ICL3245EIA

Overview

The ICL3245EIA is a low-power RS-232 transceiver manufactured by Renesas Electronics. It integrates three drivers and five receivers in a single package, supporting full-duplex communication at data rates up to 1 Mb/s. The device operates from a single 3 V to 5.5 V power supply with a typical quiescent current of 1 mA. It features 15 kV ESD protection on all pins and utilizes external capacitors for charge pump voltage generation. The component is housed in an SSOP-28 surface-mount package and supports the RS-232 protocol.

Feature Summary

• Integrates three independent drivers and five independent receivers for complex serial interface requirements.
• Provides robust electrostatic discharge protection rated at 15 kV across all signal pins.
• Operates efficiently on a single low-voltage power supply ranging from 3 V to 5.5 V.
• Supports high-speed data transmission with a maximum rate of 1 Mb/s.

Applications

• Industrial control systems requiring reliable serial communication links.
• Portable battery-powered equipment utilizing low-power RS-232 interfaces.
• Modems and other telecommunications devices needing full-duplex data transfer.
• Embedded systems interfacing with PC serial ports or terminal equipment.

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm pinout compatibility and electrical characteristics. Ensure the procurement channel provides valid traceability for moisture sensitivity handling. Confirm RoHS compliance status matches project requirements before finalizing orders.

Selection Notes

Select this component when three transmit and five receive channels are required within a single IC footprint. Consider the SSOP-28 package dimensions for PCB layout constraints. Verify that the system power supply remains within the 3 V to 5.5 V range to ensure proper operation of the internal charge pumps.

Part Context

This part belongs to the ICL3245E series of RS-232 transceivers designed for low-power applications. It serves as a bridge between microprocessor logic levels and RS-232 voltage standards. The series is widely used in legacy interface designs where multiple serial lines are necessary.

Replacement Considerations

Check for direct pin-compatible alternatives such as the MAX3245 or SP3245. Verify that substitute components maintain the same driver and receiver counts along with comparable ESD protection ratings.
