概述

Description

MAX3082ECSA+T is a dual RS-232 transceiver from Maxim (now Analog Devices). It provides two RS-232 drivers and two receivers, enabling a direct TTL/CMOS to RS-232 bridge for microcontrollers and RS-232 devices. It runs from a single supply (typical 3.3 V or 5 V) and uses an on‑chip charge pump to generate RS‑232 level swings, so no external level shifter is needed. The ECSA+T suffix indicates the package/ordering option (CSA package) with Tape & Reel shipping. Common applications include microcontroller serial interfaces to PCs/modems, industrial equipment, data loggers, and GPS modules. Key takeaways: small footprint, low external component count, easy integration for standard RS-232 communications.

Features

Here are the typical features of the MAX3082ECSA+T (RS-232 transceiver, quad channel):
- 2 transmitters and 2 receivers (2 Tx / 2 Rx)
- Single-supply operation: 3.0 V to 5.5 V
- Internal charge-pump RS-232 level shifters (no external RS-232 supply needed)
- True RS-232 voltage levels with TTL/CMOS-compatible inputs
- Data rate capability up to about 1 Mbps (typical)
- ESD protection on RS-232 lines (robust to ESD events)
- Extended temperature option: suitable for -40°C to +125°C
- RoHS/compliant packaging; CSA package with Tape & Reel (+T option)
Note: exact electrical specs (currents, voltage levels, max data rate) are best confirmed in the latest datasheet for your specific suffix.

Package

An 8-pin SOIC package (SOIC-8), Tape‑and‑Reel (the +T denotes T&R).

Pinout

Pin count: 8 pins (S0IC-8). Function: One-channel RS-232 transceiver (driver and receiver) with TTL/CMOS interface; converts logic levels to RS-232 levels and back, using an internal charge-pump to generate RS-232 voltages from a single supply. Packaging suffix indicates extended temperature (E), CSA package, and tape-and-reel (T).

Manufacturer

- Manufacturer: Maxim Integrated Products (the MAX3082ECSA+T is a Maxim part). Maxim Integrated is now part of Analog Devices.
- What kind of company: A semiconductor company that designs analog and mixed-signal integrated circuits (now under Analog Devices).

Application

MAX3082ECSA+T is a low‑power RS-485/RS-422 transceiver. Typical application areas include:
- Industrial automation and process control (multi‑drop RS‑485)
- Building automation (HVAC, lighting)
- Remote monitoring and telemetry
- PLCs, DCS, instrumentation
- Sensor networks and data acquisition
These links benefit from robustness and low power in harsh environments.

Equivalent

Equivalent parts (2-channel RS-232 transceivers) to MAX3082ECSA+T include:
- Maxim: MAX3221 / MAX3223
- TI: UCC2322 / UCC2323
- ST: SP3222 / SP3232
- Analog Devices: ADM232A / ADM3232
Note: verify supply voltage range, data rate (≈250 kbps), I/O timing, and pinout/power-polarity for exact cross-reference.
