ICL3226EIA-T

Overview

The ICL3226EIA-T is a single driver and receiver RS-232 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3 V to 5.5 V, supporting data rates up to 250 kb/s. The device features full-duplex communication capabilities with a typical operating supply current of 1 mA. It is housed in a 16-pin SSOP package designed for surface mount technology (SMD/SMT). The component functions reliably across an extended temperature range from -40°C to +85°C, providing robust serial communication interfaces for low-power applications.

Feature Summary

• Integrated charge pump circuitry eliminates the need for external capacitors in some configurations, simplifying board layout.
• Provides ESD protection rated at 15 kV according to specific industry standards, enhancing signal integrity reliability.
• Operates efficiently on a single 3 V to 5.5 V power supply, reducing system power consumption requirements.

Applications

• Portable battery-powered devices requiring low-current RS-232 connectivity
• Industrial control systems utilizing serial communication protocols
• Embedded systems interfacing with modems or peripheral equipment

Procurement Notes

Verify the exact suffix against official Renesas documentation to confirm packaging type and tape/reel specifications. Ensure the ordering part number matches the required moisture sensitivity level and RoHS compliance status. Cross-reference the manufacturer's latest datasheet revision to validate pinout compatibility and electrical characteristics before procurement.

Selection Notes

Select this component when a single-channel RS-232 interface is required with minimal external passive components. It is suitable for designs prioritizing low standby current and operation from a single 3 V or 5 V supply rail. Verify that the 250 kb/s data rate meets the application's speed requirements and that the SSOP-16 package fits the available PCB footprint constraints.

Part Context

This part belongs to the ICL3226 series of RS-232 transceivers, which are known for their low power consumption and ease of use. The series typically includes variants with different packaging options and temperature ranges. The ICL3226 specifically addresses the need for reliable serial communication in compact, battery-operated electronic devices.

Replacement Considerations

The MAX3226EEAE from Analog Devices is a functional equivalent with similar electrical specifications and pinout compatibility. Both devices offer single driver/receiver configurations and operate within the same voltage range. Verify package dimensions and thermal characteristics when substituting.
