ICL3232ECV-20Z

Overview

The ICL3232ECV-20Z is a dual driver/receiver RS-232 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3 V to 5.5 V, supporting both 3.3 V and 5 V logic systems. The device provides a data rate of 500 kb/s and features ±15 kV electrostatic discharge (ESD) protection on the bus pins. It is housed in a 20-pin TSSOP package designed for surface mount technology. The component draws a typical operating supply current of 1 mA and functions reliably across an industrial temperature range from 0 °C to +70 °C.

Feature Summary

• Integrated charge pump circuitry generates compliant RS-232 voltage levels directly from a single low-voltage power supply.
• Bus pins are protected against high-energy electrostatic discharge events up to ±15 kV.
• Designed for full duplex communication with two independent drivers and two receivers.

Applications

• Industrial control systems requiring robust serial communication interfaces
• Portable battery-powered equipment utilizing low-power RS-232 links
• Modems and peripheral devices interfacing with microprocessor-based systems

Procurement Notes

Verify the specific suffix Z for lead-free compliance and RoHS status before procurement. Confirm the EOL status indicated by Mouser, as availability may be restricted or limited to existing stock. Ensure the TSSOP-20 footprint matches the target PCB design constraints. Check moisture sensitivity level requirements for storage and reflow soldering processes.

Selection Notes

Select this component when a dual-channel RS-232 interface is required with moderate data rates up to 500 kb/s. It is suitable for applications needing ±15 kV ESD protection without external components. Compare against the ICL3232CVZ if a 16-pin package is preferred, noting the difference in driver count and pin configuration. Ensure the 3 V to 5.5 V supply range aligns with the system power architecture.

Part Context

This part belongs to the ICL3232 series of RS-232 transceivers produced by Renesas and formerly Intersil. The series includes variants like the ICL3232CVZ and ICL3232EIV-16Z-T, which differ primarily in package type and pin count. The ICL3232ECV-20Z specifically utilizes a 20-pin TSSOP form factor, distinguishing it from the 16-pin SOIC or TSSOP options available in the same functional family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consider checking for direct equivalents within the ICL3232 family, such as the ICL3232CVZ, while accounting for package and pin differences.
