SP232EEN-L Descripción general
An RS-232 transceiver is an interface IC that converts logic-level digital signals into RS-232 line signals and converts received line signals back into digital logic. The SP232E family belongs to the broader transceiver hierarchy: RS-232 interface IC, communications interface, interface IC, and integrated circuit. Its two-driver, two-receiver arrangement supports full-duplex serial links in industrial controls, test equipment, and embedded systems.
The verified data identifies a single-supply architecture, ESD tolerance of +/-15 kV, and compatibility with RS-232D and ITU V.28 protocols. The 16-SOIC package is surface mount and is suitable for compact PCB assemblies. The 240 kbps data rate provides useful margin for many control and instrumentation links, while receiver hysteresis helps reject small noise perturbations around the receive threshold.
Typical uses include RS-232 service ports, industrial serial adapters, embedded-controller links, and laboratory equipment. The device should be placed near the connector or logic interface it serves, with protection and grounding designed for the external cable environment. Because RS-232 uses single-ended bipolar signaling, cable routing, common-mode conditions, and ESD protection remain important.
The SP232EEN-L is the -L packaging/orderable variant identified by the verified distributor listings, while SP232EEN-L/TR is a tape-and-reel ordering variant. Do not substitute a different package or pinout without checking the manufacturer datasheet. This page combines verified product specifications, distributor information, cross-reference results, and practical design guidance for engineering selection.

Aplicaciones típicas
SP232EEN-L es adecuado para 6 aplicacións: Industrial RS-232 Service Port, Embedded Controller Communication, Test and Measurement Equipment, Data Acquisition and Control Systems, Legacy Computer Serial Adapter, Communication Port in Harsh Environment.
Industrial RS-232 Service Port
The SP232EEN-L fits industrial service and configuration ports that need a compact, single-supply RS-232 interface. Its two drivers and two receivers support full-duplex communication, while the verified 240 kbps rate is suitable for many command and diagnostic links. The 4.5 V to 5.5 V supply range and -40C to +85C operating range align with common industrial equipment architectures. Place the transceiver between the host UART and a protected DB9 or terminal connector. The key design consideration is cable-side grounding and ESD protection, especially when the port is exposed to user-accessible cabling.
Recomendado
Embedded Controller Communication
Use the SP232EEN-L when an embedded controller needs to bridge a CMOS/TTL UART to an RS-232 port. The dual-driver and dual-receiver arrangement allows transmit and receive paths to coexist in one package, reducing board area compared with separate line-driver and receiver ICs. Its 16-SOIC format is compatible with standard surface-mount assembly, and the verified -40C to +85C range covers many embedded and industrial environments. Check the host UART voltage levels, confirm grounding, and use the manufacturer datasheet for the exact charge-pump and bypass components.
Recomendado
Test and Measurement Equipment
The SP232EEN-L is appropriate for laboratory instruments that expose a legacy RS-232 control or data port. The 240 kbps rate is useful for command traffic, status reporting, and instrument automation, while 500 mV receiver hysteresis can improve tolerance to small signal perturbations around the receive threshold. The single +5 V supply simplifies integration with instrument logic that already operates from 5 V. Keep the connector-side traces short where practical, provide a defined ground reference, and validate the complete cable and grounding system because RS-232 performance is system-dependent.
Recomendado
Data Acquisition and Control Systems
The SP232EEN-L can connect a data-acquisition controller or industrial control module to an RS-232 master. Two drivers support full-duplex command and response traffic, and the 240 kbps rate accommodates many short-distance control protocols. The -40C to +85C specification supports use across temperature-controlled equipment, but cable length and noise immunity must be verified for the intended installation. Add connector-side surge and ESD protection when the port connects to external equipment, and maintain a low-impedance ground path between the transceiver and the system reference.
Recomendado
Legacy Computer Serial Adapter
The SP232EEN-L is suitable for adding a legacy RS-232 port to a modern controller or embedded board when the original interface used a two-driver, two-receiver topology. Its 16-SOIC package is compact and widely handled by surface-mount manufacturing, while the 5 V single-supply operation fits many legacy peripheral designs. Confirm the connector pinout, cable length, and signal polarity because RS-232 implementations can vary at the system level. The IC handles logic conversion, but it does not replace external connector protection, isolation, or cable shielding.
Recomendado
Communication Port in Harsh Environment
The SP232EEN-L can be used in communication ports that require a -40C to +85C operating range and enhanced ESD tolerance. The verified source identifies +/-15 kV ESD capability, making the device a reasonable starting point for exposed RS-232 ports, but the rating does not eliminate the need for system-level protection. For cable-connected equipment, place protection close to the connector, control ground current, and verify isolation requirements. The 240 kbps rate can also reduce the number of high-speed edges that need careful routing in long or electrically noisy installations.

Notas de diseño
Keep the SP232EEN-L close to the RS-232 connector and separate logic-side nets from cable-side nets as far as practical. Maintain a continuous ground reference and route the transceiver interface according to the manufacturer datasheet layout. The verified data does not specify trace-length or capacitor values, so those details must be taken from the official application guidance rather than estimated.
Do not confuse the SP232EEN-L orderable variant with the SP232EEN-L/TR tape-and-reel variant or with a different RS-232 family member that may have different electrical details. Confirm the package, pinout, temperature range, supply limits, and lifecycle status before substitution. Cross-reference listings indicate compatibility candidates but are not a substitute for the manufacturer datasheet.
RS-232 is a single-ended interface, so ground current and cable placement can affect noise immunity. Use a low-impedance ground connection between the transceiver and system reference, keep external cable routing away from sensitive logic where possible, and add connector-side protection when cables are user accessible. The +/-15 kV ESD specification is an IC capability, not a guarantee that every exposed system is adequately protected.
Design the 5 V rail within the verified 4.5 V to 5.5 V supply range and account for startup, transient, and connector-load conditions at the system level. The supplied data does not provide the internal charge-pump capacitor recommendation or a complete power-consumption table, so use the MaxLinear family datasheet for those values. Validate the rail at the IC pins rather than only at the power supply connector.
Información de cumplimiento
The supplied verified snippets do not provide compliance declarations for RoHS, REACH, lead-free status, halogen-free status, or conflict minerals. The part is an interface IC rather than an automotive-qualified device in the supplied data.
