ICL3232EIV-16

Overview

The ICL3232EIV-16 is a dual driver and dual receiver RS-232 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3 V to 5.5 V, ensuring compatibility with 3.0V, 3.3V, and 5.0V systems. The device supports data rates up to 250 kb/s and features ±15 kV electrostatic discharge (ESD) protection on both transmitter outputs and receiver inputs. Packaged in a TSSOP-16 surface-mount format, it draws a typical operating current of 1 mA. Key electrical parameters include a propagation delay of 150 ns and an output current capability of 35 mA.

Feature Summary

• Provides ±15 kV ESD protection on RS-232 pins for enhanced signal integrity
• Operates reliably at low supply voltages down to 3.0 V
• Supports full-duplex communication with two drivers and two receivers

Applications

• Portable computers and laptops requiring low-power serial interfaces
• Personal digital assistants (PDAs) and handheld devices
• Industrial control systems with mixed voltage environments

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm exact package type and temperature grade. Ensure the ordering part number matches the required industrial or commercial specifications. Confirm moisture sensitivity levels and recommended soldering profiles prior to assembly.

Selection Notes

Select this component when a dual-channel RS-232 interface is needed with robust ESD protection. It is suitable for designs requiring operation across 3V to 5.5V ranges without external charge pump components for basic functionality. Compare pinout compatibility with existing PCB layouts before finalizing the design.

Part Context

This device belongs to the ICL3232E series of RS-232 transceivers. It is designed to meet EIA/TIA-232 and V.28/V.24 standards even at lower supply voltages. The series targets applications where power consumption and board space are critical constraints.

Replacement Considerations

Check for direct pin-compatible alternatives such as the MAX3232 or SP3232 series. Verify that substitute parts maintain the same 3V to 5.5V operating range and ESD protection ratings.
