ICL3245ECA

Overview

The ICL3245ECA is a triple line transceiver manufactured by Harris Corporation, designed for RS-232 communication applications. It operates within a supply voltage range of +3V to +5.5V and supports data rates up to 1Mbps. The device features enhanced automatic powerdown functionality to minimize current consumption during idle periods. Packaged in a 28-pin Plastic Dual In-line Small Outline (SOIC) format, it integrates three drivers and three receivers on a single chip. The component is rated for operation over an extended temperature range, typically from -40°C to +85°C, ensuring reliability in industrial environments.

Feature Summary

• Triple channel configuration providing three independent drivers and receivers for simultaneous serial communication
• Enhanced automatic powerdown mechanism that significantly reduces quiescent current when the bus is inactive
• Wide single-supply voltage compatibility allowing direct interfacing with standard logic families

Applications

• Industrial control systems requiring robust RS-232 connectivity
• Portable battery-powered equipment utilizing low-power transceivers
• Multi-port serial communication interfaces in embedded systems

Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation's semiconductor assets were acquired by Intersil, which was subsequently acquired by Renesas Electronics. Ensure the part number suffix matches the specific package and temperature grade required for your design. Cross-reference with Intersil or Renesas datasheets for updated electrical specifications and pinout configurations to guarantee compatibility.

Selection Notes

Select this component when a triple-channel RS-232 solution with low standby power is required. Compare against similar parts like the MAX3237 or ICL3241 if fewer channels suffice. Consider the SOIC-28 package constraints for PCB layout. Verify that the +3V to +5.5V operating range aligns with your system's power supply rails and that the 1Mbps speed meets your baud rate requirements.

Part Context

This component belongs to the family of high-performance RS-232 transceivers originally developed by Harris Semiconductor. These devices are engineered to replace older dual-transceiver solutions, offering higher integration density. The ICL3245 series is widely recognized for its balance of performance and power efficiency in legacy and modern industrial serial communication designs.

Replacement Considerations

Potential substitutes include the ICL3245EIB (same function, different package variant) or the MAX3237ECW from Texas Instruments. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution.
