Overview

Description

MAX202CWE is Maxim’s dual RS-232 transceiver. It provides two RS-232 drivers and two receivers, allowing a microcontroller’s TTL/CMOS UART to communicate with RS-232 devices from a single 5V supply. It uses an on-chip charge pump to generate the required RS-232 voltage levels from the 5V rail; four external capacitors are typically required.
Key features (typical):
- 2 transmitter channels and 2 receiver channels
- Data rates up to about 120 kbps
- TTL/CMOS compatibility on the logic side; RS-232 levels on the signal side
- Low power relative to older RS-232 solutions
- Available in multiple package options
Common pin roles:
- TIN1/TIN2: TTL/CMOS inputs from the MCU
- TOUT1/TOUT2: RS-232 outputs to the serial port
- RIN1/RIN2: RS-232 inputs from the remote device
- ROUT1/ROUT2: TTL/CMOS outputs to the MCU
- VCC, GND: power and ground
Applications: PLCs and microcontrollers interfacing to PCs/modems, data-logging systems, embedded serial links.
Note: Check the datasheet for exact pinout and package options for the CWE variant.

Features

Here are typical features of the MAX202CWE RS-232 transceiver:
- 2 drivers and 2 receivers (2‑channel RS‑232 interface)
- Single-supply operation (approx 4.5–5.5 V) with internal charge pump for RS‑232 levels
- External capacitors required for the charge pump (low-value caps)
- TTL/CMOS compatible inputs
- Full RS‑232 level outputs (± voltages with proper drive)
- Data rates up to about 120 kbps
- 16-pin package (e.g., SSOP/DIP variants)
- Industrial temperature range: -40°C to +85°C
- ESD/short-circuit protection on RS‑232 lines
- Low quiescent current and fast power-up
Note: exact capacitor values and voltage ranges may vary by specific lot/packaging; consult the datasheet for the variant you have.

Package

MAX202CWE is in an 8-pin Small-Outline Integrated Circuit (SOIC) package (RoHS-compliant).

Pinout

Pin count: 8 pins (8-pin package).
Function: Dual RS-232 transceiver. It provides two TTL/CMOS-to-RS-232 drivers and two RS-232-to-TTL receivers, with an on-chip charge pump to generate RS-232 voltage levels. Used to connect a microcontroller’s UART to RS-232 serial ports.

Manufacturer

- Manufacturer: Maxim Integrated (now part of Analog Devices after the acquisition in 2021).
- Company type: A semiconductor company that designs and markets analog and mixed-signal integrated circuits.

Application

MAX202CWE is a dual RS-232 transceiver. Applications include:
- MCU/DSP to RS-232 interfaces; TTL/CMOS to RS-232 level shifting
- PC serial ports, modems, network equipment consoles
- Data acquisition, instrumentation, test gear
- Industrial automation (PLCs), POS terminals, printers
- Any embedded system needing low-power, 2-driver/2-receiver RS-232 transceivers

Equivalent

Equivalent RS-232 transceivers (2 drivers, 2 receivers, 5V supply):
- ADM202 (Analog Devices)
- SP3232 (Exar/Renesas)
- ST3232 (STMicroelectronics)
- MAX232 / MAX232E (Maxim)
- MAX3232 (Maxim)
These provide similar functionality with compatible pinouts and external capacitor requirements.
