ICL3223EIVZ-T

Overview

The ICL3223EIVZ-T is a dual-driver, dual-receiver RS-232 transceiver manufactured by Renesas Electronics. 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 features full-duplex communication and includes an automatic power-down function to reduce standby current to 1 mA. It provides ±15 kV electrostatic discharge (ESD) protection on transmitter outputs and receiver inputs. The component is housed in a TSSOP-20 surface-mount package and functions across an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Automatic power-down functionality that reduces standby power consumption when the cable is removed or peripheral is off
• Integrated charge pumps enabling operation with small external capacitors for board space savings
• Enhanced ESD protection rated at ±15 kV air-gap discharge on all driver and receiver pins

Applications

• Portable digital assistants (PDAs)
• Notebook and laptop computers
• Systems requiring low operational and standby power consumption

Procurement Notes

Verify the suffix 'T' indicates reel packaging configuration. Confirm RoHS compliance status through official datasheets. Ensure moisture sensitivity level requirements are met during storage and handling procedures prior to assembly.

Selection Notes

Select this component for applications requiring true 3V to 5.5V RS-232 operation with minimal standby current. The automatic shutdown feature distinguishes it from manual shutdown variants. Verify pinout compatibility if replacing older Intersil versions due to potential package variations.

Part Context

This part belongs to the ICL32xx family of RS-232 transceivers designed for low-power portable electronics. It shares architectural similarities with the MAX3223E but is produced under the Renesas/Intersil brand lineage. The device targets systems where battery life and physical footprint are critical constraints.

Replacement Considerations

MAX3223EUP-TG1Z serves as a functional equivalent with identical AutoShutdown capabilities. Cross-reference pinouts carefully as package types may differ between manufacturers despite electrical equivalence.
