ICL3232ECV-20

Overview

The ICL3232ECV-20 is an RS-232 transceiver manufactured by Intersil, now part of Renesas Electronics. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 500 kb/s. The device integrates one driver and two receivers in a TSSOP-20 surface-mount package. It features 15 kV electrostatic discharge (ESD) protection on all RS-232 lines. The component draws a typical operating supply current of 1 mA and functions reliably across a commercial temperature range from 0°C to +70°C.

Feature Summary

• Integrated dual charge pump requiring only four small external capacitors for operation
• High ESD protection rating of 15 kV on all RS-232 input/output pins
• Low power consumption with 1 mA typical supply current
• Single-ended receiver inputs compatible with standard RS-232 signaling

Applications

• Industrial control systems requiring robust serial communication
• Portable battery-powered equipment utilizing 3V logic supplies
• Data acquisition modules interfacing with PC serial ports
• Embedded systems needing isolated RS-232 connectivity

Procurement Notes

Verify the exact suffix designation, as the provided model lacks the final character found in public listings like ICL3232ECV-20Z. Confirm RoHS compliance status and moisture sensitivity level before procurement. Check for end-of-life notices or obsolescence warnings from the manufacturer. Ensure the TSSOP-20 package footprint matches the design layout. Validate that the 0°C to 70°C commercial temperature range meets the application requirements.

Selection Notes

Select this component when a single driver and dual receivers are required in a compact TSSOP-20 form factor. It is suitable for designs prioritizing low power consumption alongside high ESD immunity. Compare against variants with shutdown modes if power management during idle states is critical. Ensure the 500 kb/s data rate capability aligns with the system's communication speed needs.

Part Context

This part belongs to the ICL3232 series of low-power RS-232 transceivers. It shares architectural similarities with other members like the ICL3232ECV-16Z but differs in pin count and configuration. The series is characterized by its ability to operate from a single 3V to 5.5V supply without requiring negative voltages. It represents a transition point between legacy Intersil products and modern Renesas offerings.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific variant are not available in the provided documentation. Consider evaluating the ST3232EC for similar performance characteristics. Verify compatibility with existing circuit designs before substituting with generic RS-232 transceivers.
