Product Introduction

Overview

The MAX232IDWR is a dual driver/receiver integrated circuit produced by Texas Instruments. It is designed to facilitate communication between TTL/CMOS logic levels and the RS232 serial communication standard. The device includes a capacitive voltage generator that allows it to operate from a single 5V power supply, generating the necessary voltage levels for RS232 communication.
