MAX3232CPE+
Overview
The MAX3232CPE+ is a dual RS-232 transceiver that allows 3.0V to 5.5V logic systems to communicate with standard RS-232 serial ports. It features a proprietary low-dropout transmitter output stage and a dual charge pump that enables true RS-232 performance while operating from a single supply. This variant comes in a 16-pin plastic DIP package, making it ideal for prototyping and through-hole assembly.
Why Choose This Part
This IC operates with a very low supply current of 0.5mA typical, extending battery life in portable applications. It supports high-speed data rates up to 1Mbps and requires only four small 0.1uF external capacitors for the internal charge pump, saving significant board space. The 16-pin DIP package is specifically advantageous for breadboarding and easy manual soldering.
Applications
Getting Started
To use this device, connect four 0.1uF capacitors to the C1+, C1-, C2+, and C2- pins as specified in the datasheet to initialize the charge pump. Ensure VCC is between 3.0V and 5.5V, and connect your microcontroller UART TX/RX pins to the T1IN/R1OUT logic-side pins. Because this is a through-hole DIP component, it can be plugged directly into a standard solderless breadboard for rapid prototyping.
