ICL3223EIAZ-T

Overview

The ICL3223EIAZ-T is a single-driver, dual-receiver RS-232 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 500 kb/s. The device features an automatic shutdown mechanism that reduces operating current to 1 mA in standby mode. It is housed in a 20-pin SSOP package and includes ESD protection for the RS-232 interface pins. The component complies with EIA/TIA-232 and V.28/V.24 specifications.

Feature Summary

• Automatic power-down circuitry activates when no valid signal is detected on receiver inputs, significantly reducing standby power consumption.
• Integrated charge pumps generate required RS-232 voltage levels from a single low-voltage supply without external transformers.
• Input protection circuits safeguard receiver pins against electrostatic discharge events.

Applications

• Portable computing devices requiring low-power serial communication interfaces
• Industrial control systems utilizing RS-232 protocols
• Embedded systems with limited power budgets

Procurement Notes

Verify the specific suffix 'EIAZ' against official Renesas documentation to confirm RoHS compliance status and lead-free manufacturing details. Confirm the SSOP-20 package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a single transmitter and two receivers are required for RS-232 connectivity. Ensure the application environment remains within the -40°C to +85°C operating temperature range. Verify that the 500 kb/s maximum data rate meets the system's transmission speed requirements.

Part Context

This part belongs to the ICL3223 series of intelligent RS-232 transceivers. It is designed as a drop-in replacement for legacy components while offering improved power efficiency through automatic shutdown features. The device integrates all necessary charge pump capacitors internally or requires minimal external capacitance.

Replacement Considerations

Cross-reference with MAX3223EUP for functional compatibility. Verify pinout alignment and electrical parameter equivalence before substituting in existing designs.
