Overview

Description

MAX202EEWE is a dual RS-232 transceiver from Maxim (a variant of the MAX202). It provides two RS-232 drivers and two receivers to connect a microcontroller UART to a PC/modem serial port. It converts TTL/CMOS logic levels to RS-232 voltages and RS-232 inputs back to TTL logic. The device uses an on‑chip charge pump that, with four external capacitors, generates the RS-232 ± voltages from a single supply. It typically operates from 3 to 5.5 V and supports data rates up to several hundred kilobits per second. Pins include VCC, GND, two TIN inputs, two ROUT outputs, two RIN inputs, and the four charge‑pump capacitors (C1+, C1−, C2+, C2−). The EEWE suffix denotes a specific package/temperature variant; check the datasheet for exact limits.

Features

Concise features of MAX202EEWE (RS-232 transceiver):
- Quad RS-232 transceiver: two drivers and two receivers
- Single-supply operation with on-chip charge pump to generate RS-232 levels
- External capacitor requirements for the charge pump (typical small values)
- TTL/CMOS compatible inputs; RS-232 level outputs
- RS-232 output swing suitable for standard RS-232 signaling (±voltage range)
- Moderate to high data-rate capability for serial communication
- 8-pin package; EEWE suffix indicates extended temperature grade and package variant
- Low power with possible low-power/power-down options
- Protective features: ESD/short-circuit protection for rugged use
Note: exact supply voltage range, capacitor values, and data rate depend on the specific sub-variant; the EEWE version emphasizes extended temperature operation in an 8-pin package.

Package

MAX202EEWE comes in an 8-pin SOIC (Small Outline Integrated Circuit) package.

Pinout

Pin count: 8 pins (8-pin package such as SOIC-8/DIP-8).
Function: Dual RS-232 transceiver (two drivers and two receivers) that converts TTL/CMOS logic levels to RS-232 levels and RS-232 levels back to TTL/CMOS; uses a charge-pump to generate the required RS-232 voltages from a single supply (typ. +5V).

Manufacturer

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