产品型号MAX3232的概述

芯片MAX3232的概述 MAX3232是由美国Maxim Integrated（现为Analog Devices）公司推出的一款广泛应用的双通道RS-232级别转换器。其设计目的是为了实现TTL（Transistor-Transistor Logic）与RS-232电平之间的转换，使用于串口通信的场合。RS-232标准广泛存在于计算机与外部设备之间的通信，其使用正负电压进行信号表示，而TTL则使用0V与5V（或3.3V）来表示数字信号。因此，一个高效、可靠的电平转换器对于保证通信的正确性和稳定性至关重要。 MAX3232芯片具有双通道设计，可以同时处理两个RS-232信号通道，为使用者提供了更大的灵活性。它具有较高的数据传输速率，适用于多种串行通信的应用场景，包括工业控制、嵌入式系统、计算机外围设备、调制解调器等。芯片MAX3232的详细参数 MAX3232的详细参数包括： - 电...

description

The MAX3232 device consists of two line drivers, two line receivers, and a dual charge-pump circuit with

±15-kV ESD protection pin to pin (serial-port connection pins, including GND). The device meets the

requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication

controller and the serial-port connector. The charge pump and four small external capacitors allow operation

from a single 3-V to 5.5-V supply. The devices operate at data signaling rates up to 250 kbit/s and a maximum

of 30-V/µs driver output slew rate.

The MAX3232C is characterized for operation from 0°C to 70°C. The MAX3232I is characterized for operation

from –40°C to 85°C.
