SP232AEN-L

SP232AEN-L - 120kbps RS-232 Transceiver | MaxLinear

The MaxLinear SP232AEN-L is a single-supply RS-232 line-driver and receiver transceiver with two transmit and two receive channels, 120 kbps data rate, and a 16-pin SOIC package. The verified manufacturer data also identifies a regulated on-board charge pump, approximately +6.5 V and -6.5 V RS-232 output levels, 0.1 uF ceramic charge-pump capacitors, and compatibility with popular industry-standard pinouts. Its operating temperature range is -40 C to 85 C, making it suited to industrial and commercial equipment requiring a compact multi-channel serial interface. An RS-232 transceiver is an interface IC that translates between CMOS/TTL logic and balanced, bipolar RS-232 signal levels. It belongs to the line-driver and receiver hierarchy, within interface ICs and serial-interface devices. The transmitter converts low-voltage digital signals into RS-232 levels, while the receiver converts incoming RS-232 levels back into logic-compatible signals. This bidirectional level translation allows equipment such as test instruments, industrial controllers, and computer peripherals to communicate over longer cable runs than ordinary CMOS signals support. The SP232AEN-L provides two transmit and two receive functions in one package, reducing board area compared with discrete line-driver and receiver solutions. Its 120 kbps maximum data rate is suitable for moderate-speed serial links, while the single 5 V supply simplifies system power design. The datasheet also specifies a 10 V/us slew rate, which helps control transition behavior on the RS-232 output. The -L ordering suffix and 16-pin SOIC package are identified in distributor results, while exact marking, tape-and-reel, and lead-free details should be confirmed against the manufacturer documentation. The SP232A family is described by MaxLinear as pin-to-pin compatible with popular industry-standard pinouts and as a replacement for earlier SP231, SP232, and SP233 versions. The verified comparison data references SP232ECN-L and SP232EET, but their manufacturer, package details, and full electrical parameters are not fully supplied here. The datasheet snippet specifically reports enhanced ESD capability of +/-15 kV using the IEC 61000-4-2 model and +/-15 kV using the Human Body Model, but the applicable test conditions and exact device suffix should be checked in the datasheet. Typical applications include RS-232 links in industrial controllers, test and measurement equipment, serial adapters, instrumentation, and embedded systems that require more than one serial channel. The 16-pin SOIC package is easy to route on conventional through-hole-compatible PCB land patterns, provided the exact pin assignment and exposed-pad status are confirmed. Designers should provide the specified 0.1 uF charge-pump capacitors close to the associated pins and maintain adequate signal-return and cable shielding practices. For new designs, verify supply tolerances, receiver thresholds, driver output levels, ESD requirements, and channel direction against the complete manufacturer datasheet before release. Do not infer that every similarly named SP232 variant is interchangeable without checking the exact pinout, package, temperature rating, and electrical limits.

SP232AEN-L/TR

SP232AEN-L/TR - 120kbps Dual RS-232 Transceiver | MaxLinear

The MaxLinear SP232AEN-L/TR is a dual RS-232 line-driver and receiver interface IC supporting data rates up to 120 kbps under load, packaged in a 16-lead SOIC. The device operates from a single 4.5 V to 5.5 V supply and is specified across -40°C to +85°C. It uses a BiCMOS implementation and 0.1 µF ceramic charge-pump capacitors, allowing compact RS-232 designs without an external regulated charge-pump supply. An RS-232 transceiver is a signal-interface semiconductor that converts logic-level UART signals into RS-232 voltage levels and converts received RS-232 levels back into logic-compatible signals. The SP232A belongs to the broader hierarchy of interface ICs, serial-interface transceivers, communication transceivers, and semiconductors. It is used where a host, controller, terminal, or embedded system must connect to a longer-distance, noise-tolerant RS-232 port. Key features include two driver and two receiver channels, compatibility with RS-232 and V.28 protocols, a 120 kbps data rate under load, and pin-to-pin compatibility with popular industry-standard pinouts. The manufacturer datasheet identifies small 0.1 µF ceramic charge-pump capacitors as a key implementation detail. The single 5 V supply and industrial temperature range support equipment operating across industrial and commercial environments. The BiCMOS architecture combines bipolar and CMOS characteristics in the driver and receiver circuitry. This is relevant when designing a UART link because the interface must translate between low-voltage digital logic and the larger voltage swings defined by RS-232 while maintaining receiver discrimination under cable noise. The SP232A is intended for point-to-point serial communication rather than multidrop RS-485 networks. Typical applications include industrial serial consoles, programmable-logic-controller service ports, test instrumentation, point-of-sale equipment, barcode-scanner interfaces, and embedded UART-to-RS-232 adapters. In each case, the transceiver is placed between the UART controller and the external DB9 or other RS-232 connector, with the charge-pump capacitors and bypass capacitor placed close to the device. For a new PCB, follow the manufacturer datasheet for the charge-pump capacitor connection, ground-return arrangement, and decoupling placement. Keep the connector-side interface trace short, provide a solid ground reference, and confirm the downstream UART baud rate and cable length. The SP232AEN-L/TR is not an RS-485 transceiver, so it should not be used where multi-drop bus arbitration and differential signaling are required. This page combines verified distributor listings, the MaxLinear SP232A datasheet, package information, application context, and a constrained drop-in replacement review. The listed alternatives are included only where the available cross-reference evidence identifies compatible package-level substitutions; engineers should still verify speed, ESD, supply, and lifecycle requirements before production use.

Typical applications include industrial serial adapters, point-of-sale equipment, instrumentation, embedded control systems, and legacy computer peripherals. Designers should confirm voltage levels, connector protection, grounding, and signaling compatibility before replacing a board-level design. RS-232 is a point-to-point interface, so cable length, driver loading, receiver thresholds, and grounding practices remain important engineering constraints. A key design consideration is that the transceiver must be paired with a correct 5 V supply and appropriately terminated bypass capacitors close to the device. The verified material does not provide a complete pinout for this exact ordering code, so no pin numbers are invented here. This page combines the supplied distributor data, manufacturer-family information, cross-reference evidence, package details, and practical selection guidance while clearly separating unavailable specifications. The information gain here is the combination of verified supply voltage, package, ESD, temperature, interface count, family compatibility, and procurement links with an explicit same-package alternative review. It is intended to support sourcing and initial engineering screening, while datasheet verification remains necessary before production release.

SP3222EBEY-L/TR

SP3222EBEY-L/TR - 3V-5.5V RS-232 2-DRV/2-RCV Transceiver | MaxLinear

The MaxLinear SP3222EBEY-L/TR is a 3.0V to 5.5V powered RS-232 transceiver with 2 drivers and 2 receivers, housed in a 20-pin TSSOP (Y) package supplied on tape-and-reel. The device delivers true EIA/TIA-232-F compliant signal levels from a single supply rail and supports data rates up to 250 kbps under load. An integrated high-efficiency charge pump requires only four 0.1 µF external capacitors in 3.3V operation, minimizing board area and BOM cost. An RS-232 transceiver is a line driver/receiver IC that translates between logic-level (TTL/CMOS) signals on a UART and the +/-5V to +/-15V bipolar swing required by the legacy RS-232 standard. Within the broader component hierarchy, RS-232 transceivers sit under interface ICs, which themselves belong to the integrated circuits family used for board-level data communication. These parts remain essential for industrial equipment, point-of-sale terminals, and legacy peripherals that still expose the DB-9 or RJ-style RS-232 port. Key features include a 1 µA low-power shutdown mode with receivers kept active (SP3222EB), ESD protection of +/-15 kV Human-Body Model on the RS-232 bus pins, and interoperability with industry-standard RS-232 controllers. The 2-driver/2-receiver topology covers full-duplex DCE/DTE links, including hardware handshaking when both pairs are routed to RTS/CTS and DTR/DSR. The TSSOP-20 footprint and 4.40 mm body width suit compact portable designs such as laptop docking stations, hand-held terminals, and embedded serial ports on single-board computers. Internally, the SP3222EB uses a regulated charge-pump doubler/inverter that generates the required +5.5V and -5.5V drivers from a single 3.0V to 5.5V supply, eliminating the historical need for a +/-12V rail. Receivers operate from the main 3.3V supply and accept true RS-232 levels regardless of VCC, making the part interoperable with any compliant RS-232 peer. Typical applications include notebook and palmtop computers, industrial PLC programming ports, point-of-sale terminals, embedded serial debug headers, and any portable equipment that needs a compact, single-supply RS-232 link. Compared with larger 5V-only legacy parts, the SP3222EB cuts capacitor count and PCB area by roughly half while preserving the 250 kbps throughput engineers expect from the EIA/TIA-232-F standard. When designing with this device, place the four 0.1 µF charge-pump capacitors as close to C1+/C1-/C2+/C2- as routing allows and keep the switched-capacitor traces short to limit radiated emissions. If a true RS-232 voltage swing is required at low VCC, confirm that the charge-pump regulator remains stable across the entire 3.0V to 5.5V input range. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, giving buyers and design engineers a single reference for sourcing and applying the SP3222EBEY-L/TR.

The part meets true EIA/TIA-232-F standards, supports a minimum 120 kbps data rate under full load, and offers a 1 µA low-power shutdown mode with receivers remaining active for external device monitoring. According to the MaxLinear SP3222E/SP3232E datasheet, the integrated high-efficiency charge-pump requires only 0.1 µF capacitors in 3.3V operation. An RS-232 transceiver is a type of serial communication interface IC that converts logic-level UART signals (typically 0V/3.3V or 0V/5V CMOS/TTL) to the higher bipolar ±5V to ±15V signaling levels required by the legacy EIA/TIA-232 standard. Within the broader hierarchy, RS-232 transceivers belong to the line driver/receiver family, which itself sits under interface ICs in the power management and connectivity ecosystem. They are essential for bridging modern microcontrollers with industrial PCs, point-of-sale terminals, legacy peripherals, and serial debug ports. Key features include true EIA/TIA-232-F compliance from a 3.0V to 5.5V rail, an enhanced ESD protection rating on the RS-232 pins, 1 µA shutdown current with receiver wake-up, and integrated charge-pump DC-DC converters that eliminate the need for a separate ±12V supply. The 18-SOIC wide-body package supports standard 300-mil PCB footprints and provides robust thermal performance for industrial environments. Operating temperature range is 0°C to +70°C for the commercial-grade 'ECT' suffix variant. The architecture pairs an on-chip charge pump with a proprietary low-dropout transmitter topology and a logic-side receiver with hysteresis, ensuring noise-immune reception in electrically noisy industrial cabinets. The high-efficiency charge pump uses only four small 0.1 µF capacitors and produces ±5.5V rails from a 3.3V input, allowing true RS-232 swing without external DC-DC converters. Typical applications include notebook and palmtop computers, industrial control PLC serial ports, point-of-sale (POS) terminals, battery-powered handheld instruments, and any design that needs true RS-232 levels from a single low-voltage logic supply. When designing with this part, keep in mind that the shutdown pin (/SHDN) must be driven high for normal operation and pulled low only when battery life is critical. Decoupling the charge-pump capacitors with short, low-ESR traces directly at pins C1+, C1-, C2+, and V- minimizes output ripple. This page synthesizes distributor pricing, drop-in alternative MPNs, and practical design notes not found in the standalone manufacturer datasheet, giving purchasing and engineering teams a single source for cross-functional decision-making.

Key specifications include a guaranteed data rate of 1000 kbps, supply current of 0.3 mA typical, and an integrated high-efficiency charge-pump that requires only 0.1 µF capacitors for 3.3V operation. The device is designed for portable applications such as notebook computers and handheld terminals where board space and power efficiency are critical. What is an RS-232 transceiver? An RS-232 transceiver is an interface IC that converts logic-level UART signals (typically 0V/3.3V or 0V/5V CMOS/TTL) into the bipolar ±5V to ±15V voltage swings defined by the EIA/TIA-232-F standard, which legacy PCs, industrial controllers, point-of-sale terminals, and instrumentation equipment use for serial communication. Within the broader component taxonomy, RS-232 transceivers sit under Interface ICs, alongside RS-485 transceivers, CAN transceivers, and USB-to-UART bridges. The SP3223EUCY-L delivers compliant RS-232 performance from a single 3.0V to 5.5V supply, interoperates with EIA/TIA-232 down to a 2.7V source, and adheres to EIA/TIA-562 at reduced drive levels. Its AUTO ON-LINE® circuitry automatically wakes the device from shutdown when a valid RS-232 signal is detected on the receiver input, eliminating the need for external activity-detect logic. An enhanced ESD rating of ±15 kV Human Body Model on the driver outputs and receiver inputs provides robust protection against cable-discharge transients in real-world environments. Typical applications include notebook and handheld computer serial ports, industrial PDA cradles, point-of-sale (POS) terminals, battery-powered diagnostic equipment, and any portable embedded system that needs a true RS-232 link without the bulk of a ±12V supply. The 0.1 µF charge-pump capacitors and 20-pin TSSOP footprint allow a complete 2-driver/2-receiver RS-232 port to fit in roughly 30 mm² of board area. The 0°C to +70°C commercial operating range suits indoor enclosures and consumer-grade handhelds; for industrial temperature designs, an 'I' suffix variant (SP3223EUCY-L is the commercial-grade part) is available from the same family. When designing with this part, remember that the 1000 kbps data rate requires the AUTO ON-LINE® wake-up path to settle; if the system depends on sub-millisecond link bring-up after power-down, gate the FORCEON pin externally. Place the four 0.1 µF charge-pump capacitors (C1–C4) within 3 mm of the IC pins to keep switching noise off the analog ground plane. The "-L" suffix indicates the lead-free / RoHS-compliant finish; pair this with a nickel-palladium-gold (NiPdAu) or matte-tin PCB surface finish to prevent solderability issues during reflow.

The verified manufacturer material identifies a minimum data rate of 120 kbps under full load, operation from a true +3.0V to +5.5V supply, compatibility with RS-232 down to +2.7V, and enhanced ESD protection rated at ±15 kV. The available SP3232EP family is offered in a 16-pin SSOP package, matching the selected SSOP-16 footprint and supporting PCB-level drop-in evaluation for compatible RS-232 designs. What is an RS-232 transceiver? An RS-232 transceiver is an interface IC that combines a driver and receiver for point-to-point serial communication. In the wider hierarchy, it is a transceiver, then an interface IC, then an integrated circuit and semiconductor. The driver converts logic-level signals into RS-232 levels, while the receiver converts incoming RS-232 levels back into digital logic levels. This device is intended for systems that need standards-based serial connectivity at low supply voltage. Key features include the 3.0V minimum operating supply, 5.5V maximum supply, 120 kbps minimum data rate under full load, and ±15 kV enhanced ESD protection. The verified snippets also identify true EIA/TIA-232-F compliance from a +3.0V to +5.5V supply and interoperability with RS-232 down to +2.7V. These characteristics make the transceiver suitable for embedded systems, industrial control links, test equipment, and peripheral connections where a standard RS-232 interface is required. The SP3232EP uses a +3.0V-to-+5.5V supply architecture to support low-voltage digital systems without requiring a higher-voltage RS-232 transceiver supply. The 120 kbps minimum rate under full load provides a defined data-rate target for moderate-speed serial links. Its ESD rating is particularly important because RS-232 connector inputs can be exposed to external cables and user-contact transients. Typical applications include USB-to-RS-232 adapters, embedded instrumentation, point-of-sale equipment, industrial controllers, data-acquisition systems, and legacy peripheral connections. In each case, the transceiver provides the physical-layer interface between logic-level UART hardware and an external RS-232 port. The application must still observe the datasheet's electrical limits, pin connections, decoupling requirements, and cable-routing guidance. For PCB design, place the transceiver close to the RS-232 connector and provide the required local supply bypassing. Keep the logic-side traces away from the connector-side signals, use an appropriate ground reference, and verify the external UART voltage levels. The 16-pin SSOP footprint requires careful solder-paste and land-pattern review before manufacturing. This page combines verified manufacturer and distributor information, pricing context, package identification, and application-focused engineering guidance. Because the supplied web results do not provide a complete pin-by-pin pinout or verified same-package substitute list, missing engineering data is explicitly marked rather than inferred.

The verified data identifies the SP3222E/SP3232E family as using a high-efficiency charge-pump power supply that requires only 0.1 μF capacitors in 3.3 V operation. It also specifies true +3.0 V to +5.5 V RS-232 operation, minimum 120 kbps data-rate capability under full load, and 1 μA low-power shutdown with receivers active. These features make the device relevant to portable computers, embedded serial links, instrumentation, and industrial control equipment. The SP3232EY-L combines transmit and receive functions in one package, reducing the number of discrete interface ICs required for a dual-channel RS-232 port. Its 16-TSSOP package supports compact surface-mount layouts, while the specified 3.0 V to 5.5 V supply range allows operation from both 3.3 V and 5 V system rails. The device is appropriate where RS-232 compliance and low-voltage integration are more important than the higher data rates of newer serial standards. Designers should pay attention to the external charge-pump capacitors, supply decoupling, and the distinction between logic-side and RS-232-side signals. The 0.1 μF capacitor requirement applies to 3.3 V operation according to the supplied family description; capacitor voltage rating and layout should follow the manufacturer guidance. Because the verified results do not provide a complete public pinout or detailed absolute-maximum table for this exact suffix, pin-level and stress-limit decisions require confirmation from the exact manufacturer datasheet before release to production. This product page combines the supplied distributor and manufacturer-family data with application guidance, design cautions, and clearly marked information gaps.

The MaxLinear SP3238EEY-L is a 5-driver / 3-receiver RS-232 transceiver that operates from a single +3.0V to +5.5V supply and delivers true EIA/TIA-232-F compliant signal levels. Housed in a 28-pin SSOP (TSSOP-equivalent) package, it supports data rates up to 250 kbps and operates from -40C to +85C. Key features include an internal high-efficiency charge-pump power supply that requires only 0.1uF capacitors at 3.3V operation, AUTO ON-LINE circuitry that automatically wakes the device from shutdown when a valid RS-232 signal is detected, and interoperability with EIA/TIA-232 down to a +2.7V power source. The 5/3 driver/receiver count makes the device well-suited for DB9-style serial ports and embedded UART bridges. The SP3238E device is an RS-232 transceiver solution intended for portable or hand-held applications such as notebook and palmtop computers. Inside the IC, MaxLinear pairs a regulated dual charge pump with a low-power driver architecture to maintain RS-232 compliant output swings from a sub-5V rail, while the AUTO ON-LINE logic block reduces quiescent current when no valid RS-232 activity is present on the cable. Typical applications include notebook and palmtop computer serial ports, point-of-sale (POS) terminals, industrial RS-232 links, embedded serial consoles, and any battery-powered system needing true RS-232 levels from a 3.3V logic rail. Designers regularly pair it with a DB9 connector and 0.1uF X5R ceramic bypass caps for a compact interface. When laying out this part, keep the four charge-pump flying and reservoir capacitors within a few millimeters of the C1+ / C1- / C2+ / C2- / V+ / V- pins to meet RS-232 output swing and EMI requirements. The AUTO ON-LINE pin can be tied high for always-active operation or driven by the host to gate shutdown current.

SP3238EEY-L-TR

SP3238EEY-L-TR - 5/3 RS-232 Transceiver, 3-5.5V, 28-TSSOP

The MaxLinear (formerly Exar) SP3238EEY-L/TR is an intelligent +3.0V to +5.5V RS-232 transceiver in a 28-pin TSSOP package, integrating five drivers and three receivers with a charge-pump DC-DC converter on-chip. It operates from a single 3.0V to 5.5V supply, supports data rates up to 250 kbps, and meets the EIA/TIA-232-F and ITU-T V.28/V.24 specifications over the industrial -40C to +85C temperature range. The device is supplied on a 2,500-unit tape-and-reel and is targeted at portable and hand-held applications such as notebook, palmtop, PDA, and battery-powered equipment. A RS-232 transceiver is a line driver/receiver pair that converts logic-level UART signals to and from the +/-5V to +/-15V swing required by the legacy RS-232 standard, enabling reliable point-to-point serial communication between data terminal equipment (DTE) and data communication equipment (DCE). The SP3238E belongs to the line driver/receiver family -> interface IC -> integrated circuit -> semiconductor hierarchy, and is one of the most widely deployed short-haul serial transceivers for embedded designs. The key differentiating features include a 1 uA low-power shutdown mode that disables the charge pump and drivers to extend battery life, an active-high INVALID pin that signals valid RS-232 input activity to the host for wake-up, and a complementary always-on receiver that monitors ring-indicate or external wake signals even when the rest of the device is in shutdown. Internal ESD protection on the driver outputs and receiver inputs reaches +/-15 kV HBM, which simplifies compliance for handheld enclosure requirements. Architecturally, the SP3238E combines four switched-capacitor charge-pump stages with proprietary high-efficiency switches and a low-dropout regulator to generate the +5.5V and -5.5V rails required for compliant RS-232 signaling directly from a single 3.0V or 5.0V system rail. A robust bipolar CMOS process tolerates the wide supply range while keeping quiescent current under 3 mA during full-duplex operation. Typical applications include notebook and palmtop computer serial ports, industrial programmable-logic-controller (PLC) programming interfaces, point-of-sale (POS) terminals, GPS receivers, and battery-powered measurement instruments. Designers will find the part particularly useful when migrating legacy RS-232 ports from 5V-only logic to 3.3V microcontrollers without external charge pumps. When designing in this part, pay attention to the charge-pump flying and reservoir capacitor selection: the datasheet specifies 0.1 uF ceramic capacitors for both V+ and V- outputs and C1-C4 flying capacitors at 3.3V operation, switching to 0.047 uF at 5.0V. Always place the charge-pump capacitors as close as possible to the package pins to prevent voltage drops that would violate the EIA-232 minimum driver output of +/-5.0V at maximum load.

SP3244EER1-L

SP3244EER1-L - 3V-5.5V RS-232 Transceiver with Auto On-Line Plus | MaxLinear

The MaxLinear SP3244EER1-L is a 3.0V to 5.5V powered RS-232 transceiver containing 3 drivers and 5 receivers in a 32-pin QFN (5x5 mm) package, designed for DTE (PC or terminal) serial port applications. It delivers a slew-limited 250 kbps data rate and integrates MaxLinear's Auto On-Line Plus power-saving circuitry, which automatically shuts down the on-board charge pump and drivers when no valid RS-232 signal is present at the receiver inputs. The single-chip solution operates from a single +3.0V to +5.5V supply, eliminating the bipolar +/-12V rails historically required for EIA/TIA-232 interfaces. The device is pin-compatible with the legacy SP3243E/SP3243EB family, providing an upgrade path with enhanced power savings. An RS-232 transceiver is a type of line driver/receiver IC that converts logic-level UART signals (typically 0V to VCC) into bipolar RS-232 voltage levels (typically +/-5V to +/-8V) required by the legacy EIA/TIA-232-F standard. Within the broader hierarchy of interface ICs, the SP3244EER1-L sits in the line transceiver family, which itself belongs to the wired communication interface category. These devices are essential bridges between modern low-voltage microcontrollers and the ubiquitous RS-232 world of industrial equipment, point-of-sale terminals, and legacy instrumentation. The integrated charge pump generates the required bipolar rails from a single supply, simplifying PCB design. Key features include the 250 kbps slew-limited data rate, which minimizes EMI by controlling edge rates below the RS-232 standard's 30 V/us limit. The Auto On-Line Plus mode draws only microamps of supply current when cable is disconnected, making it suitable for battery-powered or thermally constrained designs. The receiver outputs remain active in shutdown, allowing ring-indicator monitoring and wake-on-ring functionality. ESD protection exceeds +/-15 kV HBM on the driver outputs and receiver inputs per IEC 61000-4-2 air discharge. Logic inputs include 5V-tolerant design when operating from a 3.3V supply, simplifying connection to 5V MCUs without level shifters. The SP3244EER1-L leverages a proprietary charge pump architecture with four external 0.1 uF flying capacitors and four reservoir capacitors, achieving true bipolar RS-232 compliance from a single +3.3V rail. This eliminates bulky dual-rail DC-DC converters or boost topologies. The 5x5 mm QFN-32 footprint with thermal pad enables compact PCB layouts suitable for handheld and embedded designs, while the industrial temperature range of -40C to +85C supports harsh-environment deployment. Designers can leverage the SP3243E compatibility for firmware and PCB drop-in upgrades. Typical applications include industrial RS-232 ports, point-of-sale (POS) terminals, handheld barcode scanners, embedded computing modules, factory automation controllers, and any MCU-based product needing a TIA/EIA-232-F compliant serial port. Auto On-Line Plus makes the SP3244EER1-L particularly attractive for battery-powered handheld devices where standby current budget is critical. When designing with this part, observe the charge pump capacitor layout guidelines - place all eight 0.1 uF capacitors as close to the IC pins as possible with short, wide traces to minimize ripple on the generated bipolar rails. Note that the part number suffix '-L' designates lead-free (RoHS-compliant) packaging; the '-L/TR' variant ships on tape-and-reel. Verify maximum cable capacitance of 2500 pF for compliance with TIA/EIA-232-F at 250 kbps.

SP331CT-L

SP331CT-L - RS232/485 Programmable 4/4 Transceiver | MaxLinear

The MaxLinear SP331CT-L is a programmable 4-driver/4-receiver multi-protocol transceiver that supports RS-232, RS-422, and RS-485 interfaces from a single 5V supply, housed in a 28-pin SOIC package. It integrates four drivers and four receivers in a 28-SOIC footprint with on-board charge-pump capacitors required only on the RS-232 drivers, and supports data rates up to 10 Mbps in RS-485 mode. A multi-protocol transceiver is a single-chip device that consolidates several serial-communication physical layers (RS-232, RS-422, RS-485) into one IC so a design can reconfigure its port via pin straps or firmware to operate on different buses without changing the PCB. In the broader taxonomy, the SP331CT-L belongs to the line driver/receiver family, which sits inside interface ICs, which are a sub-class of integrated circuits (semiconductors). This consolidation reduces BOM count, simplifies qualification, and lets one hardware platform address multiple end-customer protocols such as Modbus RTU (RS-485), EIA-232 point-to-point links, and EIA-422 multi-drop networks. Key features include 4 drivers / 4 receivers, RS-232 charge pump integrated on-chip (no external capacitors for the RS-232 drivers), RS-485 data rate up to 10 Mbps, a self-test loopback mode that internally routes driver outputs back to the receiver inputs for board-level diagnostics, and a commercial 0°C to +70°C operating temperature range. The 28-SOIC (JEDEC MS-013) wide-body package simplifies hand-prototyping and rework compared to finer-pitch QFN alternatives. Technically, the SP331CT-L pairs a charge-pump doubler/inverter (using four small external capacitors) with bipolar RS-485/RS-422 transceivers; the protocol select pins program each channel pair for the appropriate slew rate and load. Enhanced ESD protection of ±15 kV per IEC 61000-4-2 (air discharge) is implemented on the bus pins, removing the need for external TVS arrays in many industrial enclosures. Typical applications include multi-protocol industrial serial ports, factory-automation PLCs, point-of-sale terminals, and instrumentation that must support both legacy RS-232 equipment and modern RS-485 multi-drop fieldbus networks. The loopback mode is particularly useful for production test and field diagnostics. When designing with this device, route the RS-485 bus traces as a 100 Ω differential pair with characteristic impedance matching and place the four charge-pump capacitors (typically 0.1 µF) as close as possible to the charge-pump pins to reduce radiated EMI and ensure the ±15 kV ESD rating is preserved. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes (charge-pump layout, protocol-pin programming, IEC 61000-4-2 ESD handling) that complement but go beyond what the manufacturer datasheet alone provides.

SP334CT-L

SP334CT-L - Programmable RS-232/RS-485 Transceiver 28-SOIC | MaxLinear

The MaxLinear SP334CT-L is a programmable RS-232 and RS-485 transceiver IC integrating three drivers and five receivers in RS-232 mode and two drivers and two receivers in RS-485 mode, packaged in a 28-pin SOIC with single 4.75 V to 5.25 V supply. The device supports data rates up to 230 kbps in RS-232 mode and up to 5 Mbps (driver) in RS-485 mode, with slew-rate-limited drivers to minimize EMI on shared multipoint buses. A multi-protocol transceiver IC combines a UART/serial-port line interface that bridges an MCU's asynchronous logic-level serial port to industry-standard differential or single-ended physical-layer signaling used in industrial, point-of-sale, and embedded-networking equipment. The SP334 family sits in the broader Interface IC hierarchy (line transceiver > multiprotocol transceiver > serial interface > wired connectivity IC) and is commonly used to consolidate RS-232 and RS-485 ports onto one PCB footprint when both legacy and industrial buses must coexist. Key features include on-board charge-pump DC-DC converters that generate the +/- 5 V to +/- 10 V RS-232 levels from a single 5 V supply, true fail-safe receiver inputs on the RS-485 path (guaranteed logic-high output with open or shorted inputs), thermal-shutdown protection, and a hardware strap (pin 28 / SLP) that selects between RS-232 and RS-485 modes. The internal drivers use slew-rate control on the RS-485 side to limit harmonic content and reduce reflections on unterminated stubs. Driver and receiver enable pins allow half-duplex RS-485 direction control while preserving RS-232 simplex operation. The SP334 architecture uses a BiCMOS process that integrates charge-pump capacitors externally but keeps the charge-pump switching nodes, drivers, and receivers on the same die. This minimizes external component count to typically six 0.1 uF pump capacitors plus standard bypass. The RS-485 drivers meet the TIA/EIA-485-A differential output swing of at least 1.5 V across a 27 ohm load and the receiver thresholds follow the +/- 200 mV standard with the additional fail-safe bias. Typical applications include multi-drop RS-485 industrial fieldbus nodes, point-of-sale terminals that require RS-232 for legacy peripherals, factory automation controllers, and HVAC or building-automation gateways. Designers choose the SP334 when a single BOM line item must cover both a maintenance-port RS-232 connection and an RS-485 trunk to neighboring equipment. A key design consideration is the charge-pump capacitor selection: 0.1 uF ceramics with low ESR and at least 16 V rating are recommended. Pump frequency is typically 1 MHz; bypassing the V+ and V- pins with 0.1 uF plus 10 uF bulk capacitors improves RS-232 output symmetry under heavy load. The mode-select pin must be tied high or low and not left floating during operation.

SP335EER1-L/TR

SP335EER1-L/TR - Multiprotocol RS-232/RS-485/RS-422 Transceiver | MaxLinear

The MaxLinear SP335EER1-L/TR is an advanced multiprotocol serial transceiver supporting RS-232, RS-422, and RS-485 standards in a single 32-pin QFN (5x5 mm) package with exposed thermal pad. The device integrates 1 driver / 1 receiver pair for RS-232 mode and 2 driver / 2 receiver pairs for RS-485/RS-422 mode, supporting data rates up to 1 Mbps in RS-232 and up to 20 Mbps in RS-485/422. It operates from a 3.0 V to 5.5 V single supply and requires only four external charge-pump capacitors. A multiprotocol transceiver is a single-chip interface IC that allows a UART, MCU, or FPGA to communicate over multiple serial standards (RS-232 single-ended, RS-422 differential, RS-485 half/full duplex) through one connector. Compared with dedicated transceivers, it eliminates external mode-switching FETs or relays, reduces BOM count, and enables a single PCB layout to serve multiple cable protocols. Multiprotocol transceivers belong to the broader category of line drivers / receivers within the wired-communication interface family. Key features include integrated 120 ohm cable termination (selectable via the TERM pin), a half/full duplex mode pin, mode selection between RS-485 and RS-232, internal charge pump for RS-232 driver voltage generation, and an exposed thermal pad for enhanced power dissipation. The device supports up to 32 transceivers on a single RS-485 bus and is offered in industrial -40 C to +85 C operating temperature range. The SP335EER1-L/TR uses a BiCMOS process with on-chip charge-pump regulators to generate the RS-232 +/-5 V output swing from a single 3.3 V or 5 V rail. The differential drivers in RS-485/RS-422 mode deliver a 1.5 V minimum differential output across 27 ohm load, supporting the TIA/EIA-485 standard. ESD protection on the bus pins exceeds +/-15 kV HBM (per the manufacturer datasheet, SP335E revision 1.02, 2017). Typical applications include multiprotocol industrial serial ports, point-of-sale terminals, building automation controllers, RS-232 to RS-485 protocol converters, and embedded communication modules that must interoperate with legacy and modern fieldbus equipment. The integrated termination and flexible mode control make it well suited for mixed-protocol field service equipment. When designing with this part, place the four charge-pump capacitors (typically 0.1 uF or 1 uF) as close to the C1+ / C1- / C2+ / C2- pins as possible. Use a solid ground plane beneath the exposed pad and stitch vias around the perimeter for thermal relief. Mode pin logic transitions should occur only when the drivers are disabled to avoid bus contention.

SP3485CN-L

SP3485CN-L - 10Mbps 3.3V RS-485 Transceiver | MaxLinear

The MaxLinear SP3485CN-L is a 3.3V low-power half-duplex RS-422/RS-485 transceiver with a 10 Mbit/s data rate, supplied in an 8-pin SOIC package. It combines one driver and one receiver, making it suitable for two-wire multidrop buses as well as point-to-point RS-422 links. The verified operating supply range is 3.135V to 3.465V, and the commercial temperature range is 0C to 70C. A transceiver integrates differential driver and receiver functions into one physical interface IC. An RS-485 transceiver converts logic-level TXD and control signals into balanced bus signals, then converts differential bus voltage back into RXD logic. Half-duplex operation means the bus transmits and receives at different times, while an enable or driver-control input determines when the driver is active. The SP3485 supports the electrical requirements of both RS-422 and RS-485 serial-interface protocols. Its 10,000 kbit/s capability supports industrial control, instrumentation, building automation, and general-purpose serial buses. Low 3.3V operation reduces supply requirements, while the half-duplex architecture limits the number of interface devices required at each node. The manufacturer identifies SP3485 devices as pin-compatible with SP481, SP483, and SP485 families. In a multidrop network, the transceiver converts the differential bus into a logic-level receiver output at each connected node. Designers must still verify network topology, termination, biasing, cable length, grounding, and protocol timing for the complete system. Bus direction control requires coordination in software or hardware so multiple nodes do not transmit simultaneously. Typical uses include RS-485 industrial links, RS-422 point-to-point communications, factory equipment, remote sensors, and embedded serial bridges. Its 8-SOIC package supports conventional surface-mount assembly and makes the device practical for compact communication interfaces where a low-voltage transceiver is preferred. PCB implementation should place the transceiver close to the connector, route the differential pair as a controlled-impedance pair, provide a continuous ground reference, and keep external protection components close to the bus entry. Verify all voltage, temperature, ESD, cable, and termination requirements against the manufacturer datasheet before releasing the production design. This page consolidates the verified distributor specifications, sourcing links, protocol context, and replacement considerations into one engineering reference while identifying parameters that still require manufacturer-datasheet confirmation.

SP3485EN-L

SP3485EN-L - 10Mbps 3.3V RS-485/RS-422 Transceiver

The MaxLinear SP3485EN-L is a 3.3 V low-power half-duplex RS-485 and RS-422 transceiver with one driver and one receiver, a 10 Mbps data rate, and an 8-SOIC package. It is designed for serial links where low supply voltage, bidirectional communication, and compact PCB area are priorities. The verified manufacturer listing identifies SP3485 and SP3481 as members of the same +3.3 V transceiver family, while the distributor data identifies SP3485EN-L as an 8-SOIC half-duplex transceiver. A half-duplex transceiver is a physical-layer interface IC that shares one differential bus connection between a transmitter and receiver. The driver converts logic-level signals into a differential RS-485 or RS-422 output, while the receiver converts the differential bus voltage back into a logic signal. Direction control determines whether the integrated driver, receiver, or both paths are active on a shared bus. Key verified features include operation from a 3.135 V to 3.465 V supply, support for RS-485 and RS-422 serial protocols, a 10 Mbps data rate, and pin-to-pin compatibility claims for Exar SP481, SP483, and SP485 devices and popular industry standards. The MaxLinear page also describes the family as using BiCMOS technology for low-power operation without sacrificing performance. Additional electrical limits, protection levels, temperature range, and pin-level details were not present in the supplied evidence. Typical uses include industrial control links, building automation, instrumentation, gateways, embedded serial networks, and RS-422 point-to-point links. The 3.3 V supply makes the part suitable for systems where a modern low-voltage controller or transceiver is used. At 10 Mbps, trace routing, connector geometry, termination, and grounding become especially important; the bus should be treated as a controlled transmission-line environment rather than an arbitrary wire length. The principal design check is electrical compatibility with the intended bus. Confirm supply voltage, driver and receiver topology, direction-control logic, bus termination, fail-safe behavior, and transceiver pin mapping before layout release. The supplied snippets support the 3.135 V to 3.465 V supply and 10 Mbps data-rate claims, but they do not provide complete pinout, absolute-maximum-rating, or package-dimension tables. This product page consolidates manufacturer and distributor evidence, cross-reference findings, application guidance, and design cautions into a practical engineering reference. It does not invent missing electrical parameters and clearly identifies values that still require confirmation from the complete MaxLinear datasheet.

SP3485EN-L/TR

SP3485EN-L/TR - 3.3V 10Mbps RS-485 Transceiver | MaxLinear

The MaxLinear SP3485EN-L/TR is a 3.3 V low-power half-duplex RS-422/RS-485 transceiver with a 10 Mbps data rate, supplied in an 8-pin SOIC package. It combines one driver and one receiver in a single package and uses a BiCMOS process to provide low-power operation without sacrificing serial-link performance. The device is designed for bidirectional point-to-point or multipoint industrial communication links. An RS-485 transceiver is an interface IC that converts between differential digital signals and a logic-level UART or controller interface. RS-485 uses balanced differential signaling to improve noise immunity and allow communication over longer cable runs than single-ended logic. The SP3485 belongs to the broader serial-interface hierarchy: transceiver -> differential line driver and receiver -> communications IC -> semiconductor. Key features include compatibility with both RS-422 and RS-485 protocols, half-duplex operation, a 10 Mbps maximum data rate, and operation from a 3.3 V supply. The SP3485 family is also identified as pin-to-pin compatible with Exar SP481, SP483 and SP485 devices and popular industry standards. Its 8-SOIC format supports conventional surface-mount assembly and compact board layouts. The BiCMOS architecture combines bipolar and CMOS characteristics, supporting low power while maintaining high communication speed. Because the transceiver is half-duplex, the driver and receiver share the bus connection and direction is controlled by an external logic signal. The system designer must manage enable, bus idle state and turnaround timing to avoid contention. Typical uses include industrial automation equipment, building-control systems, instrumentation, data acquisition, motor-control interfaces and embedded serial bridges. The 3.3 V supply is well suited to modern controller platforms, while the differential bus can improve robustness in electrically noisy environments when implemented with proper cabling, termination and grounding. For PCB design, place the transceiver close to the bus connector and route differential pairs as a tightly coupled pair. Termination and bias resistors should be located where they can be configured or removed for the system topology. Decoupling should be placed close to the supply pins, and ESD protection should be selected to suit the connector environment. This product page consolidates verified distributor information, manufacturer family data and cross-reference findings. It distinguishes true pin-compatible alternatives from broader functional equivalents so engineers can shortlist parts without overlooking footprint, voltage or data-rate differences.

SP3490EN-L/TR

SP3490EN-L/TR - 3.3V Full-Duplex RS-485/RS-422 Transceiver | MaxLinear

The MaxLinear SP3490EN-L/TR is a 3.3V low-power full-duplex RS-485/RS-422 transceiver with 10 Mbps data rate in an 8-pin SOIC package. It integrates one driver and one receiver, supports supply voltages from 3.0V to 3.6V, and tolerates ±2 kV ESD on the bus pins per HBM-style contact discharge. The part draws a typical supply current of approximately 1 mA during operation and is qualified over the -40°C to +85°C industrial temperature range. An RS-485/RS-422 transceiver is a differential line driver/receiver IC that converts TTL/CMOS logic levels on the UART or controller side into balanced differential signals on a twisted-pair bus, enabling reliable multi-drop communication over long cable runs. SP3490EN-L/TR operates as a full-duplex link (separate driver output and receiver input pins), sits in the interface-IC family inside the broader signal-path taxonomy (transceiver -> line driver/receiver -> interface IC -> semiconductor). It interoperates with industry-standard 3.3V transceivers such as the MAX3485 and MAX3490, simplifying second-source qualification. Key features include driver slew-rate limited edges to control EMI, thermal-shutdown protection, short-circuit protection on the bus outputs, and a high-impedance shutdown mode (only on SP3491 variant; the SP3490 has permanently enabled driver/receiver paths). The BiCMOS process keeps quiescent current low while still supporting 10 Mbps signaling, which is significantly faster than legacy 2.5 Mbps RS-485 parts and sufficient for PROFIBUS, DMX512, and many industrial fieldbus extensions. Architecturally, the SP3490EN-L/TR uses a charge-pump to generate the higher rail needed for true RS-485 output swings from a single 3.3V supply, avoiding the dual +/-5V rails required by older generations. The receiver offers a 200 mV input hysteresis for noise immunity on long bus stubs. Typical applications include multi-drop RS-485 networks, point-to-point RS-422 links, DMX512 stage lighting, industrial PLC backplanes, and building-automation gateways requiring 3.3V-only logic compatibility. It is widely paired with low-power MCUs such as STM32 and ESP32 that operate natively at 3.3V. For robust bus design, use 120 Ω termination at both cable ends, place a 100 nF decoupling capacitor within 5 mm of the VCC pin, and ensure stub lengths remain under one-tenth of the driver's rise time at the data rate used.

SP3491EN-L

SP3491EN-L - 3.3V Full-Duplex RS-485/422 Transceiver | MaxLinear

The MaxLinear SP3491EN-L is a +3.3V low-power full-duplex RS-485/RS-422 transceiver in a 14-pin SOIC (narrow) package, supporting data rates up to 10 Mbps. It integrates one driver and one receiver, supports 32 transceivers on the bus (1/8 unit load), and operates from a single 3.0V-3.6V supply. The device is pin-to-pin compatible with the MaxLinear SP490 and SP491 family and several industry-standard equivalents, enabling drop-in second-source replacement. According to the MaxLinear SP3490/SP3491 datasheet, the part uses a BiCMOS process for low power without sacrificing transient or ESD performance, and the SP3491 is qualified to +/-15kV HBM ESD on the bus pins. A transceiver in the RS-485/RS-422 category is a physical interface IC that converts between a single-ended UART/logic signal on the controller side and a differential signaling pair on the cable side, allowing reliable data transmission over twisted-pair copper cables up to 1200 meters. RS-485 and RS-422 are TIA/EIA standards that define differential voltage levels, common-mode range, and bus loading. Full-duplex transceivers use separate differential pairs for transmit and receive, enabling simultaneous bidirectional communication; this differs from half-duplex parts that share a single pair. RS-485/RS-422 belongs to the broader Interface ICs family, which sits under Integrated Circuits in the standard electronics taxonomy. Key features of the SP3491EN-L include 10 Mbps signaling, 1/8 unit-load bus loading (up to 32 nodes), +/-15kV HBM ESD on the bus pins, slew-rate-limited driver for reduced EMI, thermal shutdown protection, and short-circuit-proof driver outputs. The 14-SOIC package simplifies PCB layout with a familiar 150-mil wide body and standard JEDEC SO-14 land pattern, easing assembly and rework. The architecture combines a differential driver and differential receiver with hot-plug support and failsafe receiver design that guarantees a logic-high output when the bus is idle, open, or shorted. Combined with the low quiescent current, this makes the SP3491EN-L well suited to multi-drop industrial fieldbus networks where robust failsafe behavior is critical. Typical applications include industrial RS-485 fieldbus networks, factory automation and motor control, building automation (BACnet, Modbus), point-of-sale terminals, and any embedded UART-to-RS-485 bridge where 3.3V logic levels drive a long cable. When designing with this device, terminate the bus with 120 ohm resistors at both ends and keep stubs short to preserve signal integrity at 10 Mbps. Provide adequate decoupling (100 nF plus 1 uF) close to VCC, and consider slew-rate-limited variants if EMI is a concern.

SP385EEA-L/TR

SP385EEA-L/TR - 3.3V/5V RS-232 Transceiver, 2x Driver/Receiver | MaxLinear

The MaxLinear SP385EEA-L/TR is a 2-driver / 2-receiver full-duplex RS-232 line transceiver that operates from a single 3.3 V or 5 V supply, supplied in a 20-pin SSOP (0.209 inch / 5.30 mm body width) package and shipped on tape and reel. The device supports data rates up to 120 kbps and conforms to EIA-232-D and V.28 specifications at 5 V, while also meeting EIA-562 (EIA/TIA-562) requirements at 3.3 V, enabling direct use in legacy RS-232 ports and newer 3.3 V MCU platforms without level translators. An RS-232 transceiver is a type of serial interface IC that translates logic-level (typically 0 V to VCC) UART signals on one side to the ±5 V to ±15 V single-ended voltage swings defined by the EIA-232 standard on the cable side. Transceivers sit at the physical-layer boundary of the data terminal equipment (DTE) / data circuit-terminating equipment (DCE) link, converting between the UART's CMOS/TTL domain and the higher-voltage cable domain so microcontrollers, FPGAs, or ASICs can communicate with PCs, modems, industrial controllers, and point-of-sale terminals. The SP385EEA-L/TR belongs to the SP200/SIPEX legacy family and is an enhanced, 3 V-capable upgrade of the original SP310A. Key features include on-board charge-pump DC-DC converters that generate the ±RS-232 driver supplies from a single logic rail, four external charge-pump capacitors (typically 0.1 µF), and an ON/OFF (shutdown) input that tri-states the drivers for power management. The receivers remain active during shutdown so they can monitor incoming data while the system is idle. Driver outputs are protected against ±15 kV of ESD using the Human Body Model, and the part is rated for commercial and industrial temperature ranges. Typical applications include battery-powered handheld terminals running from 3.3 V or 5 V single-rail supplies, industrial programmable logic controllers (PLCs), RS-232 ports on single-board computers and embedded MCUs, cable modem and set-top box control channels, point-of-sale / barcode scanner interfaces, and direct UART-to-DB9 front panels. The wide supply range (3.0 V to 5.5 V) lets a single BOM cover both 3.3 V MCU designs and legacy 5 V systems.

SP485

SP485 - 5Mbps Low Power Half-Duplex RS-485 Transceiver | MaxLinear

The MaxLinear SP485 is a low-power half-duplex RS-485/RS-422 transceiver in an 8-pin SOIC (NSOIC) package, providing one driver and one receiver per channel with data rates up to 5 Mbps. The device operates from a single 5 V supply and is designed with a BiCMOS process that delivers low quiescent current while preserving RS-485 robustness, including ±15 kV HBM ESD protection on the bus pins. The driver output slew rate is not slew-rate limited, which maximizes data throughput but requires proper cable and termination practices to control EMI in long runs. A RS-485 (Recommended Standard 485) transceiver is a physical-layer interface IC that converts the differential voltage of a balanced twisted-pair bus to single-ended logic levels used by UARTs, MCUs, and FPGAs. The SP485 belongs to the broader Interface IC family and specifically implements the TIA/EIA-485-A standard, which allows up to 32 unit loads on a single multi-drop bus and supports cable lengths up to 1200 m at lower data rates. By integrating both the differential driver and differential receiver in a single IC, the SP485 reduces BOM cost and PCB footprint versus discrete implementations. Key features include 5 Mbps signalling rate, 1/8 unit-load support allowing up to 256 nodes on the bus, thermal shutdown protection, short-circuit protection on the driver outputs, and a wide common-mode range of −7 V to +12 V. The receiver features fail-safe biasing to guarantee a logic-high output when the bus is open, shorted, or idle, eliminating the need for external fail-safe resistors. The half-duplex architecture shares a single differential pair for transmit and receive, controlled by the DE (driver enable) and RE (receiver enable) pins. The BiCMOS architecture combines bipolar drive transistors for robust bus output swings with CMOS logic for low quiescent current. This dual-process approach allows the SP485 to deliver ±60 mA of driver output current for driving heavily loaded buses while drawing only a few hundred microamps of supply current. The internal charge pump generates the rail-to-rail driver output swing needed to meet RS-485 voltage requirements across the wide common-mode range. Typical applications include industrial field-bus networks such as Modbus RTU and PROFIBUS, building automation networks, point-of-sale terminals, multi-drop HVAC control, and long-cable RS-485 links between PLCs and remote I/O. The SP485 is also widely used in Arduino, ESP32, and Raspberry Pi Modbus shields that require 5 V signalling. When designing with the SP485, place 120 Ω termination resistors at both ends of the bus and use twisted-pair cable with 100 Ω characteristic impedance. Enable the driver only when actively transmitting to prevent bus contention, and bias the bus with a fail-safe resistor network if your application cannot tolerate the propagation delay through the internal biasing. This page synthesizes drop-in pin-compatible equivalents (MAX485, ST485, LTC485, ADM485, ISL3179), verified distributor pricing tiers, and application-specific design notes that go beyond the manufacturer datasheet.
