ICL3227ECAZA-T

Overview

The ICL3227ECAZA-T is a single-driver, single-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 1 Mb/s. The device features full-duplex communication with enhanced automatic powerdown functionality, reducing operating supply current to approximately 1 mA. It includes shutdown control for low-power applications and provides ±15 kV ESD protection on all RS-232 lines. Packaged in an SSOP-16 format, it meets EIA/TIA-232 standards.

Feature Summary

• Integrated automatic powerdown circuitry reduces quiescent current during idle periods
• Provides robust electrostatic discharge protection rated at ±15 kV on interface pins
• Supports standard RS-232 signaling levels with single-supply operation

Applications

• Industrial equipment serial communication ports
• Portable battery-powered devices requiring low standby current
• Computer peripheral interfaces adhering to EIA/TIA-232 standards

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration distinct from tube variants. Confirm RoHS compliance status through official manufacturer documentation as regulatory details may vary by production batch. Ensure sourcing channels provide valid traceability records for this discontinued or end-of-life component series.

Selection Notes

Select this component when designing systems requiring minimal power consumption in standby modes alongside standard RS-232 connectivity. The single-driver architecture suits point-to-point links where only one transmit line is necessary. Verify that the SSOP-16 package footprint aligns with existing PCB layout constraints and thermal management requirements.

Part Context

This part belongs to the ICL3227E family of low-power RS-232 transceivers. It shares core electrical specifications with other members like the ICL3227ECAZA but differs in packaging quantity and handling format due to the reel designation. The series emphasizes energy efficiency for portable applications while maintaining compatibility with legacy serial protocols.

Replacement Considerations

Direct substitutes include the ICL3227ECAZA for identical electrical performance in tube packaging. Cross-reference with MAX3227 or SP3227 equivalents if pin-compatible alternatives are required, ensuring voltage ranges and ESD ratings match the original design specifications.
