ICL3244CV

Overview

The ICL3244CV is a triple line transceiver manufactured by Intersil, designed for RS-232 communication. It operates within a supply voltage range of 3.0V to 5.5V and supports data rates up to 250kbps. The device features three drivers and three receivers housed in a 28-pin SSOP package (MO-150AH). It includes on-chip charge pumps requiring only four external 0.1µF capacitors. The component meets EIA/TIA-232 and V.28/V.24 specifications at 3V operation.

Feature Summary

• Integrated manual and automatic powerdown functions to minimize standby current
• On-chip voltage converters eliminate the need for external dual-voltage supplies
• Guaranteed mouse driveability for serial port applications
• Receiver hysteresis provides noise immunity

Applications

• Personal Digital Assistants (PDAs)
• Palmtop computers
• Notebook and laptop computers

Procurement Notes

Verify the specific suffix 'CV' against official Intersil documentation to confirm temperature grade and RoHS compliance status. Ensure the ordering information matches the exact pinout and electrical characteristics required for the target design. Cross-reference with the manufacturer's current datasheet revision to avoid obsolete part numbers.

Selection Notes

Select this component when a triple-channel RS-232 interface is required for low-power portable systems. It serves as a drop-in replacement for MAXIM MAX3241 devices. Consider the 28-pin SSOP package constraints and verify that the application environment stays within the specified operating temperature range.

Part Context

This device belongs to the Intersil ICL32XX family of RS-232 transceivers. These parts are engineered for battery-powered equipment where low operational and standby power consumption is critical. The family offers compatibility with 3.3V and 5.0V systems while maintaining full RS-232 performance.

Replacement Considerations

Publicly confirmed substitutes include Maxim MAX3241. Verify pin compatibility and electrical parameter alignment before substitution.
