概要

Description

MAX3088EESA is a Maxim (now Analog Devices) RS-485/RS-422 transceiver. It provides a UART-to-differential-bus interface, enabling reliable multi-point serial communication in industrial networks. The device typically integrates a line driver and a receiver, with three-state enable controls (DE/RE) for bus sharing and failure-safe receiver operation.
Key features (typical):
- Single-supply operation (commonly 3.3–5 V)
- Differential RS-485/RS-422 signaling
- Fail-safe receiver and enable controls
- Low power consumption and bus-pin ESD protection
- Suitable for long-distance, noisy environments and multi-drop networks
The EESA suffix denotes a specific variant (industrial/extended temperature, lead-free package—check the datasheet for exact temperature range and packaging).
Common applications:
- Industrial automation and PLCs
- Building automation and data acquisition
- Instrumentation and remote sensing
For exact electrical specs (data rate, voltage levels, pinout, and package), consult the MAX3088EESA datasheet.

Features

Here are the typical features of the MAX3088EESA (RS-485/RS-422 transceiver):
- High-speed, low-power RS-485/RS-422 two-wire transceiver (half-duplex)
- 1/8 unit load on the bus for multi-node networks
- Fail-safe receiver: guarantees a logic-high output when the bus is idle/open
- Wide receiver common-mode range with robust bus protection
- 3.3V to 5V supply operation; TTL/CMOS-compatible inputs
- DE/RE control for direction and receiver enable
- Extended temperature/industrial grade (EESA suffix indicates wide temp range, RoHS)
- 8-pin package (e.g., SOIC), suitable for compact designs
- Built-in protection features on bus pins; ESD/short-circuit robustness
- Suitable for harsh environments (temperature range typically -40°C to +125°C)
Note: For exact electrical specs (data rate, exact protection levels, and pinout), please consult the official MAX3088EESA datasheet.

Package

MAX3088EESA is in an 8-pin SOIC (Small Outline) package.

Pinout

Pin count: 8 pins (8-pin package, e.g., SOIC-8).
Function: MAX3088EESA is a single-channel RS-485/RS-422 transceiver (half‑duplex). It provides a driver and receiver: A/B differential bus pins, DI input, RO output, and control pins DE (driver enable) and /RE (receiver enable), plus Vcc and GND.

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI). The MAX3088EESA was originally from Maxim Integrated, and is now part of Analog Devices after their acquisition of Maxim.
About the company: Analog Devices is a multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits for communications, instrumentation, automotive, and industrial markets.

Application

MAX3088EESA is a low-power RS-485/RS-422 differential driver/receiver. Ideal for rugged, long-distance serial links. Typical applications: industrial automation and process control networks (PLC remote I/O, motor control), building automation and HVAC systems, data acquisition and instrumentation over twisted-pair, point-to-point and multi-point RS-485 networks, environmental sensing systems, and embedded microcontroller interfaces requiring robust differential signaling.

Equivalent

Equivalent RS-232 transceivers from other vendors include:
- TI MAX3232 (and MAX322x family)
- Analog Devices ADM232 / ADM232A
- STMicroelectronics SP3232 / ST232
- Exar/SP3232 (Renesas/MaxLinear variants)
These offer similar 3V–5V operation, 2-driver/2-receiver configurations, and comparable data rates. For a pin-for-pin cross-reference, consult the respective datasheets.
