SP232EEP-L - 120kbps ±15kV RS-232 Transceiver | MaxLinear
部品番号: SP232EEP-L ✓ 生産中SP232EEP-L 概要
An RS-232 transceiver is an interface IC that converts logic-level UART signals into differential, bipolar RS-232 line signals and converts received RS-232 signals back into CMOS-compatible digital levels. Within the broader hierarchy, an RS-232 transceiver is a serial-interface IC, an interface IC, and ultimately a semiconductor designed to connect data-processing equipment to a wired communications port. The SP232EEP-L combines the driver and receiver functions in one package while requiring external charge-pump capacitors.
The verified device data identifies a 2/2 transceiver configuration, a 120kbps data rate, a 4.5V to 5.5V supply range, and operation from -40°C to +85°C. Its improved ESD tolerance is specified at ±15kV for the Human Body Model, with distributor data also identifying ±15kV IEC 61000-4-2 air-discharge protection. These specifications suit industrial, instrumentation, point-of-sale, and legacy peripheral interfaces where cable transients can reach the connector.
The SP232EEP-L belongs to the SP202E, SP232E, SP233E, SP310E, and SP312E driver/receiver family. Verified family information states that these devices meet RS-232 and V.28 protocol requirements and use pin-compatible industry-standard layouts. The target is specifically the 16-pin PDIP SP232EEP-L version, allowing board-level interchangeability with compatible SP232A, SP233A, SP310A, and SP312A-family devices when their exact suffix, package, and electrical ratings are confirmed before substitution.
Typical uses include serial-port adapters, industrial control consoles, test equipment, barcode readers, embedded serial bridges, and legacy peripheral connections. Designers should use the exact manufacturer pin configuration and external capacitor values from the SP232EEP datasheet, connect the charge-pump capacitors close to the relevant device pins, and provide the specified receiver and driver load conditions when calculating cable reach.
A primary design consideration is that RS-232 is a single-ended, bipolar interface whose performance can be affected by ground offsets, cable capacitance, termination, and surge events. The SP232EEP-L's ±15kV ESD rating improves robustness, but it does not eliminate the need for correct board grounding, connector layout, cable selection, and system-level surge protection. Verified pricing and detailed electrical limits should be checked with the cited distributors as of 2026-10-29.
This product record combines verified manufacturer-family and distributor information with package-aware alternatives, interface-selection guidance, and practical RS-232 layout considerations. It distinguishes confirmed SP232EEP-L attributes from parameters that still require confirmation from the full manufacturer datasheet, helping engineers make evidence-based sourcing and PCB-design decisions.

主な用途
SP232EEP-L の用途: 6 件s: Industrial Serial Control Console, Point-of-Sale Terminal Interface, Barcode Reader and Peripheral Connectivity, Legacy Computer Serial Adapter, Test and Measurement Instrumentation, Embedded Serial Port Bridge.
Industrial Serial Control Console
The SP232EEP-L fits an industrial control console requiring two RS-232 transmit channels and two receive channels from one interface IC. Its 2/2 full-duplex arrangement supports simultaneous command transmission and status reception, while its verified 120kbps rate covers standard UART baud rates through 115200 bps. The 4.5V to 5.5V supply range simplifies connection to 5V digital logic, and the -40°C to +85°C rating supports temperature-controlled equipment. The ±15kV HBM ESD rating adds connector-level robustness, although external surge protection may still be required for industrial transients.
おすすめ
Point-of-Sale Terminal Interface
The SP232EEP-L is suitable for point-of-sale equipment that exchanges commands, receipts, and peripheral status over RS-232. Two drivers and two receivers provide flexible channel allocation within one 16-pin PDIP package, while the 120kbps capability supports conventional serial peripherals operating at 9600 through 115200 bps. The device operates from 4.5V to 5.5V and includes ±15kV Human Body Model ESD protection for a connector that may be handled by operators. PCB layout should keep charge-pump loops compact and provide a controlled signal ground to the connector shell.
おすすめ
Barcode Reader and Peripheral Connectivity
The SP232EEP-L can connect barcode readers, scales, label printers, or other legacy serial peripherals to embedded control boards. Its dual-driver, dual-receiver organization permits one device to support more than one unidirectional RS-232 link, and its 120kbps rate is appropriate for common scanner and printer baud rates. The 5V supply range aligns with many embedded systems, while the -40°C to +85°C operating range broadens deployment options. Engineers should confirm logic levels, cable length, connector pin numbering, and driver slew behavior against the complete datasheet and application environment.
おすすめ
Legacy Computer Serial Adapter
The SP232EEP-L is appropriate for a legacy computer serial adapter intended to bridge modern UART logic to an RS-232 port. Its 120kbps maximum data rate supports legacy peripherals while remaining compatible with RS-232 and V.28 protocol expectations. The 2/2 full-duplex configuration allows independent transmit and receive channels, and the 16-pin PDIP package can simplify through-hole prototyping or repair. For installed equipment, use a short twisted-pair cable, maintain a common reference ground where permitted, and avoid presenting unverified RS-232 voltage and power specifications to users.
おすすめ
Test and Measurement Instrumentation
The SP232EEP-L can provide legacy RS-232 control and response channels in test and measurement instrumentation. The dual transmitter and dual receiver arrangement is useful where an instrument must issue commands and return data through separate serial links. Its verified 120kbps rate and ±15kV HBM ESD rating support laboratory equipment connected to service ports or peripheral modules, although bench cables can introduce significant ground offsets. Keep the transceiver ground reference close to the connector return, place protection away from sensitive logic, and verify the complete electrical limits before setting cable length or baud rate.
おすすめ
Embedded Serial Port Bridge
The SP232EEP-L is suitable for an embedded serial-port bridge that translates a microcontroller or processor UART into an RS-232 connection. The 4.5V to 5.5V operating range supports conventional 5V systems, and the 120kbps limit accommodates conventional UART traffic without implying support for higher-speed RS-232 designs. Two drivers and two receivers can connect more than one external serial endpoint. The design must include the manufacturer-specified external charge-pump capacitors and account for UART logic thresholds, cable capacitance, connector grounding, and any industrial surge requirements beyond the verified ±15kV HBM rating.

設計ノート
Place the external charge-pump capacitors at the locations shown in the manufacturer datasheet and connect each capacitor directly to its designated IC pin with a short, low-loop-area trace. Keep the capacitor return path on the same ground plane as the device ground without routing it through the protected connector ground. Long charge-pump traces can increase converter stress and radiated noise, so avoid substituting leaded capacitors or long routed connections.
Do not treat a family-level pin-compatibility statement as permission to interchange every ordering suffix. SP232EEP-L is verified as a 16-pin PDIP part; confirm the physical package, temperature range, channel configuration, shutdown or enable pins, ESD rating, and complete suffix of an alternative before ordering. MAX202IDR and SP232ECT-L are not same-footprint substitutes for a board built around the SP232EEP-L PDIP footprint.
RS-232 receivers can interpret ground offsets as data, particularly on long cables or when two powered systems share a connector. Use twisted-pair wiring, maintain the intended signal-reference connection, avoid routing RS-232 traces directly beside noisy switching nodes, and terminate or protect the connector according to the system’s EMC test requirements. The verified ±15kV HBM rating improves static robustness but does not guarantee immunity to industrial surge events.
The verified 120kbps maximum rate should be treated as the upper device limit, not an automatic guarantee for every cable, connector, or ground condition. At 115200 bps, include UART framing overhead, cable capacitance, driver loading, and receiver thresholds in the margin assessment. If the design must operate continuously at 120kbps, reproduce the datasheet’s recommended load and verify waveform timing with the final cable and connector.
