Description

MAX3488EESA is a single-channel, low-power RS-485/RS-422 transceiver from Maxim Integrated. It provides a DI input and RO output for a UART-style interface, with separate DE (driver enable) and RE (receiver enable) controls, enabling half-duplex RS-485 operation on the A/B bus. It supports high data rates (up to tens of Mbps) and operates from a 3.0–5.5 V supply. The part includes a fail-safe receiver that guarantees RO is high when the bus is idle, open, or shorted. It also offers robust ESD/bus protection on the A/B lines and low quiescent current for power-sensitive applications. Typical uses include industrial control, building automation, data acquisition, PLCs, and microcontroller RS-485 networks. Package: 8-pin SOIC (EESA denotes RoHS/industrial-temp version). Key pins: VCC, GND, A, B, DI, RO, DE, RE.

Equivalent

MAX3488EESA is a MAXIM RS-485/RS-422 transceiver. Equivalent cross-refs depend on features (isolated vs non-isolated, channels). Common alternatives: TI SN65HVD238/239 (RS‑485), Analog Devices ADM2483/ADM2482 (isolated RS‑485), Microchip MCP2551/MCP2561 (RS‑485 transceivers), NXP TJA1041/TJA1042. For an exact one‑to‑one, please share the datasheet or the required features.

Features

Key features of MAX3488EESA (RS-485/RS-422 transceiver):
- Half‑duplex, 2‑wire RS‑485/RS‑422 compatible transceiver
- 1/8 unit load on the bus for multipoint networks
- Single-supply operation with enable pins for both driver and receiver
- Fail-safe receiver output (defined logic level on open/shorted/idle bus)
- Low power/low quiescent current
- Robust ESD protection on bus pins
- Industrial temperature grade (E suffix indicates extended temp range)
- 8‑pin package available (e.g., SOIC or MSOP variants)
- RoHS-compliant packaging
Note: For exact supply voltage ranges, data rates, and package options, refer to the official datasheet.

Pinout

MAX3488EESA is an 8-pin single‑channel RS-485/RS-422 transceiver in an 8-pin package (SOIC/SSOP). It provides both a driver and a receiver for a differential bus.
Pins (typical):
- A, B: differential bus lines
- DI: data input to the driver
- RO: receiver data output
- DE: driver enable
- /RE (or RE): receiver enable (active low)
- Vcc: supply
- GND: ground
Operation: DE enables the driver to drive A/B; /RE enables the receiver to present RO; when DE is low and /RE is high, the device is high-impedance on the bus. Suitable for half‑duplex RS-485/RS-422 communication.

Manufacturer

- Manufacturer: Maxim Integrated Products, Inc. (now part of Analog Devices).
- What kind of company: A global semiconductor company that designs and manufactures analog and mixed-signal integrated circuits used in a wide range of electronics.

Application

MAX3488EESA is a high‑speed, low‑power RS‑485/RS‑422 transceiver (half‑duplex) for multi‑point networks. Common application areas include:
- Industrial automation and process control (PLCs, sensors, I/O networks)
- Building automation (HVAC, lighting, security, energy meters)
- Remote telemetry and data acquisition
- Instrumentation and test equipment using RS‑485 links
- Microcontroller/embedded system interfaces over twisted pair
- Harsh/extended‑temperature environments (industrial/automation use)
It supports robust differential signaling and is compatible with 3.3V or 5V MCU interfaces.

Package

An 8-pin SOIC (Small-Outline Integrated Circuit) package.
