ICL3243IAZ-T

Overview

The ICL3243IAZ-T is an RS-232 interface integrated circuit manufactured by Renesas Electronics, formerly Intersil. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 500 kb/s. The device integrates three drivers and five receivers, providing full duplex communication capabilities. It is housed in a 28-pin SSOP package and is designed for industrial temperature ranges from -40°C to +85°C. The component features low power consumption with a typical operating supply current of 1 mA.

Feature Summary

• Integrates three independent drivers and five independent receivers for multi-port serial communication
• Supports standard RS-232 protocols including EIA/TIA-232 and V.28/V.24 specifications
• Operates on a single 3 V to 5.5 V power supply without requiring external negative voltage generation

Applications

• Industrial control systems requiring multiple RS-232 connections
• Data acquisition equipment with serial communication interfaces
• Embedded systems utilizing microcontrollers for serial data transmission

Procurement Notes

Verify the exact part number suffix against official Renesas documentation to confirm package type and temperature grade. Confirm RoHS compliance status through the manufacturer's environmental declaration. Check for obsolescence notices or lifecycle changes directly from the supplier before procurement planning.

Selection Notes

Select this component when three transmit and five receive channels are required in a compact SSOP package. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range. Verify that the system power supply remains stable between 3 V and 5.5 V to maintain signal integrity.

Part Context

This component belongs to the ICL3243 series of RS-232 transceivers. It is part of Renesas Electronics' portfolio of interface solutions derived from Intersil technology. The series focuses on low-power, single-supply operation for serial communication applications in industrial and commercial environments.

Replacement Considerations

Consult official substitution guides for equivalent parts with matching driver/receiver counts and package dimensions. Verify pin compatibility and electrical specifications before replacing.
