ICL3232ECV-20ZT

Overview

The ICL3232ECV-20ZT is a low-power RS-232 transceiver manufactured by Renesas Electronics Corporation, belonging to the ICL3232 series. It operates on a single power supply ranging from 3.0 V to 5.5 V and supports data rates up to 500 kb/s. The device integrates two drivers and two receivers in a TSSOP-20 surface-mount package. Key electrical specifications include a maximum supply voltage of 5.5 V, a minimum of 3 V, and an operating supply current of 1 mA. It provides ±15 kV electrostatic discharge (ESD) protection on RS-232 pins and functions within a temperature range of 0°C to +70°C.

Feature Summary

• Integrated charge pump eliminates the need for external dual-voltage supplies
• Provides ±15 kV ESD protection on RS-232 input and output pins
• Low standby power consumption with automatic shutdown capability
• Compatible with TTL and CMOS logic levels

Applications

• Portable battery-powered equipment requiring low power consumption
• Laptop computers and notebook PCs
• Industrial control systems utilizing RS-232 communication
• Handheld terminals and mobile devices

Procurement Notes

Verify the suffix 'ZT' indicates tape-and-reel packaging distinct from the tube-packaged 'Z' variant. Confirm RoHS compliance status through official documentation. Check for end-of-life notices as the base model may be discontinued. Ensure moisture sensitivity level requirements are met during storage and handling procedures.

Selection Notes

Select this component when a dual-driver and dual-receiver configuration is required for RS-232 interfaces. It serves as a direct replacement for older Intersil models like the ICL232. Consider the TSSOP-20 package size constraints and the 500 kb/s data rate limit. Verify that the 3.0 V to 5.5 V supply range matches the system design requirements.

Part Context

This part belongs to the ICL32xxE family of low-power RS-232 transceivers designed for 3V to 5.5V systems. The series offers pin-compatible upgrades to legacy 5V devices, providing significant power savings. The ICL3232 variant specifically provides two drivers and two receivers, making it suitable for full-duplex communication applications in space-constrained designs.

Replacement Considerations

Publicly confirmed substitutes include the ICL3232ECAZ-T and ICL3232EIV-16Z-T. Verify pin compatibility and package dimensions before substitution. Ensure the alternative part meets the same 500 kb/s data rate and ESD protection specifications.
