ICL3227ECAZA

Overview

The ICL3227ECAZA 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 in full-duplex mode. The device features 15 kV ESD protection on all RS-232 lines and includes a shutdown function with a typical operating current of 1 mA. Packaged in an SSOP-16 format, it functions across commercial temperatures from 0°C to +70°C. Key electrical parameters include a maximum output current of 35 mA and a propagation delay of 150 ns.

Feature Summary

• Integrated 15 kV electrostatic discharge protection on transmit and receive lines
• Low power consumption enabled by automatic shutdown circuitry
• Single driver and receiver configuration for point-to-point communication

Applications

• Portable battery-powered equipment requiring low standby current
• Industrial control systems utilizing RS-232 serial interfaces
• Embedded devices needing robust ESD protection for external connectivity

Procurement Notes

Verify the specific manufacturer suffix and date code upon acquisition, as component sourcing may involve legacy inventory or authorized distributors. Confirm RoHS compliance status through official documentation provided by the supplier. Ensure storage conditions account for moisture sensitivity levels indicated in the datasheet to prevent package damage during soldering processes.

Selection Notes

Select this component when a single-channel RS-232 interface is required with integrated ESD protection. It is suitable for applications where low quiescent current is critical due to battery operation. Compare against similar models like the MAX3227CAE+ regarding pin compatibility and specific ESD ratings if alternative sourcing is necessary.

Part Context

This part belongs to the ICL3227E series of RS-232 transceivers. It represents a compact solution for serial communication in space-constrained designs. The SSOP-16 package allows for surface-mount assembly, facilitating integration into modern printed circuit boards while maintaining the performance characteristics of earlier leaded versions.

Replacement Considerations

The MAX3227CAE+ serves as a functional equivalent from Analog Devices/Maxim Integrated. Verify pinout compatibility and ensure that the ESD protection specifications meet the target application requirements before substitution.
