ICL3226IAZ

Overview

The ICL3226IAZ is a single driver and receiver RS-232 transceiver manufactured by Renesas Electronics (formerly Intersil). It operates within a supply voltage range of 3 V to 5.5 V, supporting both 3.3 V and 5 V logic systems. The device achieves data rates up to 500 kb/s while maintaining low power consumption with a typical operating supply current of 1 mA. It is housed in an SSOP-16 surface-mount package and is rated for an industrial temperature range from -40 °C to +85 °C.

Feature Summary

• Integrates one driver and one receiver for full-duplex RS-232 communication
• Provides ESD protection capabilities on all pins
• Designed for low-power applications with minimal supply current draw

Applications

• Industrial control systems requiring serial communication
• Portable battery-powered equipment due to low power consumption
• Embedded systems interfacing with RS-232 peripherals

Procurement Notes

Verify the specific suffix 'IAZ' to confirm the industrial temperature grade (-40 °C to +85 °C) and tube packaging format. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor specifications before integration into production designs.

Selection Notes

Select this component when a single-channel RS-232 interface is required for industrial environments. Ensure the design supports the 3 V to 5.5 V supply range and utilizes an SSOP-16 footprint. Consider higher ESD-rated variants if exposure exceeds standard industrial limits.

Part Context

This part belongs to the ICL3226 series of RS-232 transceivers. It shares functional similarities with other single-driver devices in the family but is distinguished by its specific temperature rating and packaging configuration defined by the 'IAZ' designation.

Replacement Considerations

The ICL3226EIAZ offers similar functionality but includes enhanced 15 kV ESD protection. Verify if the increased ESD rating is necessary for the target application environment.
