ICL3241ECAZ

Overview

The ICL3241ECAZ is a single RS-232 transceiver manufactured by Renesas Electronics, housed in a 28-pin SSOP package. It operates on a supply voltage range of 3 V to 5.5 V and supports data rates up to 250 kb/s. The device features three drivers and five receivers for full-duplex communication. It includes an integrated charge pump and offers ±15 kV ESD protection at the RS-232 pins. The component functions within a temperature range of 0°C to +70°C with a typical operating current of 1 mA.

Feature Summary

• Integrated charge pump enables operation from a single power supply without external components
• Provides ±15 kV electrostatic discharge protection on all RS-232 lines
• Includes shutdown mode to minimize standby power consumption

Applications

• Portable computers and laptops requiring serial connectivity
• Personal digital assistants (PDAs) and handheld devices
• Industrial control systems with RS-232 interfaces

Procurement Notes

Verify the specific suffix 'ECAZ' against the manufacturer's official documentation to confirm pinout compatibility and RoHS status. Ensure the SSOP-28 package dimensions match the target PCB footprint. Confirm that the commercial temperature range meets the operational requirements of the final assembly environment before procurement.

Selection Notes

Select this component when a low-power RS-232 solution is required for 3.3 V or 5 V systems. It is suitable for designs needing multiple transmit and receive channels in a compact surface-mount package. Consider alternative variants if extended industrial temperature ranges or different packaging options are necessary for the application.

Part Context

This part belongs to the ICL3241 series of RS-232 transceivers designed for portable electronics. The series focuses on reducing system power consumption while maintaining compliance with EIA/TIA-232 standards. The ECAZ designation indicates a specific tape-and-reel packaging configuration for automated assembly processes.

Replacement Considerations

Direct replacements include other members of the ICL3241 family such as ICL3241EIVZ, provided the package type matches. Verify functional equivalence regarding driver/receiver counts and ESD protection levels before substitution.
