概要

Description

MAX202EEWE is a Maxim/Analog Devices dual RS-232 transceiver. It provides two drivers (TTL/CMOS to RS-232) and two receivers (RS-232 to TTL/CMOS) in a single device, enabling a microcontroller or FPGA to interface with RS-232 serial ports.
Key points:
- On-chip charge pump generates RS-232 voltage swings from a single supply (no external high-voltage supply needed).
- Typical supply range is around 3.0–5.5 V; external capacitors are required for the charge pump (per datasheet).
- Suitable for low-pin-count, low-power serial interfaces in embedded systems, PCs, modems, and industrial controllers.
- EEWE suffix indicates a specific package/temperature variant; check the exact datasheet for pinout, capacitor values, and electrical specs for your part.
For precise electrical characteristics, pinout, and capacitor values, refer to the MAX202EEWE datasheet.

Features

Key features of MAX202EEWE (dual RS-232 transceiver):
- 2 transmitters and 2 receivers (dual RS-232 transceiver)
- Single-supply operation: 4.5V–5.5V (5V typical)
- TTL/CMOS-compatible input levels; RS-232 level outputs
- Internal charge-pump voltage generator for RS-232 levels
- External capacitors required for the charge pump (typical values shown in datasheet)
- Extended temperature option: -40°C to +85°C
- Low quiescent current with protection features (short-circuit protection)
- 8-pin package (RoHS-compliant, EEWE suffix)
Note: For exact capacitor values and electrical characteristics, refer to the official MAX202EEWE datasheet.

Pinout

- Pin count: 16 pins (SOIC-16/DIP-16 commonly used)
- Function: Dual RS-232 transceiver (two drivers, two receivers) that converts TTL/CMOS UART levels to RS-232 levels and vice versa, using an internal charge pump (requires external capacitors) to generate the ± voltages.

Manufacturer

- Manufacturer: Maxim Integrated (now a subsidiary of Analog Devices)
- What kind of company: American semiconductor company specializing in analog and mixed-signal integrated circuits.

Application

MAX202EEWE is a dual RS-232 transceiver that converts TTL/CMOS UART levels to RS-232 levels (with internal charge pumps). Application areas include:
- Embedded systems and microcontroller serial interfaces
- Modems, routers, switches, and other network equipment
- POS terminals, printers, and cash registers
- Industrial instrumentation, data acquisition, and telemetry
- Debug/console ports on development boards and equipment
- Any device requiring a compact, low-pin RS-232 interface solution
