ICL3243EIV

Overview

The Intersil ICL3243EIV is a single-driver, five-receiver RS-232 transceiver designed for low-power applications. It operates within a supply voltage range of 3.0V to 5.5V and supports data rates up to 250kbps. The device features manual and automatic powerdown modes, reducing standby current to 1µA. It includes on-chip charge pumps requiring only four external 0.1µF capacitors. The component provides 15kV ESD protection and meets EIA/TIA-232 specifications at 3V operation.

Feature Summary

• Integrates manual and automatic powerdown functions to minimize standby power consumption
• Utilizes on-chip voltage converters with minimal external capacitance requirements
• Provides robust electrostatic discharge protection for reliable signal integrity

Applications

• Portable computing devices such as PDAs and palmtops
• Notebook and laptop computer serial communication interfaces
• Battery-powered systems requiring extended operational life

Procurement Notes

Verify the specific suffix 'EIV' against official Renesas or Intersil documentation to confirm package type and temperature grade. Ensure compatibility with existing board layouts regarding capacitor placement and pin configuration before procurement.

Selection Notes

Select this component for designs requiring a single driver and multiple receivers in a compact form factor. It serves as a drop-in replacement for legacy MAX3243 devices. Verify that the 250kbps data rate meets system timing requirements.

Part Context

This part belongs to the ICL32XX family of RS-232 transceivers. These devices are engineered for 3V to 5.5V systems, offering compatibility with both 3.3V and 5.0V logic levels while maintaining low power consumption characteristics suitable for mobile electronics.

Replacement Considerations

Publicly confirmed direct substitutes include MAX3243, SP3243, and HIN232 variants. Verify pinout compatibility and electrical parameters before substituting with these equivalent components.
