Overview

Description

MAX3223CPWR is a Maxim RS-232 transceiver (driver/receiver) device. It provides a one-chip interface between a microcontroller’s TTL/CMOS UART and an RS-232 serial port by:
- Translating TTL/CMOS signals to RS-232 voltage levels and vice versa
- Using an internal charge-pump to generate the required RS-232 voltages from a single-supply
- Operating from a single supply (typ. 3.0–5.5 V) with minimal external components
- Handling multi-channel configurations in the MAX3223 family (the device variant packages multiple RS-232 channels in one IC)
- Offering low power consumption and standard RS-232 data rates for embedded serial applications
Typical uses include connecting microcontrollers or digital signal processors to PC serial ports, modems, and other RS-232 peripherals. The -CPWR suffix denotes a RoHS-compliant, tape-and-reel packaging variant.

Features

Here are the key features of MAX3223CPWR (RS-232 transceiver, 3-channel):
- Three RS-232 driver/receiver pairs (3 TX, 3 RX)
- Single-supply operation: 3.0V to 5.5V
- Internal charge-pump to generate RS-232 levels (requires four external capacitors, typically 0.1 µF)
- TTL/CMOS-compatible logic inputs
- True RS-232 output swing for standard interfaces
- Low quiescent current with programmable/shutdown options to save power
- ESD/overvoltage protection on RS-232 lines
- Suitable for standard RS-232 data rates (high-speed, multi-channel operation)
- RoHS-compliant, lead-free package (CPWR) in a compact package
Note: exact package type and temperature range are per the datasheet; confirm for your board footprint.

Package

MAX3223CPWR uses a 16-pin plastic small‑outline package (SOIC) for surface-mount.

Pinout

- Pin count: 20 pins (package variants like SOP-20/TSSOP-20).
- Function: A triple RS-232 transceiver (three drivers and three receivers) with a built-in charge pump; converts TTL/CMOS logic levels to RS-232 levels and vice versa, powered from a single supply (3.0–5.5 V).

Manufacturer

MAX3223CPWR is manufactured by Maxim Integrated (now part of Analog Devices). Maxim is a fabless semiconductor company that designs and sells analog and mixed-signal integrated circuits.

Application

MAX3223CPWR is a multi-channel RS-232 transceiver. Applications include:
- Microcontroller/embedded systems connecting to RS-232 devices (PCs, modems, serial printers)
- Industrial/instrumentation equipment (PLCs, data loggers, test gear)
- Networking/telecom gear with serial consoles (routers, switches, gateways)
- Point-of-sale terminals and handheld scanners
- Any low-power, single-supply (3.3V/5V) RS-232 level-shifting need.

Equivalent

Common equivalents (2-driver, 2-receiver RS-232 transceivers) that operate from 3.0–5.5 V include:
- STMicroelectronics ST232C
- Renesas/Exar SP3232 (SP3232E)
- Analog Devices ADM3223
Note: check pinout/package (e.g., SO-16), drive strength, charge-pump capacitor needs, and timing to ensure proper substitution.
