ICL3223CV-T

Overview

The ICL3223CV-T is a dual driver/receiver RS-232 transceiver manufactured by Renesas/Intersil. It operates on a single 3 V to 5.5 V supply and supports data rates up to 250 kb/s in full-duplex mode. The device features an automatic power-down mode that reduces operating current to 1 µA when no valid signal is present. It includes integrated charge pumps requiring only external 0.1 µF capacitors. The component provides 15 kV ESD protection on RS-232 lines and is housed in a TSSOP-16 package.

Feature Summary

• Automatic power-down mode for low standby current consumption
• Integrated charge pumps eliminating need for external inductors
• High electrostatic discharge protection on all RS-232 pins
• Single-supply operation compatible with 3.3 V and 5 V systems

Applications

• Portable battery-powered equipment requiring low power consumption
• Industrial control systems with RS-232 communication interfaces
• Medical instrumentation utilizing serial data transmission
• Embedded systems connecting microcontrollers to PC ports

Procurement Notes

Verify the specific suffix CV-T against official datasheets to confirm the TSSOP-16 package and tape-and-reel delivery format. Confirm RoHS compliance status through manufacturer documentation as regulatory requirements vary by region. Check for obsolescence notices or lifecycle changes from Renesas Electronics prior to finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring dual RS-232 channels with minimal external capacitance. Ensure the application environment stays within the specified commercial temperature range of 0°C to +70°C. Verify that the system voltage remains between 3 V and 5.5 V to maintain signal integrity and proper charge pump operation.

Part Context

This part belongs to the ICL3223 series of low-power RS-232 transceivers. It shares functional similarities with other Intersil devices like the ICL3223ECAZ but differs in packaging and shipping configuration. The series is designed for applications prioritizing power efficiency without sacrificing communication reliability over standard serial links.

Replacement Considerations

Direct substitutes include the MAX3223E and SP3222E, which offer similar pinouts and electrical characteristics. Verify compatibility regarding capacitor values and shutdown pin configurations before swapping components in existing designs.
