Product Introduction

Overview

The MAX232IN, produced by Texas Instruments, is a dual EIA-232 driver and receiver integrated circuit. This device is designed to facilitate communication between TTL/CMOS logic levels and the EIA-232-F standard used in serial communication interfaces. The MAX232IN operates from a single 5V power supply and includes a capacitive voltage generator to produce the necessary voltage levels for EIA-232-F compliance.
