ICL3238EIAZ

Overview

The ICL3238EIAZ is a CMOS RS-232 transceiver manufactured by Renesas Electronics, housed in a 28-pin SSOP surface-mount package. It operates within a supply voltage range of 3V to 5.5V and supports full-duplex communication at data rates up to 250 kb/s. The device integrates five drivers and three receivers, featuring low power consumption with an operating current of 1 mA. It includes a shutdown mode for extended battery life and provides 15 kV ESD protection on all inputs and outputs. The component functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates five independent drivers and three receivers for multichannel serial communication
• Features integrated charge pumps requiring only external 0.1 µF capacitors
• Includes logic shutdown control to minimize power consumption during idle periods
• Provides robust 15 kV electrostatic discharge protection on signal pins

Applications

• Industrial equipment requiring reliable serial data transmission
• Portable battery-powered instruments utilizing low-power interface solutions
• Communication systems needing multiple RS-232 channels in compact form factors

Procurement Notes

Verify the specific suffix 'IAZ' confirms the SSOP-28 package and lead-free RoHS compliance when sourcing. Confirm that the manufacturer designation aligns with Renesas Electronics or authorized Intersil legacy lines to ensure authenticity. Check datasheet revisions for any pinout consistency updates relative to previous generations.

Selection Notes

Select this component when designing systems requiring five transmit and three receive channels within a single IC. It is suitable for applications demanding low standby current through shutdown functionality. Ensure the design accommodates the required external 0.1 µf capacitors for the internal charge pump operation.
