ICL3243CAZ

Updated: 2026-08-04

Overview

The ICL3243CAZ is a low-power RS-232 transceiver integrated circuit (IC) designed for industrial and embedded communication applications. Operating within a voltage range of 3.0V to 5.5V, it is optimized for power-sensitive environments while maintaining robust data transmission capabilities. This IC is commonly used in devices such as point-of-sale terminals, networking equipment, and industrial control systems where reliable serial communication is essential. Manufactured using advanced semiconductor technology, the ICL3243CAZ integrates multiple functions into a compact package, making it suitable for space-constrained designs. Its compatibility with standard RS-232 protocols ensures seamless integration into existing systems. The component is known for its reliability and is often preferred in applications requiring long-term stability and low maintenance.

Structure and Working Principle

The ICL3243CAZ consists of a transmitter and receiver pair that converts logic-level signals to RS-232 voltage levels and vice versa. The transmitter section typically operates at TTL/CMOS logic levels, while the receiver section can handle the higher voltage swings characteristic of RS-232 communication. Internal charge pumps generate the necessary voltage levels from a single power supply, eliminating the need for additional components. This IC employs ESD protection circuitry on its interface pins, safeguarding against electrostatic discharge events that could damage sensitive electronics. The low-power design reduces energy consumption, making it ideal for battery-operated or energy-efficient systems. Data rates up to 250kbps are supported, ensuring compatibility with a wide range of communication protocols and devices.

B2B Procurement Guide

When procuring the ICL3243CAZ in bulk, buyers should verify the authenticity of components to avoid counterfeit products. Reputable distributors and manufacturers should be prioritized, and certificates of compliance (e.g., RoHS, REACH) should be requested. Volume discounts are commonly available, so negotiating with suppliers for large orders can reduce costs. Lead times can vary depending on market demand, so placing orders well in advance is advisable for time-sensitive projects. Buyers should also confirm packaging options (e.g., tape and reel) to align with assembly requirements. Sample testing before large-scale procurement is recommended to ensure compatibility and performance.
