ICL3207IAZ

Overview

The ICL3207IAZ is a low-power RS-232 transceiver manufactured by Renesas Electronics Corporation, formerly Intersil. It integrates five drivers and three receivers in a single package, supporting full-duplex communication at data rates up to 250 kb/s. The device operates from a single power supply ranging from 3 V to 5.5 V, with a typical operating current of 1 mA. It utilizes a 24-pin SSOP (MO-150-AG) surface-mount package suitable for SMD/SMT installation. The component provides ESD protection rated at 15 kV and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates five independent drivers and three receivers for comprehensive multi-port connectivity
• Provides robust electrostatic discharge protection rated at 15 kV on all RS-232 lines
• Operates efficiently on a single 3 V to 5.5 V supply with minimal power consumption
• Supports standard RS-232 protocols including EIA-232 and TIA-232 specifications

Applications

• Industrial control systems requiring multiple serial connections
• Communication equipment utilizing RS-232 interfaces
• Embedded systems needing low-power serial transceivers
• Data acquisition modules with multi-channel serial input/output

Procurement Notes

Verify the specific manufacturer source, as Rochester Electronics may distribute this part alongside Renesas. Confirm RoHS compliance status directly with the supplier, as lead-free variants exist within the series. Check for moisture sensitivity handling requirements due to the SSOP packaging type. Ensure the ordering suffix matches the required tube or reel configuration if available through secondary markets.

Selection Notes

Select this component when designing circuits requiring five transmit and three receive channels within a compact footprint. Compare against the ICL3207EIA for potential alternative sourcing options. Consider the 250 kb/s speed limit when evaluating higher-speed interface needs. Verify that the 3 V to 5.5 V voltage range aligns with the target system's power rails.

Part Context

This device belongs to the ICL3207 series of RS-232 transceivers. It shares functional similarities with other members like the ICL3207EIA but differs in manufacturing origin and specific distribution channels. The ICL3207IAZ represents the industrial grade variant designed for broader environmental tolerance compared to commercial versions.

Replacement Considerations

The ICL3207EIA serves as a verified alternative from Rochester Electronics. Both parts share identical pinouts and electrical specifications. Verify package compatibility and ensure the replacement meets the same industrial temperature range requirements.
