Overview

Description

MAX3243EAI+T is a low‑power RS‑232 transceiver (from Maxim Integrated, now Analog Devices) that provides both RS‑232 drivers and receivers and uses an on‑chip charge pump to generate RS‑232 voltage levels from a single supply. External charge‑pump capacitors (typically 0.1 µF) are required. It translates TTL/CMOS logic to RS‑232 voltages and back, enabling microcontrollers to communicate with PCs, modems, and other RS‑232 peripherals. The MAX3243E is a multi‑channel variant (exact channel count depends on the package/variant). It supports 3.0–5.5V operation, low quiescent current, true RS‑232 voltage swings, and three‑state outputs for bus sharing across devices, with a broad commercial/industrial temperature range. The +T suffix denotes Tape & Reel packaging; AI indicates a specific package/grade. For exact features (channel count, data rate, package), consult the datasheet.

Features

Here are key features of MAX3243EAI+T (quad RS-232 transceiver):
- Quad RS-232 transceiver: 4 drivers and 4 receivers
- Wide supply range: 3.0V to 5.5V (suitable for 3.3V MCUs)
- On-chip charge-pump: generates RS-232 levels from a single supply
- External capacitors: four 0.1 µF capacitors required (typical)
- Data rate: up to about 250 kbps
- Enable control: separate Driver Enable and Receiver Enable for power-down
- Industrial temp variant: E grade (-40°C to +85°C)
- ESD/surge protection on RS-232 lines; robust I/O protection
- Low quiescent current; RoHS-compliant; available in Tape & Reel (+T) packaging
Optional: common package types include small TSSOP/SOIC footprints.

Package

MAX3243EAI+T is a 16-pin surface-mount SOIC package (16-lead), provided in Tape‑and‑Reel packaging.

Pinout

- Pin count: 16 pins (SSOP/TSSOP-16)
- Function: Dual RS-232 transceiver (two drivers and two receivers) with on-chip charge pump. Converts TTL/CMOS logic levels to RS-232 levels and RS-232 back to TTL/CMOS. Operates from 3.0–5.5 V (typical 3.3 V in many applications).

Manufacturer

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

Application

MAX3243EAI+T is a 3.3V RS-232 transceiver (3 Tx, 3 Rx) for converting UART/TTL to RS-232 levels. Applications: 3.3V embedded systems requiring RS-232, such as PCs/serial ports, modems, printers, POS terminals, industrial controllers, data loggers, GPS/GSM modules, telecom/network equipment, and other serial communication interfaces.

Equivalent

Quad RS-232 transceivers pin-compatible with MAX3243EAI+T include:
- Analog Devices ADM3243/ADM3243A
- Renesas ISL3243 (Intersil)
- Exar SP3243 (SP3243E)
Note: verify pinout, voltage, and suffix/temperature rating for exact packaging.
