概述
Description
ADM232AARW is Analog Devices’ dual RS-232 transceiver. It provides two drivers and two receivers to connect a UART (TTL/CMOS) to RS-232 serial lines, enabling reliable bidirectional communication.
Key points:
- Single-supply operation (typical 3.0–5.5 V) with an onboard charge-pump to generate RS-232 levels (external pump capacitors required).
- Two full RS-232 channels, suitable for typical UART data rates.
- Produces standard RS-232 voltage swings (approximately ± voltages) for robust long-distance signaling.
- Packaging: RoHS-compliant 16-pin package (e.g., SOIC/TSSOP) in tape-and-reel options.
Common uses:
- Microcontroller-to-PC serial interfaces
- Embedded systems and industrial equipment
- Any application needing simple, low-pin-count RS-232 connectivity
Note: For exact electrical specs, programming limits, capacitor values, and package details, refer to the ADM232AARW datasheet.

Pinout
- Pin count: 8 pins (8-pin package)
- Function: Single-channel RS-232 transceiver (one transmitter and one receiver) that converts TTL/CMOS logic to RS-232 levels and RS-232 levels back to TTL, using a charge-pump to generate the required RS-232 voltages.
