SP232ACN-L/TR 概要
An RS-232 transceiver is an interface IC that converts logic-level signals into balanced, single-ended RS-232 line signals and converts received line signals back into logic levels. In the broader electronics hierarchy, it belongs to the communications-interface class, then to the RS-232 interface family and ultimately to interface semiconductors. This makes it suitable for connecting TTL or CMOS logic systems to legacy serial ports, industrial equipment, test systems, and embedded control products.
The SP232A family emphasizes compatibility with standard RS-232 pinouts, small ceramic charge-pump capacitors, and commercial-temperature operation. The verified manufacturer description identifies two drivers and two receivers, operation from a single +5V supply, and a data rate of 120kbps under load. Its 16-SOIC package supports conventional surface-mount PCB assembly, while the /TR ordering code identifies the tape-and-reel shipping format.
The interface uses charge-pump circuitry to generate the positive and negative RS-232 voltage levels needed by the drivers from a single supply. Because RS-232 is a single-ended, bipolar signaling standard, the transceiver is useful where longer cable runs or greater noise tolerance are needed compared with ordinary TTL-level serial links. The device must still be paired with correct protection, grounding, and signal-integrity practices in the complete system.
Typical applications include RS-232 ports in embedded systems, programmable-logic or microcontroller debug communications, laboratory instrumentation, industrial controllers, barcode and test equipment, and legacy peripheral connections. The 120kbps rate is suitable for moderate-speed serial links, while the 2/2 configuration allows two bidirectional channels in one package.
When placing the device, keep the RS-232 connector-side traces short where practical, provide the charge-pump capacitors required by the manufacturer, and observe the exact pinout and supply decoupling arrangement. Verify line protection and ESD requirements at the connector because the interface IC does not eliminate the need for an external protection strategy.
This product page consolidates the verified distributor and manufacturer data, identifies same-footprint alternatives, and separates known electrical facts from parameters that require application-specific confirmation. It is intended to support component selection and early board planning rather than replace the complete manufacturer datasheet.

主な用途
SP232ACN-L/TR の用途: 6 件s: Embedded RS-232 Debug Port, Industrial Controller Connectivity, Laboratory Test Equipment, Legacy Peripheral Upgrade, Point-of-Sale and Data Collection Equipment, Instrumentation and Measurement Control.
Embedded RS-232 Debug Port
The SP232ACN-L/TR fits a legacy debug or configuration port in an embedded controller because it combines two drivers and two receivers with a 120kbps data rate under load. A microcontroller or programmable-logic device can connect through its logic-level pins to a protected RS-232 connector. The 4.5V to 5.5V supply range is convenient for conventional +5V logic, while the 16-SOIC package keeps the interface compact. The main design consideration is confirming input thresholds and timing from the full datasheet rather than assuming compatibility solely from the RS-232 label.
おすすめ
Industrial Controller Connectivity
The SP232ACN-L/TR can connect a controller board to legacy RS-232 equipment when the installation remains within the verified 0 C to +70 C commercial-temperature range. Its 2/2 organization supports two communication channels, and the 120kbps rate is appropriate for configuration, status, and command traffic rather than high-bandwidth data. Designers should add connector-side surge and ESD protection because the transceiver itself is not a complete industrial isolation or surge-protection solution. Cable routing, grounding, and baud-rate margin also need validation in the installed system.
おすすめ
Laboratory Test Equipment
The two-driver, two-receiver SP232ACN-L/TR arrangement is useful for RS-232 control and measurement links in laboratory equipment. A test instrument can use one channel for commands and another for status or synchronization, while the 120kbps rate is suitable for many legacy instrument protocols. The single 5V supply and 16-SOIC footprint simplify board integration beside TTL/CMOS control logic. Engineers should verify the exact receiver thresholds, driver slew behavior, and external capacitor values against the official datasheet before enabling long cables or high-noise test environments.
おすすめ
Legacy Peripheral Upgrade
A modern controller can add an RS-232 port with the SP232ACN-L/TR when an existing enclosure, cable, or peripheral uses the standard bipolar serial interface. The device's 2/2 arrangement can preserve compatibility with equipment that expects both transmit and receive lines, while the 16-SOIC package supports surface-mount assembly. Migration effort should focus on connector pinout, logic polarity, supply rails, and charge-pump capacitor values. Do not rely on a cross-reference listing alone; compare the complete manufacturer pin and electrical tables before production release.
おすすめ
Point-of-Sale and Data Collection Equipment
The SP232ACN-L/TR is appropriate for low-to-moderate-speed serial connections in point-of-sale terminals, printers, scanners, and data-collection equipment that still exposes an RS-232 port. Its 120kbps rated rate can carry transaction traffic and control commands, while the dual-channel arrangement supports bidirectional equipment communication. The single +5V supply helps simplify integration with legacy logic. In real installations, add external protection at the connector and verify cable length, grounding, and electromagnetic-immunity requirements rather than treating the IC as a complete surge barrier.
おすすめ
Instrumentation and Measurement Control
The SP232ACN-L/TR can provide a compact RS-232 control interface for measurement instruments that use older serial protocols. Two drivers and two receivers allow the instrument to accept commands and return measurements over separate logical directions, while the 120kbps capability is suitable for many low-speed telemetry streams. The 4.5V to 5.5V operating range aligns with legacy +5V control electronics. For bench or rack equipment, place the transceiver near the connector only after considering ESD, isolation, grounding, and cable transient requirements.

設計ノート
Use a 4.5V to 5.5V single supply and place local decoupling close to the supply pins according to the manufacturer layout guidance. The RS-232 drivers generate bipolar output levels through internal charge-pump circuitry, so supply noise can appear on the line. Confirm bypass capacitance, capacitor voltage rating, and the exact charge-pump capacitor connections in the datasheet rather than copying values from a different SP232 variant.
Keep the charge-pump capacitor loop compact and follow the manufacturer's recommended component placement. Separate noisy charge-pump routing from sensitive receiver inputs where practical, and route the connector-side differential pair as a controlled pair to minimize asymmetric pickup. The interface is only one part of the signal path: add the required series impedance, protection devices, chassis or signal-ground arrangement, and connector shield strategy at the board edge.
Do not treat RS-232 as TTL logic at the connector. The transceiver performs logic-to-bipolar line conversion, and the verified device uses a single +5V supply to create the required positive and negative output levels. Confirm TX/RX polarity, connector DTE/DCE assumptions, baud rate, cable length, and ground connection before connecting legacy equipment. Also verify whether the application requires external surge or ESD protection beyond the stated interface-device ratings.
コンプライアンス情報
