ICL3244EIAZ-T

Overview

The ICL3244EIAZ-T is a low-power RS-232 transceiver from the ICL3244 series, manufactured by Renesas Electronics. It integrates three drivers and five receivers in a single package, supporting full-duplex communication at data rates up to 250 kb/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 15 kV ESD protection on all pins and includes an automatic shutdown mode for power conservation. The component is housed in a 28-pin SSOP surface-mount package and is rated for industrial temperatures between -40°C and +85°C.

Feature Summary

• Integrates three independent drivers and five independent receivers for complex serial interface requirements.
• Provides robust electrostatic discharge protection rated at 15 kV across all signal pins.
• Incorporates an automatic shutdown feature to minimize power consumption during idle periods.
• Supports standard RS-232 protocols with single-ended receiver inputs.

Applications

• Industrial control systems requiring multiple serial connections
• Portable instrumentation with battery power constraints
• Data acquisition modules needing high noise immunity

Procurement Notes

Verify the suffix 'T' indicates reel packaging when sourcing. Confirm the specific voltage range and temperature grade match the design requirements. Check RoHS compliance status through official manufacturer documentation. Ensure the 28-SSOP footprint aligns with the PCB layout specifications before finalizing procurement.

Selection Notes

Select this component when three drivers and five receivers are required in a single IC. Consider the 250 kb/s speed limit for application compatibility. Evaluate the 3 V to 5.5 V supply range against system power rails. Verify that the 28-SSOP package size fits within the available board space constraints.

Part Context

This part belongs to the ICL32xxE family of CMOS RS-232 transceivers. It shares functional similarities with the ICL3244EIAZ but differs in packaging format. The 'T' suffix typically denotes tape-and-reel delivery for automated assembly processes.

Replacement Considerations

ICL3244EIAZ serves as the tube-packaged equivalent. Other members of the ICL3244 series may offer different driver/receiver counts or packages.
