ICL3222CV-T

Overview

The ICL3222CV-T is a dual driver/receiver RS-232 transceiver from the Intersil series, designed for single-supply operation. It supports data rates up to 250 kb/s and operates within a voltage range of 3 V to 5.5 V. The device features a low power consumption profile with an operating supply current of 1 mA and includes a shutdown mode to minimize energy usage during idle periods. It provides 15 kV ESD protection on all pins and is housed in a 20-pin SSOP package.

Feature Summary

• Integrated dual drivers and receivers for full-duplex RS-232 communication
• Single-supply operation compatible with 3 V and 5 V logic levels
• Shutdown mode capability for significant power reduction
• Robust electrostatic discharge protection rated at 15 kV

Applications

• Portable battery-powered devices requiring low-power serial communication
• Industrial control systems utilizing RS-232 interfaces
• Embedded systems needing reliable data transmission with ESD resilience

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer designation as Intersil or Renesas Electronics, as ownership transitions may affect labeling. Ensure the component meets RoHS compliance requirements if mandated by your project specifications. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.

Selection Notes

Select this component for applications requiring dual-channel RS-232 connectivity with minimal power draw. The 250 kb/s speed is suitable for standard asynchronous serial links. Consider the SSOP-20 package dimensions for PCB layout constraints. Verify that the 3 V to 5.5 V supply range aligns with the system's available power rails.

Part Context

This part belongs to the ICL3222 family of RS-232 interface integrated circuits. It serves as a line transceiver converting TTL/CMOS levels to RS-232 voltages. The series is characterized by its ability to operate from a single power supply, eliminating the need for negative voltage generators typically required by older RS-232 standards.

Replacement Considerations

Check for ICL3222EIVZ-T or ICL3222EIAZ-T as potential alternatives with similar electrical characteristics. Verify package compatibility between SSOP-20 variants before substitution. Ensure the replacement part maintains the same 1 mA operating current and 15 kV ESD protection ratings.
