ICL232CBES2535

Overview

The ICL232CBES2535 is a dual driver and receiver line transceiver manufactured by Harris Corporation, designed for EIA-232-E communication standards. It integrates two drivers and two receivers within a single CMOS functional unit. The device utilizes a 16-pin SSOP (Shrink Small Outline Package) with a plastic/epoxy body. Key electrical characteristics include Schmitt trigger input characteristics to enhance noise immunity and inverted output polarity. The component operates within a temperature range of -40 °C to 70 °C and supports a minimum output voltage swing of 10 V. It is not RoHS compliant and carries an ECCN code of EAR99.

Feature Summary

• Integrates dual drivers and dual receivers for complete RS-232 signal conversion in a compact form factor.
• Features Schmitt trigger inputs on the receiver side to provide improved noise filtering and signal integrity.
• CMOS technology implementation ensures low power consumption while maintaining compatibility with standard logic levels.

Applications

• Serial communication interfaces adhering to EIA-232-E, V.24, and V.28 standards.
• Industrial control systems requiring robust signal transmission over short distances.
• Embedded data acquisition modules utilizing CMOS logic families.

Procurement Notes

Verify the specific suffix 'ES2535' against manufacturer documentation to confirm batch-specific revisions or testing requirements. Confirm that the non-RoHS status aligns with current regulatory constraints for the intended deployment region. Ensure the SSOP16 footprint matches the target PCB design guidelines precisely.

Selection Notes

Select this component when a dual-channel RS-232 transceiver with Schmitt trigger inputs is required for CMOS-based designs. Consider the 70 °C maximum operating temperature limit for environmental suitability. Verify package availability in SSOP format if surface mount assembly is mandated for the production line.

Part Context

This part belongs to the ICL232 family of line transceivers produced by Harris Corporation, which was later acquired by Intersil and subsequently Renesas Electronics. The ICL232 series is widely recognized as a standard solution for converting TTL/CMOS levels to RS-232 voltages. The specific designation indicates a commercial grade variant packaged in SSOP.

Replacement Considerations

Direct replacements may include the MAX232 or SP232E series from Maxim Integrated or Sipex, respectively. These alternatives offer similar pinouts and functionality but may differ in supply voltage ranges or package options. Verify electrical compatibility before substitution.
