ICL3226EIA

Overview

The ICL3226EIA is a single driver and receiver RS-232 transceiver manufactured by Renesas Electronics Corporation. It operates from a single power supply ranging from 3 V to 5.5 V, supporting both 3.3 V and 5 V logic levels. The device features low-power CMOS technology with an operating supply current of typically 10 µA in shutdown mode. It provides ±7.5 kV ESD protection on all pins according to the Human Body Model. The component is housed in a 16-pin SSOP package and is rated for industrial temperature operation between -40°C and +85°C.

Feature Summary

• Single driver and receiver configuration for point-to-point RS-232 communication
• Low-power operation with microamp-level shutdown current consumption
• Integrated electrostatic discharge protection on all signal pins

Applications

• Industrial control systems requiring serial data transmission
• Portable battery-powered equipment utilizing single-supply operation
• Communication interfaces in embedded systems with limited power budgets

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm package type and temperature range. Ensure the ordering part number matches the required industrial grade specifications. Cross-reference the manufacturer's latest datasheet to validate pinout compatibility and electrical characteristics before procurement.

Selection Notes

Select this component when a single channel of RS-232 communication is sufficient for the design. It is suitable for applications requiring low standby power and robust ESD immunity. Verify that the system voltage falls within the 3 V to 5.5 V operating range and that the SSOP package fits the PCB layout constraints.

Part Context

This part belongs to the ICL322x series of RS-232 transceivers designed for low-voltage applications. It serves as a bridge between microprocessor logic levels and RS-232 signal standards. The series is characterized by its ability to operate from a single supply without requiring negative voltage generation circuits.

Replacement Considerations

Check for direct replacements such as the MAX3226 or SP3226, which offer similar functionality. Verify pin compatibility and electrical parameters against the original specification sheet. Ensure any substitute component meets the same ESD protection and temperature rating requirements.
