ICL3222ECA-T

Overview

The ICL3222ECA-T is a dual driver, dual receiver RS-232 transceiver from the Intersil ICL3222 series. It operates on a single 3 V to 5.5 V supply and supports full-duplex communication at data rates up to 250 kb/s. The device features 15 kV ESD protection and includes an automatic shutdown mode that reduces power consumption by disabling drivers and receivers when no valid signal is present. It is housed in a 20-pin SSOP package and is rated for commercial temperature ranges.

Feature Summary

• Integrates two independent drivers and two receivers for full-duplex RS-232 communication.
• Features automatic power-down functionality to minimize current consumption during idle states.
• Provides robust electrostatic discharge protection rated at 15 kV.

Applications

• Industrial control systems requiring reliable serial communication.
• Portable battery-powered equipment utilizing low-voltage logic interfaces.
• Data acquisition modules interfacing with RS-232 peripherals.

Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm package type and temperature range. Ensure the ordering code matches the required pin configuration and operational specifications. Cross-reference the component marking with official datasheets to prevent substitution errors during assembly.

Selection Notes

Select this component for applications requiring dual-channel RS-232 connectivity within a compact surface-mount footprint. Consider the 3 V minimum supply voltage for compatibility with modern low-power microcontrollers. Evaluate the 250 kb/s speed limit against system timing requirements before finalizing the design.

Part Context

This part belongs to the ICL3222 family of RS-232 interface integrated circuits manufactured by Intersil, now part of Renesas Electronics. The series is designed to provide cost-effective solutions for serial communication needs in embedded systems and industrial environments.

Replacement Considerations

Check for direct substitutes such as the MAX3222 or SP3222 series. Verify pin compatibility and electrical parameters before replacing the original component to ensure circuit functionality remains intact.
