MAX3097EESE+ Visão geral
A line receiver is an interface circuit that converts low-amplitude differential signals into a digital logic-level output. RS-422 and RS-485 are balanced serial-interface standards used to transmit data reliably over cables and through electrically noisy environments. The MAX3097EESE+ belongs to the receiver and interface-IC hierarchy, combining differential signaling, fault indication, and transient protection in one device.
Key features include three high-speed receivers, support for both RS-422 and RS-485 signaling, ±15 kV ESD protection, and operation up to 32 Mbps. The fault-detection circuitry indicates when a receiver input is not in a valid state, allowing system software or hardware monitoring logic to identify wiring faults, idle conditions, or abnormal bus states. The 16-pin NSOIC package supports conventional surface-mount PCB assembly.
The MAX3097E family is intended for industrial data links, factory equipment, communications interfaces, and other systems that use balanced differential signaling. Its three-channel architecture reduces component count when several receiver channels are required on one board. The ±15 kV ESD rating is particularly relevant to externally connected communication lines, where static discharge and cable-borne transients can damage interface circuitry.
Designers should verify the receiver’s fault-status logic, supply sequencing, input termination, and cable configuration against the manufacturer datasheet before production use. Differential receiver inputs should be routed as a matched pair, with appropriate grounding and protection implemented according to the system’s cable environment. The receiver is not a transmitter, so a separate RS-485 driver is required when a design needs bidirectional bus communication.
This product page consolidates verified manufacturer and distributor information, pricing references, package details, and application guidance for engineers evaluating the MAX3097EESE+. It is intended as a technical buying and design reference rather than a substitute for the complete manufacturer datasheet.

Aplicações típicas
MAX3097EESE+ é adequado para 6 aplicaçãos: Industrial RS-485 Communication Interfaces, Factory Automation Data Links, RS-422 Point-to-Point Communications, Telemetry and Remote Monitoring Equipment, Communication Circuit Cards, External Cable-Connected Control Systems.
Industrial RS-485 Communication Interfaces
The MAX3097EESE+ fits industrial equipment that needs several balanced receive channels on one board. Its three RS-422/RS-485 receivers reduce package count, while the 32 Mbps capability supports high-speed data transfer. The ±15 kV ESD protection is useful when the receiver channels connect to external equipment or long cables. Designers should use differential routing, controlled grounding, and validated surge protection around the communication interface.
Recomendado
Factory Automation Data Links
Factory automation systems commonly distribute machine data over balanced RS-485 networks. The MAX3097EESE+ provides three receive channels, 32 Mbps operation, and fault-status outputs that can help a controller monitor invalid bus states. It is appropriate for equipment interfaces where diagnostic information is useful, provided the cable topology, termination, and grounding are designed according to the communications standard.
Recomendado
RS-422 Point-to-Point Communications
The device can serve as the receiving element in RS-422 point-to-point links requiring multiple differential channels. Its three-receiver architecture is useful for control, status, or supervisory signals, while the 32 Mbps specification supports faster signaling than many legacy industrial interfaces. The design must confirm input thresholds, timing, termination, and fault behavior against the complete manufacturer datasheet.
Recomendado
Telemetry and Remote Monitoring Equipment
Telemetry systems benefit from the MAX3097EESE+ when several external communication lines must be monitored. The active push-pull fault outputs provide a way to report invalid receiver states to supervisory logic, and the ESD protection helps withstand static discharge at exposed interfaces. In battery- or field-powered equipment, engineers should still verify supply-current and power-budget requirements from the manufacturer documentation.
Recomendado
Communication Circuit Cards
The 16-pin NSOIC package is well suited to compact communication interface boards that need standardized surface-mount assembly. Three receive channels can support separate command, telemetry, or status lines, while fault indicators allow health monitoring without relying only on decoded data validity. Board layout should preserve differential-pair geometry and provide adequate return-path continuity through the interface section.
Recomendado
External Cable-Connected Control Systems
The MAX3097EESE+ is a practical candidate for control systems whose cable-connected inputs can encounter electrostatic discharge. Its ±15 kV ESD rating provides a defined input-protection target, and the operating range of -40 C to +85 C supports many industrial environments. The rating should be treated as a component-level specification, not a guarantee of immunity for the entire finished product.

Notas de projeto
Route each differential receiver input as a matched pair and maintain continuous ground/reference paths beneath the pair. Avoid adding long stubs, test pads, or unrelated high-current traces adjacent to the communication nets. The MAX3097EESE+ supports up to 32 Mbps according to the verified data, so edge-rate harmonics can be significant even when the cable appears electrically short.
Do not treat the MAX3097EESE+ as an RS-485 transmitter. It contains three receivers and fault-detection outputs, so a bidirectional link still needs a separate driver. Confirm the receiver’s valid-idle and fault-status behavior in the manufacturer datasheet before using those outputs for safety-critical monitoring, since the supplied data does not provide the individual logic thresholds or pin assignments.
Place ESD-protection and interface components close to the external connector, with the protected trace arranged so surge current has a short path to the board ground or protection network. Keep the receiver’s supply decoupling close to its supply pins and separate external cable routing from sensitive digital circuitry. These practices help preserve the stated ±15 kV component ESD capability without assuming it guarantees complete system immunity.
Informações de conformidade
The supplied verified data does not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. Compliance fields are therefore left unknown rather than inferred.
