ICL3232ECBN

Overview

The ICL3232ECBN is a dual RS-232 transceiver manufactured by Intersil, designed for full-duplex data communication. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 250 kb/s. The device integrates two drivers and two receivers in a single package. Key electrical specifications include a maximum operating temperature of +70°C and an ESD protection rating of 15 kV. It features a low quiescent current of 1 mA and utilizes a SOIC-16 surface-mount package.

Feature Summary

• Provides full-duplex RS-232 signal conversion between TTL/CMOS logic levels and RS-232 voltages
• Integrates robust electrostatic discharge (ESD) protection on all RS-232 lines
• Operates efficiently with low power consumption suitable for battery-powered applications

Applications

• Industrial control systems requiring reliable serial communication
• Embedded devices interfacing with modems or barcode scanners
• Point-of-sale terminals and medical equipment

Procurement Notes

Verify the exact suffix against official Renesas/Intersil documentation to confirm pinout compatibility and thermal ratings. Confirm moisture sensitivity level handling requirements during assembly. Check for end-of-life status as older Intersil parts may have limited availability from authorized distributors.

Selection Notes

Select this component when a dual-channel RS-232 interface is required with moderate data rates. Ensure the application environment stays within the commercial temperature range of 0°C to +70°C. Verify that the PCB layout accommodates the external charge pump capacitors necessary for operation.

Part Context

This part belongs to the ICL3232 family of RS-232 transceivers. It shares functional similarities with other variants like the ICL3232IBNZ but differs in package type and specific industrial/commercial temperature grading. The 'EC' designation typically indicates a commercial grade variant in a specific surface-mount footprint.

Replacement Considerations

Direct replacements include ICL3232IBNZ for SOIC-16 packages or ICL3232CVZ for TSSOP-16 packages. Verify that substitute parts match the required temperature range and pin configuration before integration.
