ICL3241ECB

Overview

The ICL3241ECB is a dual RS-232 transceiver manufactured by Renesas Electronics, designed for full-duplex data communication. It integrates two drivers and two receivers within a single package, supporting data rates up to 120 kb/s. The device operates on a single power supply ranging from 3 V to 5.5 V, with a typical operating current of 1 mA. It features low standby current via an integrated shutdown mode and provides 15 kV ESD protection on RS-232 lines. The component utilizes SSOP-28 packaging and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrates dual drivers and receivers for full-duplex RS-232 communication
• Includes shutdown mode for significant power reduction in standby applications
• Provides robust 15 kV electrostatic discharge protection on signal lines

Applications

• Industrial control systems requiring serial communication interfaces
• Portable battery-powered equipment needing low-power operation
• Modems and fax machines utilizing standard RS-232 protocols

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm pinout compatibility and thermal specifications. Ensure the procurement channel sources components directly from authorized distributors to guarantee authenticity. Check for RoHS compliance status relevant to the manufacturing date code. Confirm moisture sensitivity level handling requirements prior to soldering processes.

Selection Notes

Select this component when a dual-channel RS-232 interface is required within space-constrained designs. It serves as a suitable alternative to legacy Intersil parts for manufacturers migrating to the Renesas portfolio. Consider the SSOP-28 footprint during PCB layout planning. Evaluate the 120 kb/s speed limit against application timing requirements before finalizing the design.

Part Context

This part belongs to the ICL3241 series of RS-232 transceivers, which are widely used in legacy and modern embedded systems. The series maintains compatibility with earlier Intersil designs, facilitating drop-in replacements. Renesas continues to support these components for industrial and consumer electronics markets requiring reliable serial connectivity.

Replacement Considerations

The ICL3241ECAZ is a verified equivalent variant offering identical electrical performance in an SSOP-28 package. Verify pin-to-pin compatibility before substitution. Other family members like the MAX3241 may require voltage translation adjustments.
