ICL3232EIV-20Z

Overview

The ICL3232EIV-20Z is an RS-232 transceiver manufactured by Renesas Electronics Corporation, housed in a 20-TSSOP package. It features one driver and two receivers with full-duplex communication capabilities. The device supports data rates up to 500 kbps and operates on a single power supply ranging from 3 V to 5.5 V. It provides high electrostatic discharge (ESD) protection rated at 15 kV. The component functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated high ESD protection for robust signal integrity
• Single-supply operation compatible with standard voltage levels
• Industrial-grade thermal stability for demanding environments

Applications

• Industrial control systems requiring reliable serial communication
• Embedded devices needing protected RS-232 interfaces
• Data acquisition modules operating in electrically noisy environments

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm pinout and electrical characteristics match the design requirements. Confirm moisture sensitivity level handling procedures during assembly to prevent package damage. Ensure the 20-pin TSSOP footprint aligns with the PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this component when higher ESD tolerance is required compared to standard variants. Verify that the 20-pin package fits the available board space, as other family members may use 16-pin packages. Confirm that the 500 kbps speed meets the system's timing constraints and that the single driver configuration suits the application topology.

Part Context

This part belongs to the ICL3232 series of RS-232 transceivers designed for low-power applications. The series offers various packaging options and ESD protection levels. The ICL3232EIV-20Z specifically targets industrial environments with its extended temperature range and enhanced protection features, distinguishing it from commercial grade alternatives.

Replacement Considerations

Check for ICL3232CVZ or ICL3232IVZ if a 16-pin package is acceptable. Verify pin compatibility when substituting with other Renesas RS-232 devices. Ensure the replacement maintains the required ESD protection rating and operating temperature range.
