Overview

Description

ADM232AARW is Analog Devices’ dual RS-232 transceiver. It provides two RS-232 drivers and two receivers that translate between TTL/CMOS logic levels and RS-232 voltage levels. It operates from a single 3.3–5.5 V supply and uses an internal charge-pump to generate the ± voltages required by RS-232, so no external ± supply is needed. External charge-pump capacitors are required (typical four). On the logic side, TTL/CMOS inputs drive the drivers; the receivers provide TTL/CMOS outputs. Suitable for microcontroller serial interfaces to PCs, modems, or other RS-232 devices. Features usually include robust RS-232 signaling, ESD protection, and low power consumption. The ARW suffix denotes the specific RoHS-compliant packaging option for Analog Devices parts.

Package

ADM232AARW uses an 8‑pin SOIC (Small Outline Integrated Circuit) package, RoHS compliant. The suffix RW typically indicates tape‑and‑reel packaging.

Pinout

8 pins (SOIC-8). Function: Dual RS-232 transceiver (two drivers and two receivers) that converts TTL/CMOS logic levels to RS-232 voltage levels and RS-232 levels back to TTL/CMOS; powered from a single supply (typical 5V) with GND.

Manufacturer

Manufacturer: Analog Devices, Inc. (Analog Devices).
What kind of company: A global semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits for a wide range of markets (industrial, automotive, communications, consumer electronics, etc.).

Application

Applications of ADM232AARW (RS-232 transceiver with charge pump):
- Embedded systems needing RS-232 interface (MCUs to PCs/serial peripherals)
- Serial console ports for networking gear (routers, switches, modems, servers)
- Industrial equipment (PLCs, data loggers, instrumentation, POS) requiring RS-232 signaling
- Lab/test equipment and portable devices with limited power/space
- General-purpose replacement for MAX232-style interfaces in 3.3V/5V single-supply designs

Equivalent

ADM232AARW is a 2-driver/2-receiver RS-232 transceiver. Drop-in equivalents include:
- MAX232 / MAX232A / MAX3232 (Maxim/Analog Devices)
- ST232 / ST3232 (STMicroelectronics)
- SP232 / SP3232 (Exar)
- ICL232 (Intersil)
Ensure matching supply range (typically 3–5 V) and capacitor size (0.1–1 µF) for proper compatibility.
