Visão Geral

Description

MAX3232ESE+T is a Maxim/Analog Devices RS-232 transceiver pair with two drivers and two receivers. It lets a microcontroller or logic device (TTL/CMOS) talk to RS-232 serial ports.
Key points:
- Single-supply operation: 3.0 V to 5.5 V
- On-chip charge pump generates RS-232 voltage swings (no negative rail needed)
- Requires four external charge-pump capacitors (values per datasheet, typically in the 0.1–1 µF range)
- Data rate up to about 250 kbps
- E suffix indicates extended temperature range (-40°C to +85°C); +T indicates Tape & Reel packaging for automated assembly
Common use: connecting MCUs/systems to RS-232 interfaces in embedded and communication devices.

Equivalent

Possible equivalents (2 Tx / 2 Rx RS-232 transceivers) include:
- STMicroelectronics ST3232
- Analog Devices ADM232/ADM3232
- Texas Instruments SP3232E
- Microchip MCP2321/MCP2322
Note: ensure voltage (5V or 3.3V) and pinout/package compatibility; MAX3232ESE+T suffix is just packaging (Tape‑and‑Reel).

Features

Here are the key features of MAX3232ESE+T (dual RS-232 transceiver, extended temp, Tape & Reel):
- Dual EIA/TIA-232 drivers and receivers (2 TX/2 RX)
- Single-supply operation: 3.0 V to 5.5 V
- RS-232 output levels generated from supply via internal charge pump
- External charge-pump capacitors: four capacitors (0.1 µF to 1 µF)
- Data rate up to ~250 kbps
- Extended temperature version: -40°C to +85°C
- 16-pin package options; Tape & Reel packaging (+T)
- Pin-compatible with MAX232 family
Optional: RS-232 outputs typically ±6 V to ±7 V, TTL/CMOS on receiver outputs.

Pinout

- Pin count: 16 pins (DIP-16/SO-16 variants; package may vary with +T option).
- Function: Dual RS-232 transceiver (two drivers and two receivers). Converts TTL/CMOS UART signals to RS-232 voltage levels and back; uses an external charge-pump capacitor network to generate RS-232 voltages. Used to connect microcontrollers to RS-232 serial ports.

Manufacturer

- Manufacturer: Maxim Integrated, now part of Analog Devices, Inc. (ADI).
- About the company: A global American semiconductor company specializing in designing and manufacturing analog and mixed-signal integrated circuits for a wide range of electronic applications.

Application

MAX3232ESE+T is a dual RS-232 transceiver (TTL/CMOS to RS-232). Typical applications:
- Embedded systems and microcontroller UART to RS-232 interfaces
- PC serial ports, modems, routers, printers, and other serial peripherals
- Industrial automation, PLCs, data loggers, and test/measurement equipment
- Point-of-sale terminals and peripherals
- USB-to-serial adapters and console ports
- Any low-power, single-supply (3V–5.5V) RS-232 link, including extended temperature environments (ESE+T)

Package

MAX3232ESE+T is in an 8-pin Small Outline Package (SO-8 / SOP-8); “+T” indicates Tape-and-Reel packaging.
