SP232ECP-L - RS-232 Transceiver, 5V, +/-15kV ESD | MaxLinear
N.º de pieza: SP232ECP-L ✓ ActivoSP232ECP-L Descripción general
An RS-232 transceiver is an interface IC that converts logic-level digital signals into RS-232 line levels and converts incoming RS-232 signals back into CMOS-compatible logic. In the broader electronics hierarchy, the SP232ECP-L belongs to the RS-232 interface family, which is part of interface ICs and serial communication semiconductors. The integrated charge pump generates the positive and negative voltage swings required by RS-232 without requiring a separate bipolar supply. This makes the device useful where the system already has a 5 V rail and only a serial communications port is needed.
Key features include operation from a single +5 V supply, two RS-232 drivers, two RS-232 receivers, compatibility with RS-232-D and ITU V.28 protocols, and improved ESD tolerance exceeding +/-15 kV for the human-body model. The wide specified operating-temperature range of 0 C to 70 C supports commercial equipment. 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.

Aplicaciones típicas
SP232ECP-L es adecuado para 6 aplicacións: Industrial serial control, Barcode and label scanners, Test and measurement instrumentation, Embedded service interfaces, Security and access systems, Legacy computer peripherals.
Industrial serial control
The SP232ECP-L fits industrial control equipment that needs a legacy RS-232 port while the controller operates from a 5 V rail. Its 2/2 transceiver arrangement supports two outgoing control or status signals and two incoming responses in the same 16-pin PDIP footprint. The integrated charge pump supplies the required RS-232 voltage levels, while the specified +/-15 kV human-body-model ESD tolerance helps protect a user-accessible connector. The 0 C to 70 C rating is appropriate for many commercial indoor systems, but it should be checked against the enclosure temperature. A UART remains responsible for baud rate, framing, parity, and protocol handling.
Recomendado
Barcode and label scanners
The SP232ECP-L can provide the physical RS-232 connection for barcode scanners, label printers, and other point-of-sale peripherals that use legacy serial protocols. Two driver and two receiver channels allow command transmission and acknowledgement data on one compact interface. Operating from a single +5 V supply simplifies integration into scanners and terminal electronics that do not provide a bipolar RS-232 rail. The +/-15 kV human-body-model ESD rating is useful when the cable is exposed to charged user contact. Designers should still confirm connector grounding, logic polarity, and the peripheral's supported baud rate before production use.
Recomendado
Test and measurement instrumentation
The SP232ECP-L is appropriate for legacy test equipment and measurement instruments that communicate with a host PC through an RS-232 port. The single +5 V supply is convenient for compact bench instruments, while the integrated charge pump eliminates the need for an external negative voltage generator. The 16-pin PDIP package is useful when maintaining older professional equipment. Its 0 C to 70 C specification covers typical indoor laboratory conditions. Engineers must verify isolation requirements, ground-loop behavior, and maximum cable length because the provided data does not specify receiver thresholds, slew rates, or isolation performance.
Recomendado
Embedded service interfaces
The SP232ECP-L can add a service or configuration port to embedded industrial equipment that has 5 V power but no native RS-232 connector. Its 2/2 channel arrangement supports diagnostic commands in one direction and telemetry or acknowledgements in the other. The DIP package is especially practical for legacy controller boards where a through-hole footprint already exists and a compact SMD redesign would be disruptive. The integrated charge pump reduces external circuitry, while the stated +/-15 kV human-body-model ESD tolerance helps manage electrostatic exposure at an accessible service connector. Firmware engineers should implement timeout and framing behavior appropriate to the peripheral protocol.
Recomendado
Security and access systems
The SP232ECP-L can support RS-232 connections in access-control readers, alarm panels, and legacy security equipment that uses a 5 V control board. The two transmitters and two receivers permit bidirectional command and status communication, which is common in access-control systems. Its enhanced +/-15 kV human-body-model ESD tolerance provides a useful level of connector protection when cables are repeatedly connected by installers or users. The device itself is not an isolated interface, so cabinet grounding and potential differences between connected equipment must be evaluated. Its 0 C to 70 C commercial temperature range also requires consideration in outdoor or unconditioned installations.
Recomendado
Legacy computer peripherals
The SP232ECP-L is suited to maintaining legacy computer peripherals, service adapters, and industrial data-collection equipment that still uses RS-232. Its 16-pin PDIP package allows straightforward use in older through-hole designs, and the single +5 V supply is compatible with many established controller boards. The 2/2 transceiver arrangement supports both control outputs and status inputs without requiring separate driver and receiver packages. The specified +/-15 kV human-body-model ESD tolerance is valuable in desktop and laboratory environments where cables are frequently handled. Before replacing an existing IC, confirm that shutdown, enable, supply, and receiver-threshold behavior are identical in the relevant datasheet revision.

Notas de diseño
Use the manufacturer pinout and footprint drawings before replacing SP232ECP-L in an existing board. The verified data confirms a 16-pin PDIP format, but it does not provide the individual pin names or exact dimensions. Confirm pin-1 orientation, package row spacing, and any exposed board-level differences before inserting the replacement. Keep the transceiver close to the connector so transient energy is not coupled into unrelated logic.
The SP232ECP-L uses a single +5 V supply and an integrated charge pump to create the bipolar RS-232 signal levels. Place the device-side bypass capacitor close to its supply and ground pins according to the manufacturer application circuit, and keep the charge-pump return current within the intended ground path. The supplied data does not state the recommended capacitor values or charge-pump switching details, so those values must be obtained from the manufacturer datasheet.
Do not assume that every SP232E suffix is automatically interchangeable. The supplied cross-reference results show related SP232E-family parts, but they do not provide complete electrical and pin-function tables for each suffix. Before substitution, compare supply voltage, receiver thresholds, enable or shutdown behavior, temperature grade, ESD rating, and PDIP pinout. Also verify that the connected UART logic levels and signal polarities are compatible.
RS-232 driver outputs are relatively slow compared with many modern digital interfaces, but they can still radiate noise when the cable is long or poorly terminated. Route driver and receiver traces away from sensitive analog and clock networks, return the cable shield to chassis ground according to the equipment architecture, and avoid long unprotected stubs. If the connector is user accessible, retain the specified +/-15 kV human-body-model ESD capability and follow the manufacturer protection-circuit guidance.
