ICL3224ECP

Overview

The Intersil ICL3224ECP is a single-driver, dual-receiver RS-232 transceiver designed for operation with supply voltages ranging from 3.0 V to 5.5 V. It supports data rates up to 1 Mb/s and features enhanced automatic powerdown functionality to minimize current consumption. The device operates within an industrial temperature range of -40°C to +85°C and includes ESD protection rated at ±15 kV on all pins. Packaged in a 20-pin PDIP format, it complies with EIA/TIA-232 and V.24/V.28 standards.

Feature Summary

• Enhanced automatic powerdown circuitry reduces operating current significantly during idle periods.
• Integrated charge pump generates required voltage swings without external components.
• Robust electrostatic discharge protection ensures reliability across all signal interfaces.

Applications

• Industrial communication systems requiring low-power serial data transmission
• Portable battery-operated equipment utilizing RS-232 connectivity
• Embedded control units interfacing with modems or terminal adapters

Procurement Notes

Verify the specific suffix against official Renesas/Intersil documentation to confirm package type and temperature grade. Confirm end-of-life status as distribution channels may vary. Ensure compliance with export restrictions if applicable to the target region. Cross-reference the manufacturer part number directly with the datasheet revision history.

Selection Notes

Select this component when a single driver and two receivers are sufficient for the design. Compare operating current specifications against similar models like the ICL3225ECPZ if through-hole packaging is not strictly required. Verify that the 1 Mbps data rate meets system timing requirements. Check compatibility with existing decoupling capacitor values specified in the application notes.

Part Context

This device belongs to the ICL32XXE family of RS-232 transceivers manufactured by Intersil, now part of Renesas Electronics. The series is characterized by low power consumption and high ESD tolerance. It serves as a legacy interface solution for converting TTL/CMOS logic levels to RS-232 signals in compact electronic designs.

Replacement Considerations

The ICL3224ECPZ is a pin-compatible alternative available in SSOP-20 packaging. Other family members such as the ICL3225ECP offer similar electrical characteristics but may differ in package dimensions or specific thermal ratings.
