ICL3244IV

Overview

The Intersil ICL3244IV is a low-power RS-232 transceiver designed for portable applications. It operates on a single 3.0V to 5.5V supply and includes an internal charge pump. The device features three drivers and five receivers, supporting data rates up to 250kbps. It provides ±15kV ESD protection on all RS-232 lines. The component complies with EIA/TIA-232 and V.28/V.24 standards. It offers manual shutdown control to reduce power consumption in battery-operated systems.

Feature Summary

Integrated charge pump enables operation from a single low-voltage supply without external inductors.
Includes dedicated receiver for modem control signals to support system wake-up functionality.
Provides robust electrostatic discharge protection on input and output pins.

Applications

Portable computers and laptops requiring full serial port implementation
Personal digital assistants (PDAs) and handheld devices
Battery-powered industrial equipment

Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm package type and temperature range. Ensure the ordering code matches the required RoHS compliance status. Confirm availability of the TSSOP-28 package variant if surface mount assembly is specified for the design.

Selection Notes

Select this component when a complete RS-232 interface with multiple control lines is needed in a space-constrained environment. The inclusion of a dedicated modem receiver simplifies hardware design for flow control. Verify that the 250kbps speed meets the application requirements compared to higher-speed alternatives.

Part Context

This part belongs to the ICL32xE series of low-power RS-232 transceivers. The series is characterized by its ability to operate at lower voltages while maintaining standard RS-232 signal levels through internal voltage conversion.

Replacement Considerations

ICL3241EIVZ: Offers similar functionality but with different driver/receiver counts. ICL3244EIAZ-T: Identical electrical specifications with SSOP-28 packaging.
