ICL3232EFV-16Z

Overview

The ICL3232EFV-16Z is an RS-232 transceiver manufactured by Renesas Electronics, housed in a TSSOP-16 surface-mount package. It operates within a supply voltage range of 3 V to 5.5 V, supporting both 3.3 V and 5 V logic levels. The device features two drivers and two receivers with a data rate capability of 500 kb/s. It includes ±15 kV ESD protection on the bus pins and draws only 1 mA of operating power. The component functions across an extended industrial temperature range from -40 °C to +125 °C.

Feature Summary

• Provides dual transmit and receive channels for RS-232 communication
• Integrates high-level electrostatic discharge protection on interface pins
• Maintains low power consumption during active operation
• Supports reliable performance across wide industrial temperature extremes

Applications

• Industrial control systems requiring robust serial communication
• Portable instrumentation and battery-powered devices
• Data communication equipment interfaces
• Computer peripheral connections

Procurement Notes

This component is officially designated as End of Life (EOL) by the manufacturer. Distribution availability is restricted, and Mouser indicates non-sale status in certain regions. Verification of current stock or alternative sourcing channels is required before integration into new designs due to discontinuation status.

Selection Notes

Designers should evaluate the 500 kb/s data rate limit against system requirements. The TSSOP-16 package necessitates specific PCB footprint planning. Consider the extended temperature rating for harsh environments. Verify that the single-ended receiver inputs meet signal integrity needs for the target application topology.

Part Context

Part of the ICL3232 series, this device belongs to Renesas' portfolio of low-power RS-232 transceivers. It shares functional similarities with other members like the ICL3232EIV-16Z-T but differs in packaging and specific commercial availability status. The series is known for meeting EIA/TIA-232 standards without external components.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End of Life status, direct pin-to-pin replacements must be verified through official Renesas cross-reference tools or authorized distributor databases.
