ICL3243ECAH-T

Overview

The ICL3243ECAH-T is an RS-232 transceiver manufactured by Intersil, operating within a supply voltage range of 3 V to 5.5 V. It features three drivers and five receivers, supporting full-duplex communication at data rates up to 250 kb/s. The device incorporates enhanced automatic powerdown functionality, reducing the typical supply current to 1 mA during idle states. It provides 15 kV electrostatic discharge (ESD) protection on all RS-232 lines. The component is housed in a 28-pin SSOP package and is rated for commercial operation temperatures between 0°C and +70°C.

Feature Summary

• Integrated enhanced automatic powerdown circuitry for reduced standby power consumption
• High ESD protection rating of 15 kV on transmit and receive lines
• Single-supply operation compatible with 3 V and 5 V logic levels

Applications

• Portable battery-powered equipment requiring low standby current
• Industrial control systems needing robust ESD immunity
• Communication modules utilizing RS-232 protocols

Procurement Notes

Verify the specific suffix 'H-T' against official manufacturer documentation to confirm tape-and-reel packaging and exact temperature grade specifications. Ensure compatibility with existing PCB footprints for the 28-pin SSOP form factor before procurement.

Selection Notes

Select this component when a combination of multiple receivers and drivers is required alongside low-power standby modes. Compare performance metrics such as data rate limits and ESD thresholds against alternative transceivers to ensure suitability for the target interface environment.

Part Context

This part belongs to the ICL3243 series of RS-232 transceivers designed for low-voltage applications. It shares functional similarities with other members of the family but is distinguished by its specific pin count and driver/receiver configuration suitable for complex serial interfaces.

Replacement Considerations

Check for direct substitutes like the ICL3243ECAZ or ICL3243CA-T. Verify that replacement parts maintain identical pinouts, voltage ranges, and thermal characteristics to ensure seamless integration without hardware modifications.
