ICL3245EIAZ-T

Overview

The ICL3245EIAZ-T is a low-power RS-232 transceiver manufactured by Renesas Electronics. It integrates three drivers and five receivers in a single SSOP-28 package, supporting full-duplex communication at data rates up to 1 Mb/s. The device operates from a single +3 V to +5.5 V supply with a typical quiescent current of 1 mA. It features enhanced automatic powerdown functionality that reduces power consumption during idle periods. The IC provides 15 kV ESD protection on all RS-232 lines and meets EIA/TIA-232-F standards for industrial applications.

Feature Summary

• Integrates three independent drivers and five receivers for complex serial interface requirements
• Features enhanced automatic powerdown mode to minimize power consumption when no signal activity is detected
• Provides robust 15 kV human body model ESD protection on transmit and receive lines

Applications

• Industrial control systems requiring multiple RS-232 connections
• Portable battery-powered equipment utilizing low standby current
• Data acquisition modules needing high ESD immunity

Procurement Notes

Verify the suffix 'T' indicates tape and reel packaging configuration. Confirm the 'EA' or 'EIAZ' designation aligns with lead-free RoHS compliance requirements. Check moisture sensitivity level handling instructions prior to soldering. Ensure the specific revision matches design specifications for pin compatibility.

Selection Notes

Select this component when three transmit and five receive channels are required within a single package. Compare against ICL3241 variants if fewer drivers are sufficient. Consider the SSOP-28 footprint constraints relative to PCB layout density. Evaluate the 1 Mbps speed limit against higher baud rate requirements of the target application.

Part Context

This part belongs to the ICL3245 family of RS-232 transceivers. It shares functional similarities with the ICL3241 but offers increased driver capacity. The 'E' grade denotes extended temperature range capabilities compared to commercial grades. It serves as a direct replacement for older Intersil designs in legacy hardware.

Replacement Considerations

ICL3245CAZ-T is a compatible alternative with similar electrical characteristics. Verify pinout compatibility before substituting with other RS-232 transceivers. Check if lower channel counts like ICL3241 suffice for simplified designs.
