ICL3232EFV-16Z-T

Overview

The ICL3232EFV-16Z-T is a dual transmitter and receiver RS-232 interface integrated circuit manufactured by Renesas Electronics. It operates within a supply voltage range of 3.0 V to 5.5 V, ensuring compatibility with standard logic levels while meeting EIA/TIA-232 and V.28/V.24 specifications. The device features an ultra-low standby current of 1 µA, facilitating power conservation in portable applications. It supports data rates up to 250 kbps and includes ±15 kV electrostatic discharge (ESD) protection on all RS-232 lines. Packaged in a TSSOP-16 format, it functions reliably across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Integrated ±15 kV ESD protection on transmit and receive lines for enhanced robustness
• Ultra-low standby current consumption of 1 µA for battery-powered efficiency
• Compliance with EIA/TIA-232 and V.28/V.24 standards at low voltages
• Extended operating temperature range suitable for industrial environments

Applications

• Portable handheld devices requiring low-power serial communication
• Industrial control systems operating in harsh environmental conditions
• Battery-operated equipment needing extended standby life
• Embedded systems interfacing with legacy RS-232 peripherals

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official Renesas documentation or authorized distributors. Ensure the component matches the exact part number to avoid confusion with similar variants like the ICL3232EIV-16Z-T. Check for end-of-life notices as some related models may have been discontinued.

Selection Notes

Select this component when dual-channel RS-232 communication is required with minimal power consumption. It is suitable for designs needing robust ESD protection without external components. Consider the TSSOP-16 package constraints for PCB layout. Verify that the 250 kbps data rate meets application requirements compared to higher-speed alternatives.

Part Context

This part belongs to the ICL3232 series of RS-232 transceivers from Renesas. It shares functional similarities with other members like the ICL3232EIV-16Z-T but differs in packaging and specific ordering suffixes. The series is designed for low-voltage operation, bridging modern microcontrollers with traditional serial interfaces.

Replacement Considerations

Direct substitutes include the ICL3232EIV-16Z-T, which offers identical electrical characteristics but may differ in packaging configuration. Cross-reference pinouts and electrical parameters carefully before substitution. Other family members like the ICL3221E provide single-driver options if fewer channels are needed.
