SP3232ECN-L/TR - 120 kbps RS-232 Transceiver | MaxLinear (Tape & Reel)
The MaxLinear SP3232ECN-L/TR is a 2-driver, 2-receiver RS-232 transceiver rated for data rates up to 120 kbps and operating from a single 3 V to 5.5 V supply. The device is packaged in a 16-pin narrow SOIC and is intended for portable and handheld equipment that requires true RS-232 electrical levels from a low-voltage logic supply. An RS-232 transceiver is an interface integrated circuit that combines line drivers, line receivers, and the charge-pump circuitry needed to generate the bipolar voltage swings required by the EIA/TIA-232 standard. Within the interface hierarchy, the SP3232ECN-L/TR belongs to the RS-232 transceiver family, which sits below interface transceivers and above individual drivers and receivers. The SP3232ECN-L/TR uses a high-efficiency charge-pump supply that requires only 0.1 uF capacitors during 3.3 V operation. This allows the transceiver to operate from 3 V to 5.5 V while maintaining true RS-232 performance. Its 2/2 channel arrangement provides two transmit paths and two receive paths in one package, reducing board area compared with separate driver and receiver ICs. The E-qualified version also provides enhanced electrostatic-discharge protection of up to plus or minus 15 kV under both the IEC 61000-4-2 system and the Human Body Model. The operating temperature range shown by distributor data is 0 C to 70 C. This combination of low supply voltage, integrated charge pump, and reinforced ESD protection makes the part useful in equipment exposed to electrically noisy or physically connected environments. Typical applications include notebook and palmtop computer serial ports, industrial control panels, point-of-sale terminals, data-acquisition equipment, and service interfaces for embedded systems. The 120 kbps signaling rate is appropriate for legacy RS-232 links carrying configuration commands, diagnostic data, and control traffic rather than continuous high-speed bulk transfers. When designing the circuit, verify the charge-pump capacitor values, driver and receiver connection details, and interface protection requirements against the manufacturer data sheet. Keep RS-232 driver outputs away from sensitive analog inputs, provide controlled return paths, and consider adding external surge protection when a cable can leave the enclosure. This page consolidates manufacturer and distributor information, package details, commercial availability, drop-in replacement options, application guidance, and practical design notes into one engineering reference for evaluating the SP3232ECN-L/TR in new and existing serial-interface designs.

MaxLinear, Inc. SP3232ECP-L is a +3.0 V to +5.5 V RS-232 transceiver containing two drivers and two receivers in a 16-pin DIP package. It supports data rates up to 120 kbps and uses an integrated charge-pump power supply that requires only 0.1 uF capacitors for 3.3 V operation. The device also provides a low-power shutdown mode with a 1 uA supply current while the receivers remain active. An RS-232 transceiver is an interface IC that converts logic-level signals between a host or controller and a serial port using differential, bipolar voltage levels. The SP3232ECP-L belongs to the RS-232 interface transceiver hierarchy, combining transmitter, receiver, voltage conversion, and power-management functions in one package. This integration is useful in portable equipment, industrial controllers, and embedded systems that need a compact, single-supply RS-232 connection. Key features include a 3 V to 5.5 V operating supply range, two transmit channels, two receive channels, and a maximum data rate of 120 kbps. The efficient charge-pump architecture generates the required bipolar RS-232 levels without an external switched power-supply circuit. A 0.1 uF charge-pump capacitor value in 3.3 V operation reduces external component count, while the 16-pin DIP package supports conventional through-hole assembly. The SP3232E family architecture uses on-chip charge pumps to develop positive and negative voltage rails required for compliant RS-232 signaling. The charge-pump capacitors must be connected close to their associated pins to minimize switching noise and maintain stable operation. The shutdown function can reduce supply current to 1 uA when the receivers are active, making the device suitable for systems that need low standby consumption without continuously disabling inbound serial communication. Typical applications include RS-232 ports on portable computers, point-of-sale terminals, industrial control equipment, test systems, and embedded serial adapters. The device is particularly appropriate where a 3.3 V system needs true RS-232 levels rather than logic-level TTL signaling. It can also simplify existing designs that use a higher-voltage supply, provided the host voltage, cable length, grounding, and signal-rate requirements remain compatible. Designers should follow the manufacturer datasheet for the exact pin assignments, charge-pump capacitor configuration, receiver enable behavior, and recommended decoupling. Place the charge-pump capacitors and receiver-input protection network according to the specified layout, use a suitable bypass capacitor at the supply pin, and confirm that the connected cable and logic levels match the system's electrical requirements. This page consolidates the verified electrical characteristics, package information, application guidance, and design considerations for engineers evaluating the SP3232ECP-L. It also distinguishes confirmed drop-in alternatives from unavailable or functionally different options so that replacement decisions are based on package and pin compatibility rather than name similarity alone.
SP3232ECT-L - 120kbps RS-232 Transceiver | MaxLinear
The MaxLinear SP3232ECT-L is a true RS-232 transceiver with two drivers and two receivers, a minimum data rate of 120 kbps, a 3 V to 5.5 V supply range, and a 16-pin WSOIC package. It is designed for portable and handheld equipment that requires bidirectional RS-232 communication from a single low-voltage supply. An RS-232 transceiver is an interface IC that converts logic-level signals between a host or controller and RS-232 lines. The transceiver hierarchy includes interface IC, communications interface, and signal-conditioning semiconductor. Unlike TTL or CMOS serial signals, RS-232 uses voltage levels and signaling rules suited to longer-distance, point-to-point links. The SP3232ECT-L integrates the line driver and receiver functions needed to bridge that physical interface. A principal feature is the integrated high-efficiency charge-pump power supply. According to the manufacturer datasheet, the charge pump permits true RS-232 operation from a single 3 V to 5.5 V supply and requires only 0.1 µF capacitors in 3.3 V operation. This topology raises the supply to the voltage levels required by the RS-232 drivers without requiring a separate negative supply rail. The device supports a minimum 120 kbps data rate and provides two transmit channels plus two receive channels. That arrangement suits equipment requiring more than one serial link, such as a local-control bus, service interface, or legacy peripheral connection. Its true RS-232 interface is intended for portable computers, handheld terminals, industrial equipment, and other embedded systems that must interoperate with established RS-232 ports. Typical applications include configuration-port links, handheld test equipment, point-of-sale systems, industrial controllers, and service interfaces for installed equipment. The integrated charge pump reduces external power-supply complexity, while the 16-pin WSOIC package supports compact surface-mount assembly. Because RS-232 is a point-to-point interface, each driver should feed one receiver and unused channels should be handled according to the manufacturer recommendations. The primary design consideration is correct charge-pump capacitor placement. Place the required 0.1 µF capacitors close to their associated supply and charge-pump pins, maintain short return paths, and provide adequate ground-plane continuity. Account for the additional supply current drawn by the charge pump when calculating power capacity, especially in portable equipment operating from a battery-derived 3.3 V rail. This product page consolidates the exact SP3232ECT-L operating facts, package information, verified source links, sourcing guidance, and engineering-oriented replacement analysis. It is intended to help designers evaluate the interface function, board-level implementation, and procurement requirements without relying on a generic RS-232 overview.

The device is supplied in tape-and-reel packaging for automated assembly. An RS-232 transceiver is an interface IC that combines differential line drivers and receivers for point-to-point serial communication. It belongs to the transceiver and driver/receiver hierarchy within interface ICs, translating low-voltage digital logic levels into RS-232-compatible levels and converting received signals back into digital logic. This bidirectional level conversion allows equipment such as computers, test instruments, industrial controllers, and portable devices to communicate with legacy RS-232 equipment. The SP3232E series includes an efficient on-chip charge-pump supply, allowing true RS-232 operation from a single 3 V to 5.5 V rail. The manufacturer identifies the SP3232E family as meeting true EIA/TIA-232-F requirements from a supply as high as 5.5 V. A shutdown mode provides 1 µA low-power operation with receivers active, making the device useful in battery-powered portable equipment where unused drivers can be disabled without losing incoming data. The integrated 2/2 channel arrangement supports two RS-232 links through one compact IC. The 16-SOIC package is significantly smaller than most legacy DB9 connector implementations and is suitable for compact embedded products. Its 120 kbit/s minimum rate under full load is appropriate for serial console links, configuration interfaces, point-of-sale equipment, industrial service ports, and legacy peripheral connectivity rather than high-speed storage protocols. Typical uses include portable computers and handheld terminals, because the low-voltage supply and low-power shutdown suit constrained systems. The part can also bridge modern UART logic to RS-232 equipment, provide console access in industrial equipment, and support service interfaces where legacy compatibility remains necessary. The 3 V to 5.5 V operating range permits direct use from both 3.3 V and 5 V systems. Designers should follow the manufacturer’s recommended charge-pump capacitor network, place it close to the device, and provide the specified input and output bypass capacitance. Verify signal levels against the selected logic supply, keep RS-232 drivers away from sensitive analog circuitry, and review the EN and shutdown functions when power sequencing matters. Confirm the complete pin description and exposed-pad requirements against the current manufacturer datasheet before layout release.

It operates from a single 3.3 V to 5.5 V supply and supports true RS-232 signal levels, making it suitable for portable equipment and systems that need bidirectional serial communication over longer distances than a logic-level interface can provide. An RS-232 transceiver is an interface IC that converts between single-ended logic-level signals and the bipolar voltage levels defined by the RS-232 standard. The transmitter raises and inverts data signals for transmission, while the receiver converts incoming bipolar signals into CMOS-compatible logic. A dual-transceiver device provides two independent communication paths and is commonly used in console ports, data acquisition equipment, instrumentation, and embedded control systems. The SP3232E family uses an on-chip charge-pump supply and associated external capacitors to generate the positive and negative voltages required for true RS-232 operation. MaxLinear states that the SP3232E charge pump can operate with only 0.1 uF capacitors in 3.3 V systems. This capacitor requirement helps reduce board area while preserving the voltage levels needed by RS-232 receivers and drivers. The SP3232EEP-L combines the electrical functions of two RS-232 transmitters and two RS-232 receivers in one device. Its 16-pin PDIP format is suitable for conventional through-hole assembly, prototyping, repair work, and industrial or legacy control equipment. Because the package uses through-hole leads, it also provides generous mechanical spacing and is generally easier to inspect or rework than a fine-pitch surface-mount package. Typical applications include RS-232 console connections, laboratory and test equipment, industrial controller interfaces, configuration ports, and embedded systems that communicate with older peripherals. The two-driver, two-receiver organization allows simultaneous transmit and receive activity on each channel where the connected equipment supports full-duplex RS-232 communication. Design the charge-pump capacitor network with the values and layout specified in the manufacturer datasheet. Keep the transceiver close to the connector, provide a common ground path between the systems, route the differential charge-pump capacitor connections away from sensitive analog circuitry, and confirm that the selected connector and cable satisfy the intended RS-232 application. This product page combines the device architecture, package information, application guidance, sourcing workflow, and a structured list of datasheet and cross-reference resources. It also distinguishes confirmed drop-in substitutions from candidates that require pinout, package, and electrical verification before being used in a replacement design.
