ICL3227EIAZA

Overview

The ICL3227EIAZA 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 one driver and one receiver. Key electrical specifications include a maximum output current of 35 mA, an operating supply current of 1 mA, and a propagation delay of 150 ns. It provides 15 kV ESD protection on all pins and includes a shutdown feature. The component is housed in an SSOP-16 package and is rated for industrial temperature operation from -40°C to +85°C.

Feature Summary

• Integrated RS-232 transceiver with single driver and single receiver channels
• High electrostatic discharge (ESD) protection rating of 15 kV on all pins
• Low power consumption with dedicated shutdown mode capability
• Industrial temperature range support for robust environmental operation

Applications

• RS-232 serial communication interfaces in industrial control systems
• Point-to-point data transmission links requiring high ESD immunity
• Embedded systems utilizing low-voltage microcontrollers

Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range (-40°C to +85°C) compared to commercial variants. Confirm RoHS compliance status through official documentation as requirements may vary by region. Check for end-of-life notices or obsolescence warnings directly from Renesas, as availability for legacy Intersil-branded parts can be limited. Ensure moisture sensitivity level handling procedures are followed during assembly.

Selection Notes

Select this component when a single-channel RS-232 interface is required with enhanced ESD protection. Compare against the ICL3227ECAZA if commercial temperature range suffices. Verify that the SSOP-16 package fits the PCB layout constraints. Ensure the 1 Mb/s data rate meets system timing requirements. Consider the 3 V to 5.5 V supply compatibility with the target logic levels.

Part Context

This part belongs to the ICL3227E series of RS-232 transceivers. It shares functional similarities with other single-driver devices in the family but differs in packaging and temperature ratings. The 'I' suffix denotes industrial grade, while 'C' typically indicates commercial grade. It serves as a bridge between TTL/CMOS logic levels and RS-232 voltage standards.

Replacement Considerations

Direct substitutes include the ICL3227ECAZA for commercial temperature applications. Cross-reference with MAX3227EIAZ for pin-compatible alternatives. Verify electrical parameters match before substitution.
