Overview
The ICL3223EIA is a dual-driver, dual-receiver RS-232 transceiver from the Intersil ICL32xxE series. It operates on a single +3.0V to +5.5V supply and meets EIA/TIA-232 and V.28/V.24 specifications at 3.0V. The device features ±15kV ESD protection on RS-232 pins, an internal charge pump requiring only four small capacitors, and automatic powerdown functionality that reduces standby current to 1µA. It supports data rates up to 250kbps (guaranteed) and higher typical speeds, housed in a 20-pin SSOP package.
Feature Summary
- Integrated automatic powerdown circuitry for ultra-low standby current consumption
- Robust ±15kV electrostatic discharge protection on all RS-232 input and output pins
- Single-supply operation compatible with 3.3V and 5.0V systems without level shifting
Applications
- Portable computers and notebook PCs requiring low-power serial communication
- Battery-operated handheld devices and PDAs
- Industrial peripherals connecting to host systems via RS-232 interfaces
Procurement Notes
Verify component authenticity through authorized Renesas or Intersil distributors. Confirm RoHS compliance status and specific suffix designations against official datasheets. Check for moisture sensitivity levels and storage conditions prior to soldering. Ensure the package type matches the intended PCB footprint requirements.
Selection Notes
Select this component when designing for 3V to 5.5V systems requiring full-duplex RS-232 communication. It serves as a direct pin-compatible replacement for older 5V MAX221E/HIN232 devices. Choose this part if automatic powerdown is required to extend battery life in portable applications.
Part Context
The ICL3223EIA belongs to the ICL32xxE family of low-power RS-232 transceivers manufactured by Intersil, now part of Renesas Electronics. This series was designed to replace legacy 5V RS-232 chips with lower voltage alternatives while maintaining compatibility with standard RS-232 signaling levels and protocols.
Replacement Considerations
Publicly confirmed pin-compatible replacements include the MAX3221E and MAX3222E. Designers should verify electrical parameter tolerances and operating temperature ranges when substituting these components.
