MAX232ACPE+ RS-232 Transceiver IC – DIP-16

Description

The MAX232ACPE+ is a dual transmitter/receiver integrated circuit that serves as a level shifter between TTL/CMOS logic levels and the EIA/TIA-232 (RS-232) voltage levels. It is an essential component for serial communication, allowing microcontrollers and other digital devices to interface reliably with standard serial ports (COM ports).

The IC features an internal dual charge pump that converts a single 5V power supply into the positive and negative voltages required by the RS-232 standard ($\pm 10$ V). This eliminates the need for complex dual-polarity power supplies in serial communication circuits.

Note: Product images are for reference only. Please refer to the official datasheet for external capacitor values, as these are critical for the charge pump’s operation.

Features

• Dual Drivers/Receivers: Two independent channels for full-duplex communication.
• Internal Charge Pump: Generates $\pm 10$ V internally from a single +5V supply.
• Standard Compatibility: Fully meets EIA/TIA-232 standards.
• High Reliability: Industry-standard solution for TTL-to-RS232 conversion.
• Package: DIP-16 through-hole package, ideal for prototyping and breadboarding.

Benefits

• Simplifies serial hardware design by providing all necessary voltage conversions on-chip.
• Allows microcontrollers (3.3V or 5V logic) to communicate with legacy serial equipment like PCs, industrial controllers, and modems.
• Robust protection and stable performance in serial data transmission.
