MAX3488ESA+ 概要
An RS-485/RS-422 transceiver is an interface IC that converts logic-level digital signals into differential differential-pair signals for communication over longer cables or noisy industrial environments. The RS-485 standard is commonly associated with half-duplex multidrop buses, while RS-422 provides differential signaling and can support point-to-point links. The MAX3488 combines these physical-layer functions with integrated driver and receiver circuitry.
The principal verified feature is slew-rate limiting, which reduces the rate at which the driver output changes. This can help reduce unwanted reflections and electromagnetic interference on suitably terminated buses. The 10Mbps capability supports higher-speed links than basic 250kbps transceivers, while the low 3.3V supply is appropriate for modern embedded systems. The MAX3488 family also includes related devices, but the specific package and ordering suffix must be checked before substitution.
Typical uses include industrial control equipment, sensor networks, building automation, instrumentation, data acquisition, and embedded serial links where differential signaling is required. The MAX3488ESA+ is particularly relevant when a board needs a compact, integrated RS-485 or RS-422 physical-layer solution rather than discrete driver and receiver stages.
Designers should verify the complete pinout, supply requirements, driver and receiver enable behavior, bus termination, common-mode limits, and maximum cable length against the manufacturer datasheet before production. Do not infer unverified electrical limits or pin names from a distributor listing.

主な用途
MAX3488ESA+ の用途: 6 件s: Industrial RS-485 Control Bus, Building Automation Sensor Network, Data Acquisition and Instrumentation, Embedded Serial Communication, Industrial Sensor and Actuator Link, Short-Distance High-Speed Differential Link.
Industrial RS-485 Control Bus
The MAX3488ESA+ fits an industrial controller that must connect a digital processor to a differential RS-485 network. Its verified 3.3V supply aligns with modern embedded control logic, while the one-driver/one-receiver arrangement supports half-duplex communication when the bus direction is controlled. The verified 10Mbps capability is useful for short, well-laid-out links, and slew-rate limiting helps control edge-related EMI. The design still needs correct termination, biasing, grounding, protection, and conductor topology. Use the manufacturer datasheet to confirm enable behavior and electrical limits before selecting the final resistor network.
おすすめ
Building Automation Sensor Network
The MAX3488ESA+ can serve as the differential interface in a building-automation controller or sensor gateway that must communicate over a longer RS-485 wiring run. A 3.3V transceiver is useful when the controller uses a low-voltage embedded supply, and the verified slew-rate limitation can reduce unwanted high-frequency edge content when the bus is properly terminated. The application should place the transceiver near the connector, protect the external lines against surges, and maintain a controlled ground relationship. Maximum reliable distance is not established by the supplied data and depends on baud rate, cable, topology, and transceiver loading.
おすすめ
Data Acquisition and Instrumentation
The MAX3488ESA+ is suitable for an instrument that exchanges commands and measurements with a remote data-acquisition module over an RS-422 or RS-485 differential link. The verified one-driver/one-receiver configuration provides the basic physical-layer functions without requiring separate discrete driver and receiver packages. The 10Mbps rating can support short-distance high-rate links, while the 3.3V supply simplifies integration with low-voltage analog and digital circuitry. For reliable measurement results, keep the differential pair appropriately routed, provide the required bus network components, and validate common-mode and ground conditions against the complete datasheet.
おすすめ
Embedded Serial Communication
The MAX3488ESA+ can connect a 3.3V embedded controller to an external differential serial device when the board lacks an RS-485 or RS-422 transceiver. Its 8-SOIC package supports compact surface-mount layouts, and its driver/receiver pair supports bidirectional communication with the correct direction-control arrangement. The verified 10Mbps capability offers flexibility for short high-speed links, but the firmware must manage bus turnaround and avoid multiple drivers. PCB layout should minimize the distance between the transceiver and connector while following the manufacturer’s differential-pair and grounding recommendations.
おすすめ
Industrial Sensor and Actuator Link
The MAX3488ESA+ is applicable to distributed sensor and actuator nodes where a controller communicates with remote I/O over a differential bus. Its low-voltage 3.3V operation can simplify system partitioning, and the verified true RS-485/RS-422 classification supports use in noise-prone industrial environments when the external network is correctly engineered. Slew-rate limiting helps manage reflections on terminated cables, but it does not substitute for proper topology, surge protection, or grounding. Confirm the exact input thresholds and output levels in the datasheet before connecting to a particular microcontroller family.
おすすめ
Short-Distance High-Speed Differential Link
The MAX3488ESA+ can be selected for a short, controlled differential link requiring data rates up to the verified 10Mbps capability. Its slew-rate-limited driver is relevant when the design must reduce uncontrolled edge energy compared with an unrestricted high-speed driver, while the integrated receiver avoids a separate receiver package. The practical limit is determined by the complete channel: cable type and length, connector, termination, grounding, protection components, and node loading. Do not select a high-speed link solely from the headline Mbps rating; review timing and signal-integrity constraints in the manufacturer documentation.

主な差別化要因
- Verified 10Mbps data-rate capability （vs MAX3488ECSA+)

- 3.3V low-power interface positioning （vs MAX3441EASA)
設計ノート
Treat the RS-485 or RS-422 pair as a controlled-impedance differential connection rather than two unrelated traces. Keep the pair adjacent, minimize stubs and branch lengths, and place termination components near the appropriate physical ends of the bus. The verified MAX3488 data rate is up to 10Mbps, so edge-rate and propagation-delay behavior must be checked against the actual cable and transceiver load.
Provide a clean 3.3V supply to the MAX3488ESA+ and verify the exact supply-current, decoupling, and logic-level requirements from the manufacturer datasheet. Place the transceiver’s supply bypass capacitor close to its supply and ground pins. Because the verified snippets do not state the complete operating-voltage range, do not design production power sequencing or 5V interfacing from the nominal 3.3V label alone.
Place the transceiver near the external connector so the differential bus leaves the board over a short, controlled path. Keep the logic-side traces away from the bus connector and its protection components, and maintain the ground reference recommended by the manufacturer. Confirm the 8-SOIC footprint and pinout from the official datasheet before layout release; the supplied data confirms the package but does not provide pin names.
Do not approve MAX3488ECSA+, MAX3488E, MAX3442EASA+T, or MAX3441EASA as a substitute solely because they are related Maxim parts or appear in search results. Check exact pin functions, driver and receiver thresholds, common-mode range, supply limits, ESD rating, temperature grade, and package drawing. A true drop-in decision requires complete datasheet equivalence and, preferably, validation on the finished board.
コンプライアンス情報
The supplied verified snippets do not include current RoHS, REACH, lead-free, halogen-free, or conflict-minerals declarations for the exact MAX3488ESA+ ordering code. AEC-Q100 status is not established; not_applicable is recorded for this non-automotive-specific interface context, but it does not assert regulatory certification.
