ICL3245EIAZ

Overview

The ICL3245EIAZ is a low-power RS-232 transceiver manufactured by Renesas Electronics Corporation, designed for full-duplex communication. It integrates three drivers and five receivers within a single package, supporting data rates up to 1 Mb/s. The device operates on a single power supply ranging from 3 V to 5.5 V, with a typical operating current of 1 mA. It features enhanced automatic powerdown functionality that reduces standby current significantly. The component provides 15 kV electrostatic discharge (ESD) protection on all RS-232 lines and meets EIA/TIA-232-F standards. It is housed in a 28-pin SSOP package suitable for surface mount applications.

Feature Summary

• Integrates three independent drivers and five independent receivers for versatile serial communication configurations.
• Features enhanced automatic powerdown mode that minimizes power consumption during idle periods.
• Provides robust 15 kV human body model ESD protection across all RS-232 signal lines.

Applications

• Portable battery-powered equipment requiring low standby current
• Industrial control systems utilizing RS-232 interfaces
• Modem and fax machine communication circuits

Procurement Notes

Verify the specific suffix 'EIAZ' corresponds to the lead-free RoHS-compliant version in the 28-SSOP package. Confirm the manufacturer source is Renesas Electronics or authorized Intersil legacy channels. Check moisture sensitivity level requirements for storage and handling prior to assembly.

Selection Notes

Select this component when a combination of three transmit and five receive channels is required in a compact form factor. It is suitable for designs needing high ESD immunity without external protection components. Consider the 1 Mb/s speed limit and 3 V to 5.5 V supply range against system voltage constraints.

Part Context

This part belongs to the ICL3245 family of RS-232 transceivers, which are widely used in legacy serial communication interfaces. The 'E' designation typically indicates an extended temperature range variant compared to commercial grade parts. The 'IAZ' suffix specifies the tape and reel packaging option and lead-free composition.

Replacement Considerations

ICL3245EIAZ-T: Same electrical specifications but supplied in cut tape or reel format instead of tube packaging. Verify if the specific quantity per unit matches the project requirement.
