SP232ACT-L - 120kbps RS-232 Transceiver | MaxLinear
The MaxLinear SP232ACT-L is a 120 kbps RS-232 line transceiver with two drivers and two receivers, a single +5 V supply, and a 16-pin SOIC package. Its BiCMOS implementation supports low-power operation, ceramic charge-pump capacitors, and compatibility with established RS-232 interface layouts. An RS-232 transceiver is an interface IC that converts between digital logic levels and the bipolar voltage levels used by RS-232 serial links. Within the hierarchy of interface semiconductors, it sits between general-purpose logic ICs and communications transceivers. The SP232ACT-L integrates charge-pump circuitry, transmit drivers, and receive comparators to support point-to-point serial communication over cables or board-level links. Key features include operation from a 4.5 V to 5.5 V supply, a guaranteed transmission rate of 120 kbps, and compatibility with RS-232F and ITU V.28 requirements. The device operates with 0.1 F ceramic capacitors, supports a 10 V/µs slew rate, and provides enhanced ESD protection up to ±15 kV under the cited IEC 61000-4-2 and HBM test conditions. The BiCMOS architecture combines low-power CMOS circuitry with bipolar output stages capable of driving RS-232 loads. Its pin-compatible relationship with established industry-standard layouts simplifies replacement and PCB migration. Because the interface uses charge-pump-generated bipolar voltages for transmission, board design must account for capacitor placement, return-current flow, and ESD protection around the external connector. Typical applications include industrial serial consoles, data acquisition systems, test and measurement equipment, embedded control interfaces, and legacy RS-232 peripheral connections. The 120 kbps rate is suitable for command and control traffic rather than high-bandwidth data transfer. For reliable implementation, place the charge-pump capacitors close to their associated pins and provide a clean return path between the interface ground and the external connector. Confirm line voltage, cable length, and grounding before assuming the full 120 kbps specification applies to every cable and load arrangement. This product page combines verified manufacturer and distributor information, drop-in cross-reference data, comparison parameters, and application guidance to support faster component selection, sourcing, and circuit implementation.
SP232ACT-L/TR - 120kbps RS-232 Transceiver | MaxLinear
The MaxLinear SP232ACT-L/TR is a single-supply RS-232 line-driver and receiver IC with two drivers and two receivers, a maximum data rate of 120 kbps, and a 16-SOIC package. It operates from a single +5 V supply and supports 0–70 °C commercial-temperature applications. The device also provides a 10 V/µs slew rate and an on-board regulated charge pump that produces approximately ±6.5 V for compliant RS-232 signal levels. An RS-232 transceiver is an interface IC that bridges TTL-compatible digital logic and balanced, single-ended RS-232 communications. The SP232A belongs to the RS-232 transceiver hierarchy: interface IC, communications transceiver, line driver and receiver, and power-management-assisted interface. Its integrated charge-pump circuit raises the +5 V supply to the positive and negative voltages required for RS-232 drivers, while the receiver section converts incoming RS-232 levels back into TTL-compatible signals. Key features include two transmit channels, two receive channels, 120 kbps operation under load, 10 V/µs driver slew rate, and operation with small 0.1 µF ceramic charge-pump capacitors. The SP232A is designed to be pin-to-pin compatible with popular industry-standard RS-232 pinouts, simplifying replacement of compatible transceivers. Its 16-SOIC format also supports compact point-to-point and multi-port serial-interface designs. Technically, the charge pump generates the bipolar voltage required by the drivers, and the transmitter circuitry converts TTL input levels into RS-232 output levels. The receiver threshold circuitry detects the negative-going RS-232 signal used to indicate logic one. Because this is a single-supply design, system designers should account for the remaining voltage-drop budget across the interface and cable rather than assuming a modern low-voltage RS-232 architecture. Typical uses include industrial serial consoles, instrumentation, data acquisition, point-of-sale equipment, security systems, and embedded control boards. The device is especially useful where a legacy RS-232 port must coexist with +5 V TTL logic and where a 120 kbps data rate is sufficient. For new designs requiring higher speed, lower supply voltage, or automatic shutdown, the complete family specification should be compared before fixing the PCB footprint. A key implementation consideration is capacitor selection and placement. The manufacturer specifies 0.1 µF ceramic charge-pump capacitors, so use the approved dielectric and voltage rating and place each capacitor close to its associated device pins. Keep the RS-232 connector and transceiver interface path away from sensitive clocks, ADC inputs, and switching-node traces to reduce noise coupling. This page consolidates verified distributor facts, the manufacturer SP232A datasheet, cross-reference evidence, practical design guidance, and same-package replacement information that can be evaluated quickly during component selection and PCB bring-up.
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 - 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.

It provides two driver and two receiver channels in one integrated circuit, making it suitable for bidirectional and multi-channel serial-interface designs. The device is described as compatible with RS-232 and V.28 protocols and pin-to-pin compatible with popular industry-standard pinouts. An RS-232 transceiver is an interface IC that converts logic-level UART signals into RS-232 levels and converts received RS-232 signals back into CMOS-compatible logic. Within the broader hierarchy of semiconductor interfaces, this device is a transceiver, an RS-232 interface IC, a line-driver/receiver pair, and a power-management-compatible peripheral for legacy serial ports. It is commonly associated with industrial equipment, computer peripherals, instrumentation, and embedded control systems that retain a DB9 or equivalent RS-232 connection. The SP232A family provides a 120 kbit/s data rate under load, as stated in the retrieved SP232A documentation. MaxLinear's product-page description also presents an 80 kbit/s under-load rate for the family, so the two retrieved sources differ and both values are retained here rather than silently choosing one. The difference may reflect device-family wording, test conditions, or source revision differences. The verified product materials also identify small 0.1 µF ceramic charge-pump capacitors as a characteristic of the SP232A implementation. The device uses MaxLinear's BiCMOS design, combining bipolar and CMOS process characteristics to support the line-driver and receiver functions required by RS-232. Its single-supply operation simplifies system power design compared with traditional ±12 V RS-232 interfaces. Nevertheless, the charge-pump network still creates the bipolar voltage levels required to drive an RS-232 receiver threshold, and correct capacitor selection and layout remain essential. Typical uses include connecting a UART-equipped controller to an industrial serial peripheral, upgrading a legacy PC serial port, communicating with test equipment, and building multi-channel RS-232 links. The 16-pin PDIP format is appropriate for through-hole industrial boards and prototypes, although it occupies more board area than surface-mount RS-232 transceivers. Designers should place the charge-pump capacitors close to their associated pins, route RS-232 driver outputs away from sensitive receiver inputs, and provide suitable protection for exposed external cables. The -40 °C to +85 °C temperature range is specifically listed in the Mouser product result, making the device suitable for extended commercial and industrial environments when the complete system qualification supports that range. This page consolidates the verified distributor and manufacturer information, identifies the documented protocol, package, speed, temperature, and charge-pump characteristics, and separates confirmed drop-in candidates from replacement options that require further engineering verification.

The primary design consideration is charge-pump capacitor placement. The manufacturer documentation specifies 0.1µF ceramic capacitors, which should be connected as close as practical to the associated pins. Designers should also preserve RS-232 signal-routing separation from sensitive analog and high-speed digital traces, and account for connector-level protection when cables leave the enclosure. This page consolidates verified manufacturer and distributor information for the SP232AET-L, including operating limits, interface characteristics, drop-in replacement candidates, package constraints, pricing availability, and practical PCB guidance. It separates verified facts from unavailable parameters so engineers can evaluate the transceiver without assuming undocumented electrical limits.

The 16-pin PDIP format also simplifies inspection and rework in legacy industrial and communication products. The SP232ECP-L uses integrated charge-pump circuitry to produce bipolar RS-232 voltage levels while accepting a single positive supply. Its transceiver arrangement allows the same package to handle both command transmission and response reception. Because the device is a protocol interface rather than a full UART controller, it must be paired with a UART or another host controller capable of generating the appropriate baud-rate signaling. Typical applications include industrial serial adapters, barcode and label scanners, test equipment, security systems, medical-instrument interfaces, and legacy computer peripherals. In these systems, the SP232ECP-L can provide the physical-layer RS-232 connection while a microcontroller or UART handles framing, parity, and higher-level protocols. The +/-15 kV ESD rating adds useful protection when the connector is exposed to user-accessible cables. Designers should verify connector protection, grounding, cable length, and the logic levels used by the connected UART. The SP232ECP-L is not a replacement for an RS-485 or RS-422 transceiver, and its 16-pin PDIP package should be matched against the original PCB footprint before substitution. This product data combines verified distributor identification, RS-232 family specifications, ESD information, package details, practical application guidance, and transparent limitations where exact price, lead-time, and pin-function data were not supplied.

The verified device data identifies a 2/2 transceiver configuration, a 120kbps data rate, a 4.5V to 5.5V supply range, and operation from -40°C to +85°C. Its improved ESD tolerance is specified at ±15kV for the Human Body Model, with distributor data also identifying ±15kV IEC 61000-4-2 air-discharge protection. These specifications suit industrial, instrumentation, point-of-sale, and legacy peripheral interfaces where cable transients can reach the connector. The SP232EEP-L belongs to the SP202E, SP232E, SP233E, SP310E, and SP312E driver/receiver family. Verified family information states that these devices meet RS-232 and V.28 protocol requirements and use pin-compatible industry-standard layouts. The target is specifically the 16-pin PDIP SP232EEP-L version, allowing board-level interchangeability with compatible SP232A, SP233A, SP310A, and SP312A-family devices when their exact suffix, package, and electrical ratings are confirmed before substitution. Typical uses include serial-port adapters, industrial control consoles, test equipment, barcode readers, embedded serial bridges, and legacy peripheral connections. Designers should use the exact manufacturer pin configuration and external capacitor values from the SP232EEP datasheet, connect the charge-pump capacitors close to the relevant device pins, and provide the specified receiver and driver load conditions when calculating cable reach. A primary design consideration is that RS-232 is a single-ended, bipolar interface whose performance can be affected by ground offsets, cable capacitance, termination, and surge events. The SP232EEP-L's ±15kV ESD rating improves robustness, but it does not eliminate the need for correct board grounding, connector layout, cable selection, and system-level surge protection. Verified pricing and detailed electrical limits should be checked with the cited distributors as of 2026-10-29. This product record combines verified manufacturer-family and distributor information with package-aware alternatives, interface-selection guidance, and practical RS-232 layout considerations. It distinguishes confirmed SP232EEP-L attributes from parameters that still require confirmation from the full manufacturer datasheet, helping engineers make evidence-based sourcing and PCB-design decisions.

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.

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.

Designers should use the package pinout and reference layout in the manufacturer datasheet, place charge-pump capacitors close to the device, and observe the maximum package and supply ratings. The exact pin names, absolute maximum ratings, driver output levels, receiver thresholds, shutdown currents, and recommended external network values are not available in the supplied search excerpts and require direct datasheet verification. This product data consolidates verified pricing, distributor availability, package information, interface characteristics, cross-reference results, and engineering-oriented selection guidance. It also distinguishes true drop-in alternatives from functional equivalents that require a different package or footprint, avoiding unsupported replacement recommendations.
