Descripción general

Description

MAX3232EWE is a dual RS-232 transceiver from Maxim Integrated (now Analog Devices). It provides two RS-232 drivers (TTL/CMOS to RS-232) and two receivers (RS-232 to TTL/CMOS), enabling microcontrollers to talk to RS-232 devices (PC COM ports, modems, etc.) from a single 3.3–5.5 V supply. It uses an internal charge-pump to generate RS-232 voltage levels, so no ±12 V supply is needed. Typical data rates are in the hundreds of kbps (often up to about 250 kbps). The device draws low quiescent current and requires only four external charge-pump capacitors plus standard bypassing. The EWE suffix indicates a RoHS-compliant, lead-free package (usually in a 16-pin package). Common applications include microcontroller-to-PC interfaces, GPS receivers, modems, and other embedded serial links where a compact, low-power RS-232 transceiver is needed. In short: a convenient, dual RS-232 interface bridge for modern 3.3/5 V MCUs.

Package

MAX3232EWE comes in a 16‑pin TSSOP (Thin Shrink Small Outline) package and is RoHS-compliant (lead-free).

Pinout

- Pin count: 16 pins (dual RS-232 transceiver in a 16-pin package).
- Function: Dual RS-232 driver/receiver transceiver; converts TTL/CMOS logic levels to RS-232 voltage levels and RS-232 levels back to TTL/CMOS, using an internal charge-pump to generate the necessary RS-232 voltages.

Manufacturer

- Manufacturer: Maxim Integrated (now part of Analog Devices, Inc., ADI).
- What kind of company: A semiconductor company that designs and manufactures analog and mixed-signal integrated circuits.

Application

Typical applications of MAX3232EWE include:
- RS-232 serial interfaces for microcontrollers/embedded systems
- Modems, network equipment, routers, and gateways
- Serial peripherals (printers, scanners, POS terminals, data loggers)
- Portable or battery-powered devices needing RS-232 from a 3V–5.5V supply
- Industrial instrumentation and data acquisition systems requiring reliable TTL-to-RS-232 level conversion

Equivalent

Equivalent products: ST SP3232E / SP3232; Analog Devices ADM232 / ADM232A; Exar XR-232 (2-channel RS-232 transceiver). Check voltage range, capacitor requirements, and pinout for compatibility.
