ICL3232EIV-16Z

Overview

The ICL3232EIV-16Z is a dual RS-232 transceiver manufactured by Renesas Electronics Corporation, designed for full-duplex data communication. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 250 kb/s. The device features two drivers and two receivers with a propagation delay of 150 ns and an output current capability of 35 mA. It incorporates ±15 kV ESD protection on all pins and functions reliably across an industrial temperature range from -40 °C to +85 °C. Packaged in a TSSOP-16 surface-mount format, it meets EIA/TIA-232 and V.28/V.24 specifications without requiring external shutdown control.

Feature Summary

• Integrated high-level electrostatic discharge protection rated at ±15 kV on all signal pins to enhance system robustness.
• Capable of maintaining compliance with EIA/TIA-232 standards even when operating at lower supply voltages near the minimum threshold.
• Provides full-duplex communication channels with dedicated driver and receiver sections for reliable serial data transmission.

Applications

• Industrial equipment requiring robust serial communication interfaces under harsh environmental conditions.
• Portable battery-powered devices utilizing low-voltage power supplies for efficient operation.
• Computer peripheral connections adhering to standard RS-232 signaling protocols.

Procurement Notes

Verify the specific suffix 'IV' against official Renesas documentation to confirm package type and temperature grade alignment. Ensure compatibility with existing PCB footprints for TSSOP-16 components. Cross-reference moisture sensitivity levels and recommended soldering profiles during assembly planning. Confirm that the intended application environment falls within the specified -40 °C to +85 °C operational range for optimal performance reliability.

Selection Notes

Select this component when a dual-channel RS-232 interface is required with integrated ESD protection. It is suitable for designs needing operation between 3 V and 5.5 V without external charge pumps. Consider alternatives if higher data rates exceeding 250 kb/s or shutdown functionality are necessary. Verify pinout compatibility with legacy Intersil designs if migrating from previous generations.

Part Context

This part belongs to the ICL3232E series of RS-232 transceivers, which are widely used for serial communication interfacing. The series includes variants with different packaging options such as SOIC and SSOP. The 'IV' designation typically indicates the TSSOP package variant. This family is known for eliminating the need for external capacitors in some configurations, although standard applications may still require them.

Replacement Considerations

The ICL3232EIBNZ serves as a direct functional substitute offering identical electrical characteristics but housed in an SOIC-16 package instead of TSSOP-16. Designers must verify footprint differences before swapping these packages. Other members of the ICL32xxE family may provide similar functionality but often differ in driver/receiver counts or additional features like shutdown modes.
