概要

Description

MAX3237EIDBR is a Maxim/Analog Devices RS-232 transceiver. It provides two drivers and two receivers to bridge a microcontroller’s TTL/CMOS UART to RS-232 serial lines.
Key points:
- Single-supply operation from 3.0 to 5.5 V
- Uses external charge-pump capacitors to generate RS-232 voltage swings
- Two transmit channels and two receive channels
- Suitable for UART speeds (high enough for typical serial links)
- Protects against ESD and includes safety features (e.g., undervoltage lockout)
- Package: 8-pin, RoHS-compliant, industrial temperature range (suffix E and BR indicate industrial temp and tape‑and‑reel packaging)
Typical use: connect MCU TX/RX to the TTL side and RS-232 DB9/UART device to the RS-232 side. It’s ideal for PCs, modems, and embedded systems requiring TTL-to-RS-232 conversion.

Features

Here are the key features of MAX3237EIDBR:
- 4 RS-232 drivers and 4 RS-232 receivers (8 data lines)
- Single-supply operation: 3.0 V to 5.5 V
- On-chip charge pump to generate RS-232 levels; requires four external capacitors (typical 0.1 µF)
- TTL/CMOS input thresholds compatible with VCC levels
- RS-232 output levels typically ±6 V
- Low quiescent current with available power-down mode
- Industrial temperature range: -40°C to +85°C
- 16-pin, RoHS-compliant, lead-free package (EIDBR)
- ESD protection on RS-232 and TTL/CMOS pins
- Ideal for multi-port serial interfaces in embedded systems and PC peripherals

Package

An 8-pin small-outline package (SOIC), RoHS-compliant IDB variant.

Pinout

8 pins. It is a dual RS-232 transceiver (two drivers and two receivers) that converts TTL/CMOS UART signals to RS-232 levels and RS-232 signals back to TTL, using an internal/external charge-pump to generate the needed voltages.

Manufacturer

- Manufacturer: Maxim Integrated (now part of Analog Devices, Inc.).
- Company type: a fabless semiconductor company that designs and markets analog and mixed-signal integrated circuits (e.g., RS-232 transceivers).

Application

MAX3237EIDBR is a single-channel RS-232 transceiver (TTL/CMOS to RS-232) with a charge pump for 3.3V operation. Typical applications:
- Microcontroller/embedded systems to RS-232 hosts (PCs, modems, POS terminals)
- Industrial control and automation
- Data acquisition and instrumentation
- Telecom/networking equipment
- Any device requiring a simple RS-232 interface
