ICL3227EIA

Overview

The ICL3227EIA is a single driver, single receiver RS-232 transceiver manufactured by Intersil. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 1 Mb/s. The device features full-duplex communication and includes an automatic shutdown function for power reduction. It provides 15 kV ESD protection on the RS-232 pins and operates within a commercial temperature range of 0°C to +70°C. The typical operating supply current is 1 mA, with a maximum output current of 35 mA. The propagation delay is specified at 150 ns. It is housed in an SSOP-16 package.

Feature Summary

• Integrated automatic shutdown circuitry reduces standby power consumption when no valid signal is detected.
• Built-in charge pumps generate required RS-232 voltage levels from low-voltage supplies without external inductors.
• High electrostatic discharge tolerance protects sensitive inputs and outputs against human body model events.

Applications

• Portable computing devices requiring low-power serial communication
• Industrial control systems with RS-232 interfaces
• Embedded systems utilizing 3V or 5V logic levels

Procurement Notes

Verify component authenticity through authorized channels due to potential availability from secondary markets. Confirm RoHS compliance status and specific manufacturing date codes prior to integration. Check for moisture sensitivity level requirements during storage and handling procedures to ensure long-term reliability.

Selection Notes

Select this component for applications requiring a single driver and receiver configuration with low power consumption. Ensure the system operates within the 3V to 5.5V supply range and requires 15kV ESD protection. Verify that the SSOP-16 package fits the board layout constraints and thermal requirements.

Part Context

This part belongs to the ICL3227E series of low-power RS-232 transceivers designed for portable electronics. It serves as a drop-in replacement for older generations of RS-232 drivers while offering improved power efficiency and integrated ESD protection suitable for modern mobile and handheld devices.

Replacement Considerations

Check datasheets for compatible alternatives such as the MAX3227 or SP3227. Verify pin compatibility, electrical specifications, and package dimensions before substitution. Ensure the replacement meets the same ESD and voltage requirements.
