ICL3232EIV-16T

Overview

The ICL3232EIV-16T is a dual RS-232 transceiver manufactured by Renesas Electronics Corporation, designed for serial communication applications. 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 ESD protection on all RS-232 lines and meets EIA/TIA-232 and V.28/V.24 specifications. Packaged in a TSSOP-16 surface-mount format, it functions across an industrial temperature range from -40°C to +85°C with a typical operating current of 1 µA.

Feature Summary

• Integrated high electrostatic discharge (ESD) protection rated at ±15 kV on transmit and receive lines.
• Capable of reliable operation with standard single-supply voltages between 3.0 V and 5.5 V.
• Provides full-duplex signal transmission and reception without requiring external inverters.

Applications

• Industrial control systems requiring robust serial communication interfaces.
• Portable battery-powered equipment utilizing low-power RS-232 connectivity.
• Embedded systems interfacing with modems or barcode scanners.

Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for TSSOP-16 components. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Cross-reference part numbers with authorized distributors to avoid counterfeit inventory.

Selection Notes

Select this component when dual-channel RS-232 communication is required in space-constrained designs. It is suitable for applications needing moderate data speeds up to 250 kbps. Consider alternative variants if shutdown functionality or different pinout configurations are necessary. Verify that the 3.0 V minimum supply voltage aligns with the system power architecture.

Part Context

This device belongs to the ICL3232 family of RS-232 transceivers, which are widely used in legacy serial communication standards. The series offers various packaging options including SOIC and SSOP formats. It serves as a bridge between TTL/CMOS logic levels and RS-232 voltage swings, facilitating data exchange between microcontrollers and peripheral devices.

Replacement Considerations

Direct substitutes include ICL3232EIV-16Z and MAX3232EIDR. Verify pin compatibility and electrical specifications before substitution. Check for equivalent ESD protection ratings and operating temperature ranges. Ensure the replacement supports the same data rate and supply voltage requirements.
