ICL3225ECPZ

Overview

The ICL3225ECPZ is a dual driver, dual receiver RS-232 transceiver manufactured by Intersil (Renesas). It operates within a supply voltage range of 3.0V to 5.5V and supports data rates up to 1 Mbps. The device features enhanced automatic powerdown functionality, reducing operating supply current to 1 mA in active mode and significantly lowering standby consumption. It provides ±15kV ESD protection on RS-232 pins per IEC61000-4-2 standards. Packaged in a 20-pin PDIP format for through-hole mounting, it functions as a single-ended output transceiver compliant with EIA/TIA-232 specifications.

Feature Summary

• Enhanced automatic powerdown circuitry reduces standby power consumption when no valid RS-232 signal is detected.
• Integrated charge pumps enable operation from a single low-voltage supply without requiring external negative voltages.
• Robust electrostatic discharge protection rated at ±15kV ensures reliability in high-interference environments.

Applications

• Portable computers and notebook systems requiring low-power serial communication interfaces.
• Industrial control systems utilizing RS-232 protocols for data transmission.
• Embedded devices needing reliable serial connectivity with minimal power draw.

Procurement Notes

Verify the specific suffix 'CPZ' confirms the PDIP-20 package and commercial temperature range during sourcing. Confirm RoHS compliance status matches project requirements. Ensure the supplier source aligns with Renesas or authorized distribution channels to guarantee component authenticity and traceability.

Selection Notes

Select this component for designs requiring through-hole integration with 1 Mbps throughput. Compare against ICL3225EIAZ if surface-mount SSOP packaging or extended industrial temperature ranges are necessary. Evaluate capacitor requirements based on the specific charge pump configuration needed for the target supply voltage.

Part Context

This part belongs to the ICL32XXE family of 3V to 5.5V RS-232 transceivers. It shares core electrical characteristics with other members like the ICL3227E but differs in pinout and driver/receiver counts. The 'E' designation indicates enhanced features such as improved ESD protection and lower power consumption compared to legacy non-E series parts.

Replacement Considerations

Publicly confirmed substitutes include the ICL3225EIAZ for surface-mount applications. Verify compatibility with MAX207E or HIN207E equivalents if pin-to-pin replacement is required in existing designs, ensuring voltage and speed specifications match.
