MAX13487EESA+ 500kbps RS-485/RS-422 Transceiver
MPN: MAX13487EESA+ ✓ Hoạt độngMAX13487EESA+ Tóm tắt
An RS-485/RS-422 transceiver is an interface IC that converts between single-ended logic signals used by a controller or MCU and differential signals carried across a noisy, long-distance bus. It belongs to the communications-interface hierarchy: interface IC → differential transceiver → RS-485/RS-422 interface. One transceiver supports bidirectional half-duplex communication, so the same pair of bus conductors carries traffic in either direction, but only one side transmits at a time.
The MAX13487EESA+ provides 500 kbps operation, a +5 V supply, automatic direction control, hot-swap capability, and ±15 kV ESD protection according to the manufacturer datasheet. AutoDirection control is particularly useful when the system has no convenient GPIO for asserting driver enable. Hot-swap capability helps prevent false bus transitions during startup and live insertion, while ESD protection improves robustness against electrostatic discharge encountered in industrial environments.
The MAX13487EESA+ is suited to RS-485-compatible multidrop networks, RS-422-compatible point-to-point links, industrial control systems, instrumentation, building automation, and communications equipment where a compact 500 kbps half-duplex transceiver is required. The device is available in an 8-SOIC package, making it appropriate for conventional PCB assembly and replacement workflows.
When designing around the MAX13487EESA+, verify the complete datasheet pinout, termination requirements, bus topology, grounding, and supply decoupling before production release. The automatic direction-control architecture should be reviewed for compatibility with the system’s bus timing and fault-recovery expectations. This page combines verified manufacturer and distributor information with package, application, and replacement-oriented engineering guidance.

Ứng dụng tiêu biểu
MAX13487EESA+ phù hợp cho 6 Áp dụngs: Industrial RS-485 Control Links, Building Automation Networks, Instrumentation and Sensor Networks, Data Acquisition Terminals, Remote Motor and Equipment Control, Communications and Gateway Equipment.
Industrial RS-485 Control Links
The MAX13487EESA+ fits industrial control and instrumentation links that need a compact, half-duplex differential transceiver at up to 500 kbps. Its one-driver/one-receiver arrangement supports bidirectional bus communication, while AutoDirection control can reduce external direction-control logic. The 8-SOIC package is convenient for conventional surface-mount assembly. ±15 kV ESD protection and hot-swap capability are valuable when the transceiver is connected to equipment that may be powered on or inserted while the bus is active. Before release, verify termination, biasing, common-mode limits, and grounding against the complete manufacturer datasheet.
Được đề xuất
Building Automation Networks
The MAX13487EESA+ can serve as the physical-layer interface in building-automation equipment communicating over RS-485-compatible differential buses. The 500 kbps rate is suitable for many supervisory-control links, while half-duplex operation allows shared wiring and automatic direction control simplifies firmware behavior. Hot-swap capability helps limit false bus transitions during equipment startup or maintenance. The design must still account for cable length, topology, termination, common-mode voltage, and isolation requirements; the device is not automatically an isolated interface.
Được đề xuất
Instrumentation and Sensor Networks
The MAX13487EESA+ is suitable for multidrop RS-485-compatible measurement systems where a remote instrument must communicate over a shared differential bus. Its 500 kbps rate supports moderate-speed sensor and control traffic, and automatic direction control avoids a dedicated GPIO on many systems. The ±15 kV ESD rating helps protect the interface in industrial environments, but cable routing and grounding remain critical. Validate the bus topology, termination resistor placement, fail-safe behavior, and maximum node count against the system specification and manufacturer datasheet.
Được đề xuất
Data Acquisition Terminals
The MAX13487EESA+ can provide the RS-485/RS-422-compatible physical interface in compact data-acquisition terminals. A single half-duplex transceiver handles both transmit and receive paths, while 500 kbps bandwidth is sufficient for many serialized measurement channels. AutoDirection control is useful when the terminal software must communicate in both directions without managing a dedicated driver-enable line. Designers should still budget for connector protection, cable termination, surge-current strategy, and grounding because the transceiver’s ±15 kV ESD protection does not replace external protection networks.
Được đề xuất
Remote Motor and Equipment Control
The MAX13487EESA+ can interface a controller to remote equipment over a half-duplex RS-485-compatible command and status bus. The 500 kbps rate provides enough bandwidth for command polling, status reporting, and configuration traffic in many embedded systems. Automatic direction control simplifies communication between the controller and remote node, while hot-swap capability reduces startup disturbance. For motor or high-energy equipment, place the transceiver in the appropriate protected communications path and verify isolation, surge protection, and fault behavior separately.
Được đề xuất
Communications and Gateway Equipment
The MAX13487EESA+ is useful in gateways and communication interfaces that must bridge a local controller to an RS-485/RS-422-compatible field bus. Half-duplex operation, AutoDirection control, and hot-swap capability make it practical for compact equipment with limited control-pin resources. The 8-SOIC package supports standard PCB assembly, and the 500 kbps rate is appropriate for supervisory or control traffic rather than high-speed storage links. Confirm logic thresholds, bus loading, termination, and isolation strategy against the complete system requirements.

Ghi chú thiết kế
Place the transceiver close to the bus connector and route the differential pair as a controlled, impedance-consistent pair. Keep the ground reference continuous beneath the interface and return current path. Separate the RS-485/RS-422 traces from switching-converter and high-current power paths to reduce differential noise pickup. Verify connector pin mapping against the MAX13487E/MAX13488E datasheet rather than relying only on the package name.
Apply termination and fail-safe biasing according to the physical bus topology rather than adding resistors indiscriminately. For a point-to-point link, termination may be placed at the receiver ends; for multidrop networks, termination placement depends on the complete wiring. Check cable length, stub lengths, common-mode range, and the maximum capacitive loading against the manufacturer’s electrical characteristics before signing off the layout.
Do not assume that every 8-pin RS-485 IC is pin-compatible. The MAX13487EESA+ uses the MAX13487E/MAX13488E family pinout and AutoDirection architecture, while replacement candidates may use different receiver-enable or driver-enable conventions. Confirm every pin, supply tolerance, bus threshold, timing parameter, and package dimension. Also remember that ±15 kV ESD protection does not eliminate the need for appropriate external surge and lightning protection.
