ICL3223EIV-T

Overview

The ICL3223EIV-T is a low-power RS-232 transceiver manufactured by Renesas Electronics Corporation, belonging to the ICL32xxE series. It features two drivers and two receivers for full-duplex communication with a data rate of 250 kb/s. The device operates on a single power supply ranging from 3 V to 5.5 V, consuming only 1 mA of operating current. It includes an automatic shutdown mode that reduces power consumption when no signal is present. The IC provides 15 kV ESD protection on all RS-232 lines and is housed in a TSSOP-20 package suitable for surface mount installation.

Feature Summary

• Integrated automatic power-down mode activates during idle periods to minimize energy usage
• Built-in electrostatic discharge protection rated at 15 kV across all RS-232 interface pins
• Single-supply operation compatible with both 3.3 V and 5 V logic levels

Applications

• Industrial control systems requiring reliable serial communication
• Portable battery-powered equipment needing low standby current
• Embedded devices interfacing with PC serial ports or modems

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm pinout compatibility and temperature range. Ensure moisture sensitivity level handling procedures are followed during assembly. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status matches project requirements before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require dual-channel RS-232 connectivity with minimal power draw. The TSSOP-20 package offers a compact footprint for space-constrained layouts. Consider the 250 kb/s speed limit when evaluating high-speed data transmission needs. Verify that the 15 kV ESD rating meets the environmental protection standards of the target application site.

Part Context

This part belongs to the ICL32xxE family of CMOS RS-232 transceivers designed for low-voltage applications. It succeeds earlier Intersil designs under the Renesas Electronics portfolio. The device maintains electrical compatibility with standard EIA/TIA-232 and V.28/V.24 specifications while offering improved power efficiency over legacy solutions.

Replacement Considerations

ICL3222EIVZ-T serves as a functional substitute within the same series.
