SP3232EHEY-L/TR - 460 kbps RS-232 Transceiver | MaxLinear

The MaxLinear SP3232EHEY-L/TR is a 2-driver, 2-receiver RS-232 transceiver operating from a 3 V to 5.5 V single supply, supporting data rates up to 460 kbps in a 16-pin TSSOP package. The device includes a high-efficiency charge-pump supply and enhanced ESD protection rated to ±15 kV under the IEC human-body-model condition. Its integrated level conversion converts TTL/CMOS logic levels to and from RS-232 levels without requiring a separate supply for the interface rails. An RS-232 transceiver is a semiconductor interface device that bridges a digital logic system and a serial communications link using RS-232 voltage signaling. Each transceiver channel combines a line driver, which converts logic signals into RS-232 output levels, with a receiver, which converts incoming RS-232 signals into logic-compatible levels. In the broader hierarchy, the SP3232EHEY-L/TR belongs to the interface-controller class, specifically the RS-232 driver/receiver and transceiver family within integrated interface ICs. The SP3232E series supports operation from a single 3.3 V supply while producing the positive and negative voltage levels required for conventional RS-232 communication. According to the MaxLinear manufacturer datasheet, its charge-pump supply requires only 0.1 µF capacitors in 3.3 V operation. The 2/2 driver and receiver arrangement provides two independent communications channels, while the 460 kbps maximum signaling rate supports common point-to-point serial links, embedded equipment, and legacy peripheral interfaces. The enhanced protection is particularly valuable in industrial and instrumentation environments where cables can be longer and more exposed than in a protected desktop enclosure. The device is specified for true EIA/TIA-232-F operation from a supply as high as 5.5 V and can interoperate with RS-232 equipment powered from a source as low as 2.7 V. Its internal charge-pump architecture reduces the number of external bulk capacitors while preserving bipolar RS-232 output levels. Typical applications include data acquisition equipment, industrial controllers, portable test instruments, point-of-sale terminals, and embedded systems that retain an RS-232 service or communications port. The device can also pair with a host UART or microcontroller to provide a standards-compliant physical interface for legacy equipment. Designers should treat the cable, ground reference, connector, and logic levels as parts of the complete communication path rather than relying only on the IC specification. A key design consideration is ensuring that the host-side interface levels match the selected UART and that unused driver or receiver channels are handled according to the manufacturer pin descriptions. Power-supply decoupling, charge-pump capacitor placement, and signal routing should follow the recommended layout in the manufacturer datasheet. ESD protection helps manage cable transients, but it does not replace proper grounding, shielding, or external surge protection in severe industrial environments. This product page combines the exact electrical ratings, package information, pin-location guidance, verified drop-in candidates, and practical interface-layout considerations for SP3232EHEY-L/TR. It also distinguishes genuine same-footprint replacements from functionally similar devices that use different packages, allowing engineers to evaluate compatibility before modifying an existing RS-232 design.

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 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.

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.
