ICL3232IVZ-T

Overview

The ICL3232IVZ-T is a dual RS-232 transceiver manufactured by Renesas Electronics Corporation, housed in a 16-pin TSSOP surface-mount package. It supports full-duplex communication with two drivers and two receivers, operating at data rates up to 250 kb/s. The device functions on a single power supply ranging from 3 V to 5.5 V, including standard 3.3 V and 5 V levels. It draws a typical operating current of 1 mA and withstands electrostatic discharge voltages of up to 15 kV. The component is rated for industrial temperatures between -40°C and +85°C.

Feature Summary

• Integrated charge pump circuitry eliminates the need for external capacitors in many configurations, simplifying board layout.
• Provides robust ESD protection on both driver outputs and receiver inputs to safeguard connected serial ports.
• Ensures reliable signal integrity through guaranteed output voltage swings that meet RS-232 standards under various load conditions.

Applications

• Industrial control systems requiring serial communication interfaces
• Portable battery-powered devices utilizing low-power RS-232 links
• Embedded systems connecting microcontrollers to legacy serial peripherals

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the 'IVZ' designation corresponds to the industrial temperature range and TSSOP package variant. Ensure compatibility with existing PCB footprints designed for 16-pin thin-shrink small-outline packages before finalizing procurement quantities.

Selection Notes

Select this component when a dual-channel RS-232 interface is required in a compact surface-mount form factor. It is suitable for designs needing low quiescent current and operation from a single 3V or 5V supply. Consider alternative packages like SOIC if higher pin count or different thermal characteristics are needed for the specific application constraints.

Part Context

This part belongs to the ICL3232 series of line transceivers originally developed by Intersil and now produced by Renesas. The series is widely recognized for its reliability in RS-232 applications. The IVZ suffix specifically denotes the industrial grade temperature range and the TSSOP-16 package type, distinguishing it from commercial variants or other package styles.

Replacement Considerations

The ICL3232IVZ-T7A is a verified substitute offering identical electrical specifications and functionality. Both parts share the same 16-TSSOP footprint and performance parameters, allowing for direct pin-to-pin replacement in existing designs without circuit modification.
