ICL232CBETS2497

Overview

The ICL232CBETS2497 is a single-function RS-232 line transceiver manufactured by Harris Corporation. It integrates two drivers and two receivers within a CMOS-based architecture, housed in a 16-pin SSOP package. The device operates on a single power supply ranging from 3.0V to 5.5V, ensuring compatibility with both 3.3V and 5.0V logic systems. It features internal charge pumps for generating the required RS-232 voltage levels without external transformers. The component supports data rates exceeding 250kbps and includes ±15kV ESD protection on all RS-232 pins, meeting IEC61000-4-2 standards.

Feature Summary

• Integrates dual drivers and dual receivers for bidirectional serial communication
• Includes internal charge pumps eliminating the need for external transformers
• Provides ±15kV electrostatic discharge protection on RS-232 interface pins
• Operates across a wide single-supply voltage range of 3.0V to 5.5V

Applications

• Portable battery-powered equipment requiring low standby current
• Laptop computers and notebook PCs
• Handheld terminals and industrial control devices
• Systems interfacing 3.3V or 5.0V microcontrollers with RS-232 peripherals

Procurement Notes

Verify the specific suffix 'ETS2497' against official Harris documentation to confirm exact packaging, tape-and-reel specifications, and environmental compliance status. Ensure the source document explicitly identifies this part as an active or obsolete component before procurement planning. Cross-reference the manufacturer's official datasheet for any lot traceability requirements.

Selection Notes

Select this component when designing systems that require pin-compatible upgrades to older MAX221E or MAX242E devices while reducing power consumption. It is suitable for applications needing reliable communication at speeds above 250kbps with minimal external capacitance. Consider its low quiescent current and automatic power-down features for battery-operated designs where space constraints limit capacitor size.

Part Context

This part belongs to the ICL32xxE series of RS-232 transceivers, which are designed as low-power alternatives to standard 5V devices. The series maintains electrical compatibility with legacy components like the HIN232E and ICL232 while offering improved performance in terms of power efficiency and ESD robustness. It represents Harris Corporation's solution for modernizing serial interfaces in compact electronic systems.

Replacement Considerations

Publicly confirmed direct substitutes include the MAX3221E, MAX3222E, and their variants. These components offer similar functionality and pinout configurations. Verify that the replacement part meets the specific voltage and temperature requirements of the original design before implementation.
