ICL3232IVZ-T7A

Overview

The ICL3232IVZ-T7A is a full-duplex RS-232 transceiver manufactured by Renesas Electronics Corporation. It integrates two drivers and two receivers within a single package, supporting data rates up to 250 kbps. The device operates on a single power supply ranging from 3V to 5.5V and draws a typical operating current of 1 mA. It features receiver hysteresis of 300 mV for noise immunity and provides ±15kV ESD protection on all pins. The component is housed in a 16-TSSOP surface-mount package with a width of 4.40 mm and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual drivers and dual receivers for complete full-duplex RS-232 communication capabilities.
• Provides robust electrostatic discharge protection rated at ±15kV on all interface pins.
• Features receiver input hysteresis to enhance signal integrity in noisy environments.
• Designed for low-power operation with minimal supply current consumption during active use.

Applications

• Industrial control systems requiring reliable serial communication interfaces.
• Embedded devices utilizing microcontrollers for RS-232 data exchange.
• Portable equipment powered by single-cell lithium or alkaline batteries.
• Communication modules in automotive diagnostic tools.

Procurement Notes

Verify the specific suffix T7A to confirm tape-and-reel packaging configuration. Ensure compatibility with RoHS3 standards if environmental compliance is required. Check moisture sensitivity level (MSL 3) requirements for storage and handling procedures. Confirm the manufacturer designation as Renesas Electronics Corporation to avoid counterfeit components. Validate the 16-TSSOP footprint dimensions against PCB layout specifications before ordering.

Selection Notes

Select this component when full-duplex RS-232 connectivity is necessary with low power constraints. The 250 kbps speed suits most standard serial applications but may be insufficient for high-speed needs. The 3V to 5.5V supply range offers flexibility for various logic levels. Consider the 16-TSSOP package size for space-constrained designs. Verify that the ±15kV ESD rating meets the specific environmental protection requirements of the target application.

Part Context

This part belongs to the ICL3232 family of RS-232 transceivers originally developed by Intersil and now produced by Renesas. The base model typically refers to the through-hole DIP version, while the IVZ suffix indicates the lead-free, halogen-free variant in a TSSOP package. The T7A suffix specifically denotes the reel quantity and packaging style for automated assembly processes.

Replacement Considerations

ICL3232IVZ-T is a compatible alternative from the same manufacturer offering identical electrical characteristics without the specific T7A reel configuration.
