概述

Description

The MAX202ESE is a dual RS-232 transceiver from Maxim Integrated (now Analog Devices) that provides two drivers and two receivers to connect TTL/CMOS logic to RS-232 serial ports. It uses a switched-capacitor charge pump to generate the required RS-232 voltage swings from a single supply.
Key points:
- Supply: 3.0 V to 5.5 V
- External capacitors: requires charge-pump caps (typically 0.1 µF)
- Outputs: RS-232 level swings; inputs are TTL/CMOS compatible
- Features: bidirectional two-channel operation, low power, ESD protection on I/O
- Applications: microcontroller to PC/serial peripherals, data loggers, embedded serial links
Usage note: ideal for low-pin-count MCU interfacing where a separate RS-232 driver/receiver is needed without a high-voltage supply.

Package

The MAX202ESE comes in a 16-pin Small Outline IC (SOIC-16) package.

Pinout

- Pin count: 8 pins (SOIC/8-pin package).
- Function: Dual RS-232 transceiver (two drivers and two receivers) that converts TTL/CMOS logic levels to RS-232 levels and vice versa, using an internal charge-pump to generate the RS-232 voltages from a single-supply.

Manufacturer

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

Application

MAX202ESE is a low-power, dual RS-232 transceiver with built-in charge pump. Applications: embedded systems and microcontrollers interfacing to RS-232 devices (PC COM ports, modems, printers), data acquisition and instrumentation, telecom and industrial equipment, POS terminals, and any serial communication link.

Equivalent

Equivalent parts (2-channel RS-232 transceivers, 3.0–5.5V):
- Analog Devices ADM202/ADM232
- STMicroelectronics SP3232E (SP3232 family)
- Maxim Integrated MAX3221/MAX3222 (and related MAX232-family devices)
Note: verify pinout, package, and voltage/temperature specs for exact drop-in compatibility.
