SP232ACN-L - Dual RS-232 Transceiver | MaxLinear
MPN: SP232ACN-L ✓ সক্রিয়SP232ACN-L সারাংশ
An RS-232 transceiver is a semiconductor interface that converts between TTL/CMOS logic levels and the voltage-defined, inverting signals used on an RS-232 link. Within the broader hierarchy of interface ICs, it sits between a host controller or UART and an external serial connector. The SP232ACN-L combines driver and receiver functions in one package, reducing the component count and board area needed for two-way RS-232 communication.
Key verified features include single +5 V operation, operation from 4.5 V to 5.5 V, two drivers, two receivers, and a maximum data rate of 120 kbps under load. The manufacturer describes the SP232A family as pin-to-pin compatible with popular industry-standard pinouts and suitable for commercial applications. The charge-pump function supports operation with small ceramic capacitors rather than requiring large electrolytic capacitors.
The SP232A family uses a BiCMOS design and implements enhanced RS-232 line-driver and receiver functions. In a typical UART connection, the host TX signal enters a driver and becomes an RS-232-level signal, while an incoming RS-232 signal passes through a receiver and becomes a CMOS-compatible signal for the host. The interface is appropriate when the link requires the established RS-232 voltage levels rather than short-distance TTL signaling.
Typical uses include industrial serial consoles, instrumentation, data acquisition, point-of-sale equipment, embedded debug ports, and legacy computer peripherals. In these systems, the transceiver bridges a low-voltage UART or processor port to an external RS-232 connector. Cable length, grounding, shielding, and connector-level ESD protection remain important system considerations; the IC does not eliminate the need for a suitable connector and protection network.
A practical design tip is to place the charge-pump capacitors close to their marked pins and keep the RS-232 traces short and isolated from sensitive analog or high-speed digital paths. The selected 16-SOIC footprint is suitable for conventional surface-mount assembly, but the exact pin names and package details should be confirmed against the manufacturer datasheet before layout.
This product record combines verified distributor specifications, manufacturer-family information, cross-reference results, practical interface design notes, and availability-focused commercial guidance for engineers evaluating the SP232ACN-L.

সাধারণ ব্যবহার
SP232ACN-L এর জন্য উপযুক্ত 6 অ্যাপ্লিকেশনs: Industrial Serial Console, Data-Acquisition Equipment, Embedded Debug and Service Port, Point-of-Sale Terminal Interface, Instrumentation and Test Equipment, Legacy Computer Peripheral Connection.
Industrial Serial Console
The SP232ACN-L is a good fit for an industrial console because it combines two RS-232 drivers and two receivers in a single 16-SOIC package and operates from a single 4.5 V to 5.5 V supply. It supports the RS-232 and V.28 protocols identified in the verified manufacturer information, with data rates up to 120 kbps under load. A microcontroller UART can drive the transmitter inputs, while received RS-232 levels are converted back to logic levels. The 0.1 µF charge-pump capacitors should be placed close to the IC, and the external connector, grounding, and cable return path require normal industrial serial-interface design review.

Data-Acquisition Equipment
For laboratory and data-acquisition equipment, the SP232ACN-L provides a compact bridge between a control processor and an external RS-232 instrument. The two-driver, two-receiver arrangement can support more than one serial endpoint or provide separate transmit and receive paths. Its verified 5 V nominal supply and 0 °C to 70 °C commercial temperature range fit many indoor instrument designs, while the 120 kbps-under-load specification supports moderate-speed command and status traffic. The design should preserve signal integrity with short traces, controlled connector routing, and verified charge-pump capacitor placement.

Embedded Debug and Service Port
The SP232ACN-L can be used in embedded systems that expose a service, configuration, or debug port through legacy RS-232. Its dual-channel structure allows a compact implementation with multiple driver and receiver endpoints, and the 120 kbps-under-load capability is suitable for many UART configuration protocols. The 16-SOIC package is compatible with conventional surface-mount assembly, and the single 5 V supply simplifies integration with systems that already provide 5 V logic power. Engineers should still account for connector-level ESD, grounding, cable length, and any isolated or protected interface requirement.

Point-of-Sale Terminal Interface
Point-of-sale equipment often needs a straightforward host-to-peripheral RS-232 link for printers, scanners, or service connectors. The SP232ACN-L provides two transmit and two receive functions, allowing a compact interface block around a UART without selecting separate driver and receiver packages. Its 4.5 V to 5.5 V supply range aligns with many 5 V systems, and the 120 kbps-under-load specification is more than adequate for many transaction and configuration messages. Layout should keep RS-232 traces away from sensitive logic and include suitable connector protection for cables that leave the enclosure.
সুপারিশকৃত
Instrumentation and Test Equipment
The SP232ACN-L is suitable for test and measurement equipment that uses RS-232 for remote commands, calibration data, or status reporting. Its dual transmit and receive channels provide flexibility for connecting a controller to a peripheral, while the commercial 0 °C to 70 °C rating is appropriate for many indoor instruments. The device operates from a single 5 V supply and uses small 0.1 µF ceramic charge-pump capacitors according to the verified family description. For reliable operation, verify grounding and return-current paths and use the manufacturer’s pin and capacitor guidance before releasing the PCB layout.
সুপারিশকৃত
Legacy Computer Peripheral Connection
The SP232ACN-L can bridge a modern controller to a legacy RS-232 peripheral while retaining a familiar 16-SOIC footprint and 5 V supply arrangement. Its two drivers and two receivers make it possible to implement a full-duplex serial port in a compact circuit. The verified product data identifies compatibility with industry-standard RS-232 pinouts, but designers should still compare the exact pin map and electrical limits with the peripheral interface. Cable length, grounding, shielding, and connector selection can determine whether a nominally correct transceiver produces reliable field operation.

ডিজাইন নোট
Decouple the single 5 V supply close to the SP232ACN-L with the capacitor network recommended by the manufacturer datasheet. The verified device description emphasizes operation from 4.5 V to 5.5 V and use of 0.1 µF ceramic charge-pump capacitors. Keep the charge-pump loop compact, verify capacitor voltage rating and tolerance, and avoid routing the supply return through long RS-232 cable paths.
Place the charge-pump capacitors at the pins identified in the manufacturer documentation and keep RS-232 traces away from clocks, ADC inputs, and sensitive analog nodes. The device supports up to 120 kbps under load, but practical performance also depends on cable capacitance, grounding, connector geometry, and return-path continuity. Use a controlled ground reference and avoid long stubs between the transceiver and connector.
Do not assume that any MAX232 suffix is automatically interchangeable with SP232ACN-L. Check the exact 16-SOIC footprint, pin names, supply range, temperature grade, charge-pump capacitor values, and logic polarity. Also verify that the ordering suffix used by the distributor corresponds to the required package and delivery format; SP232ACN-L and SP232ACN-L/TR may represent ordering variants of the same device family.
