is an interface IC that converts logic-level signals into differential bus voltages and reconstructs logic-level data from a differential pair. RS-485 belongs to the broader hierarchy of interface ICs, serial-interface transceivers, and communication semiconductors. The MAX3483ECPA+ can operate as both an RS-485 and an RS-422 transceiver, making it suitable for industrial control, instrumentation, and other reliable wired-data links. The principal operating features include a 3.3 V supply, 12Mbps maximum signaling speed, ±15kV ESD protection, and slew-rate-limited RS-485/RS-422 outputs. The transmitter’s controlled edge rate helps reduce electromagnetic interference and ringing on cables. The package includes one driver and one receiver, allowing a half-duplex arrangement in which a transceiver node transmits and receives on the same differential bus. According to the MAX3483E manufacturer documentation, this is a low-power, 3.3 V device intended for industrial communication networks. Its ESD protection helps the interface withstand electrostatic discharge encountered during installation and handling. The receiver operates from the same 3.3 V supply as the transmitter, simplifying power architecture in systems that use modern low-voltage digital logic. The slew-rate-limited driver is particularly useful when long cables, imperfect terminations, or multiple connected nodes create reflection-prone conditions. Typical applications include industrial sensor networks, programmable-logic-controller communication links, instrumentation equipment, data-acquisition systems, and isolated or non-isolated supervisory control links. The MAX3483ECPA+ is also appropriate for embedded systems that require a legacy-compatible 8-pin through-hole footprint and a 3.3 V RS-485 interface. When designing around the MAX3483ECPA+, account for bus-direction control, termination at the physical ends of the differential pair, and common-mode behavior across the installed cable. A transceiver with a 12Mbps capability is not automatically required to operate at that rate; lower signaling rates can improve margin in noisy or poorly terminated installations. This product guide combines the manufacturer’s device description, package and interface characteristics, drop-in replacement assessment, comparison parameters, and practical integration guidance to support faster component selection and PCB-level planning.
MAX3483ECSA+ - 12Mbps RS-485/RS-422 Transceiver | Analog Devices
The Analog Devices MAX3483ECSA+ is a 3.3 V-powered, half-duplex RS-485/RS-422 transceiver with one driver and one receiver, a maximum data rate of 12 Mbps, and enhanced ESD protection of ±15 kV, packaged in an 8-pin SOIC. Its slew-rate-limited transmitter is designed to reduce electromagnetic interference and cable reflections in industrial communications links. An RS-485/RS-422 transceiver is an interface IC that converts between low-voltage digital logic signals and differential bus voltages. It belongs to the transceiver and line-driver hierarchy, which sits under interface ICs and broader semiconductor signal-interface products. Differential signaling provides common-mode rejection, allowing reliable communication over cables exposed to industrial noise, ground-potential differences, and reflected signals. Key features of the MAX3483ECSA+ include operation from a single 3.3 V supply, interoperability with 5 V logic, 12 Mbps maximum data rate, and enhanced electrostatic-discharge protection. The transmitter outputs and receiver inputs are protected to ±15 kV under the Human Body Model, ±8 kV under the IEC 1000-4-2 Contact Discharge method, and ±15 kV under the IEC 1000-4-2 Air Gap Discharge method. The device contains one low-power driver and one receiver in a half-duplex arrangement. A receiver-enable input and driver-enable input control bus direction when the transceiver is used with a shared bus. Slew-rate limiting reduces high-frequency harmonics, lowers EMI, and helps limit reflections caused by imperfectly terminated cables, although cable length, topology, and termination remain important determinants of reliable operation. Typical uses include industrial RS-485 links, RS-422 point-to-point links, building and factory automation, data acquisition systems, and embedded control networks. The half-duplex architecture is particularly appropriate for two-wire multidrop buses, while the same electrical transceiver can support four-wire RS-422 arrangements when direction control is managed appropriately. Designers should place the transceiver close to the connector or board edge, provide a continuous ground reference, route the differential pair as a tightly coupled pair, and install termination at the physical ends of the bus. The supply should be decoupled close to the VCC pin, and unused enable inputs must not float. Cable length and topology should be checked against the data rate because slew-rate limiting alone does not guarantee signal integrity on every installation. This page combines manufacturer and distributor sourcing information with practical interface-design guidance, package-specific comparisons, and application-oriented selection criteria that are not consolidated on a typical distributor listing.
