ICL3225ECAZ

Overview

The ICL3225ECAZ-T is a single-driver, dual-receiver RS-232 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 1 Mbps. The device features enhanced automatic powerdown circuitry that reduces operating current to approximately 1 µA when no signal activity is detected. It provides ±15 kV electrostatic discharge (ESD) protection on all RS-232 lines. The component is housed in a 20-pin SSOP package and is rated for an industrial temperature range from 0 °C to +70 °C.

Feature Summary

• Enhanced automatic powerdown functionality minimizes power consumption during idle periods
• Integrated ±15 kV ESD protection safeguards inputs and outputs against static discharge
• Single-ended output configuration compatible with standard RS-232 signaling requirements

Applications

• Industrial control systems requiring low-power serial communication
• Portable battery-operated equipment utilizing RS-232 interfaces
• Embedded systems needing robust ESD protection for external connections

Procurement Notes

Verify the specific suffix designation upon ordering, as the ICL3225ECAZ typically denotes tube packaging while the ICL3225ECAZ-T indicates tape-and-reel format. Confirm moisture sensitivity level handling procedures are followed during assembly. Ensure the selected variant matches the required driver and receiver count for the target design.

Selection Notes

Select this component when a single transmitter and two receivers are sufficient for the application. Compare against the ICL3223E for dual-driver configurations or the ICL3221E for single-driver/single-receiver needs. Verify that the 1 Mbps data rate meets system timing requirements and that the SSOP package fits the available PCB footprint constraints.

Part Context

This part belongs to the Intersil ICL32XXE family of RS-232 transceivers, now produced under Renesas Electronics following corporate acquisitions. The series is characterized by low standby current and high ESD tolerance, distinguishing it from older generations lacking automatic powerdown features. It serves as a direct replacement for legacy Intersil parts in existing designs.

Replacement Considerations

The ICL3225EIAZ-T is a verified alternative offering an extended commercial temperature range of -40 °C to +85 °C compared to the industrial range of the ECAZ variant. Both parts share identical pinouts and electrical specifications.
