ICL3232ECAZ

Overview

The ICL3232ECAZ is a low-power RS-232 transceiver manufactured by Renesas Electronics. It integrates two drivers and two receivers, supporting full-duplex communication with data rates up to 250 kb/s. The device operates on a single power supply ranging from 3 V to 5.5 V, with a typical quiescent current of 1 mA. It features 15 kV electrostatic discharge (ESD) protection on all pins. The component is housed in a 16-pin SSOP package and is rated for an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrated dual driver and dual receiver architecture for full-duplex serial communication
• High ESD protection rating of 15 kV across all signal pins
• Low power consumption with 1 mA typical operating current
• Single-supply operation compatible with 3.3 V and 5 V logic levels

Applications

• Industrial control systems requiring reliable serial communication
• Point-of-sale terminals and barcode scanners
• Medical equipment with serial interface requirements
• Embedded systems utilizing RS-232 protocols

Procurement Notes

Verify the specific suffix 'AZ' against the manufacturer's datasheet to confirm lead-free status and RoHS compliance. Ensure the SSOP-16 package dimensions match the target PCB footprint. Confirm that the commercial temperature range (0°C to +70°C) meets the operational environment requirements before finalizing procurement.

Selection Notes

Select this component when a dual-channel RS-232 interface is required within a compact SSOP-16 form factor. It is suitable for applications needing moderate data rates up to 250 kb/s. Consider alternative packages like SOIC or TSSOP if pin compatibility differs. Verify voltage tolerance if the system operates near the 5.5 V maximum limit.

Part Context

This part belongs to the ICL3232 series of RS-232 transceivers. It shares functional similarities with other devices in the family but is distinguished by its specific package type and commercial temperature rating. The 'ECAZ' designation indicates the specific pinout, package style, and environmental compliance attributes defined by Renesas.

Replacement Considerations

Direct substitutes include ICL3232EIAZ and ICL3232CVZ. Verify pin compatibility and package dimensions before substitution. Ensure the replacement part supports the same voltage range and data rate specifications.
