ICL3232IVZ

Overview

The ICL3232IVZ is a full-duplex RS-232 transceiver manufactured by Renesas Electronics Corporation. It integrates two drivers and two receivers within a 16-pin TSSOP surface-mount package. The device operates on a single 3V to 5.5V power supply and supports data rates up to 250kbps. Key electrical specifications include a receiver hysteresis of 300mV and ±15kV ESD protection on all pins. It functions within an industrial temperature range of -40°C to +85°C, drawing a typical supply current of 1µA in shutdown mode.

Feature Summary

• Compliance with EIA/TIA-232 and V.28/V.24 interface standards for reliable serial communication
• Integrated charge pump circuitry eliminates the requirement for external positive and negative voltage supplies
• Robust electrostatic discharge protection rated at ±15kV on driver outputs and receiver inputs
• Ultra-low power consumption capability with a dedicated shutdown mode reducing supply current to approximately 1µA

Applications

• Industrial control systems requiring robust serial communication interfaces
• Portable battery-powered equipment utilizing low-voltage logic levels
• Modem and telecommunications terminal equipment
• Point-of-sale (POS) terminals and barcode scanners

Procurement Notes

Verify the specific suffix 'IVZ' to confirm the 16-TSSOP package variant and industrial temperature rating (-40°C to +85°C). Ensure compatibility with RoHS3 directives if environmental compliance is required. Cross-reference datasheet revision numbers to confirm pinout consistency with existing designs. Confirm moisture sensitivity level (MSL 3) handling requirements during assembly.

Selection Notes

Select this component when a dual-channel RS-232 solution is needed in a compact surface-mount footprint. It is suitable for designs operating between 3V and 5.5V where external bipolar supplies are unavailable. Consider the 250kbps speed limit for high-speed applications; higher speeds may require alternative devices. Verify that the 300mV receiver hysteresis meets noise immunity requirements for the specific environment.

Part Context

This part belongs to the ICL3232 family of RS-232 transceivers from Renesas (formerly Intersil). It shares functional similarities with the ICL3232E series but differs in packaging and specific feature sets like ESD ratings. The IVZ suffix specifically denotes the TSSOP-16 package configuration. It serves as a direct replacement for legacy MAX3232 equivalents in space-constrained PCB layouts.

Replacement Considerations

• ICL3232IBNZ: SOIC-16 package variant
• ICL3232EIVZ: Enhanced ESD protection variant
• ICL3232CVZ: Commercial temperature grade variant
