ICL3232ECV-16Z-T7A

Overview

The ICL3232ECV-16Z-T7A is a dual RS-232 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3.0 V to 5.5 V and supports data rates up to 250 kbps. The device features two drivers and two receivers, providing full-duplex communication capabilities. It incorporates ±15 kV electrostatic discharge (ESD) protection on all RS-232 pins, compliant with IEC 61000-4-2 standards. The component is housed in a 16-pin TSSOP package and is designed for low-power applications, maintaining a typical operating supply current of 1 mA.

Feature Summary

• Integrated ±15 kV ESD protection on RS-232 I/O pins for enhanced reliability
• Low power consumption with 1 mA typical operating current
• Full compatibility with 3.0 V to 5.5 V single-supply systems

Applications

• Portable equipment requiring low-power serial communication
• Industrial control systems with RS-232 interfaces
• Embedded systems utilizing 3.3 V or 5 V logic levels

Procurement Notes

Verify the specific suffix 'T7A' against official Renesas documentation to confirm tape-and-reel packaging specifications. Ensure the part number matches the exact electrical characteristics required for the target application, as suffixes may indicate variations in packaging or temperature ranges. Cross-reference with authorized distributors to confirm availability and authenticity.

Selection Notes

Select this component when a dual-channel RS-232 interface is needed with robust ESD protection and low power consumption. It serves as a direct replacement for legacy devices like the ICL232 in modern 3.3 V and 5 V systems. Consider the 16-pin TSSOP package constraints during PCB layout design to ensure adequate spacing and thermal management.

Part Context

This part belongs to the ICL32xxE series of RS-232 transceivers from Renesas. The series is known for meeting EIA/TIA-232 and V.28/V.24 specifications even at lower supply voltages. The ICL3232 variant specifically provides two drivers and two receivers, making it suitable for applications requiring bidirectional data transfer without the need for additional switching components.

Replacement Considerations

The ICL3232EIV-16Z-T is a pin-compatible alternative within the same family. Verify that the substitute maintains the same data rate and ESD protection levels. Check if the replacement offers any improvements in power consumption or package type that might benefit the specific design.
