TI’s MAX232 is a 5-V dual channel 120kbps RS-232 line driver/receiver with +/-9V output & +/-2-kV ESD protection. Find parameters, ordering and quality information

The MAX220–MAX249 family of line drivers/receivers is intended for all EIA/TIA-232E and V.28/V.24 communications interfaces, particularly applications where ±12V is not available.. The MAX225, MAX233, MAX235, and MAX245/MAX246/MAX247 use no external components and are recommended for applications where printed circuit board space is critical.

The MAX232 is an integrated circuit by Maxim Integrated Products, now a subsidiary of Analog Devices, that converts signals from a TIA-232 (RS-232) serial port to signals suitable for use in TTL-compatible digital logic circuits. The MAX232 is a dual transmitter / dual receiver that typically is used to convert the RX, TX, CTS, RTS signals.

The MAX232 device is a dual driver/receiver that includes a capacitive voltage generator to supply TIA/ EIA-232-F voltage levels from a single 5V supply. Each receiver converts TIA/EIA-232-F inputs to 5V TTL/CMOS levels. These receivers have a typical threshold of 1.3 V, a typical hysteresis of 0.5V, and can accept ±30V inputs.

max232 器件是一款双路驱动器/接收器，其中包括一个电容式电压发生器，可通过单个 5v 电源提供 tia/eia-232-f 电压电平。 每个接收器都将 TIA/EIA-232-F 输入转换为 5V TTL/CMOS 电平。

2018年9月11日 · 本文详细介绍了RS232串口通信的基本概念和技术细节，包括接口标准、电气特性、通信参数设置、通信原理等内容。 此外还对比了RS232与RS485、RS422的不同之处。 一. 简介. RS232接口是标准串行接口，其通讯距离小于15 m，传输速率小于20 kb/s。 RS232标准是按负逻辑定义的，他的“1”电平在-5～-15 V之间，“0”电平在+5～+15 V之间。 虽然RS232应用很广，但由于数据传输速率慢，通讯距离短，特别是在100 m以上的远程通讯中难以让人满意，因此通 …

What is MAX232 IC? MAX232 IC is widely used for serial communication among Microcontrollers & PC. The main function of this integrated circuit is to change the logic levels of TTL/CMOS to RS232 throughout the serial communication process.

The MAX202E–MAX213E, MAX232E/MAX241E line drivers/receivers are designed for RS-232 and V.28 communications in harsh environments. Each transmitter output and receiver input is protected against ±15kV electrostatic discharge (ESD) shocks, without latchup.

MAX220–MAX249系列线驱动器/接收器，专为EIA/TIA-232E以及V.28/V.24通信接口设计，尤其是无法提供12V电源的应用。 MAX225、MAXX233、MAX235以及MAX245/MAX246/MAX247不需要外部元件，推荐用于印刷电路板面积有限的应用。 MAX220–MAX249现有26种不同封装，可操作温度范围从0至+70C，也可达到-55C至+125C.

2022年9月5日 · What is MAX232 IC? Microcontrollers and PCs frequently communicate serially using the MAX232 IC. This integrated circuit’s primary job is to convert TTL/CMOS logic values to RS232 during the serial communication process.
