ICL3223IVZ-T

Overview

The ICL3223IVZ-T is a dual RS-232 transceiver manufactured by Renesas Electronics, belonging to the ICL3223 series. It operates within a supply voltage range of 3 V to 5.5 V, supporting both 3.3 V and 5 V logic systems. The device provides full-duplex communication with two drivers and two receivers, achieving data rates up to 250 kb/s. Key electrical specifications include a maximum operating current of 1 mA and ESD protection rated at 15 kV. It functions reliably across an industrial temperature range from -40 °C to +85 °C. The component is housed in a TSSOP-20 package designed for surface mount technology.

Feature Summary

• Integrates automatic power-down circuitry to minimize energy consumption during idle periods
• Provides robust electrostatic discharge protection on all pins to ensure signal integrity
• Supports single-ended receiver input signals for standard RS-232 compatibility

Applications

• Industrial control systems requiring reliable serial communication
• Portable battery-powered equipment utilizing low-power interface solutions
• Modems and fax machines implementing RS-232 protocols

Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging distinct from the tube variant. Confirm moisture sensitivity level handling requirements prior to assembly. Ensure the specific revision matches design documentation. Cross-reference manufacturer datasheets for exact pinout definitions. Validate RoHS compliance status through official certification records.

Selection Notes

Select this component when designing circuits requiring dual-channel RS-232 connectivity with minimal power draw. The wide supply voltage range accommodates various logic levels without external level shifters. Consider the TSSOP-20 footprint for space-constrained printed circuit board layouts. Verify thermal performance meets system requirements within the specified industrial temperature limits.

Part Context

This part belongs to the ICL3223 family of RS-232 transceivers produced by Renesas Electronics. The series is known for combining high performance with low power consumption features suitable for modern embedded applications. The 'IVZ' designation typically denotes the industrial temperature grade and specific packaging configuration offered by the manufacturer.

Replacement Considerations

Check for direct substitutes such as the ICL3223IEZA or ICL3223IVZA if reel packaging is not required. Verify functional equivalence regarding driver/receiver counts and voltage specifications before substitution.
