ICL3227EIA-T

Overview

The ICL3227EIA-T is a single-driver, single-receiver RS-232 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 1 Mb/s. The device features full-duplex communication in an SSOP-16 surface-mount package. Key electrical specifications include a maximum output current of 35 mA, a typical operating supply current of 1 mA, and ESD protection rated at 15 kV. The component functions across a commercial temperature range from 0°C to +70°C and includes a shutdown feature for power management.

Feature Summary

• Integrated single driver and receiver for full-duplex RS-232 communication
• Low power consumption with 1 mA typical operating supply current
• High electrostatic discharge (ESD) protection capability
• Shutdown mode functionality for energy efficiency

Applications

• Portable battery-powered instruments requiring low current draw
• Industrial control systems utilizing RS-232 serial interfaces
• Communication modules in embedded devices

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if required for automated assembly. Confirm RoHS compliance status through official datasheets as manufacturing sources may vary. Check for end-of-life notifications or obsolescence warnings directly from Renesas Electronics before finalizing procurement plans.

Selection Notes

Select this component when a single-channel RS-232 interface is sufficient for the design. Ensure the system voltage aligns with the 3 V to 5.5 V operating range. Consider the SSOP-16 package dimensions for PCB layout constraints. Verify that the 1 Mb/s data rate meets the application's speed requirements compared to lower-speed alternatives.

Part Context

This part belongs to the ICL3227E series of RS-232 transceivers. It is functionally similar to other single-driver variants in the family but distinguished by its specific packaging and thermal characteristics. The 'ICL' prefix historically denotes Intersil products now managed under Renesas Electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with MAX3227E or ICL3227ECAZA only if pin compatibility and electrical parameters are verified against official manufacturer substitution guides.
