ICL3244ECA

Overview

The ICL3244ECA is a full RS-232 transceiver manufactured by Harris Corporation, designed for data communication applications. It integrates three drivers and five receivers within a single package, supporting the standard RS-232 protocol. The device operates on a single power supply ranging from +3V to +5.5V, featuring low current consumption of approximately 1 microampere in shutdown mode. It supports data rates up to 250kbps and includes enhanced automatic shutdown features to reduce power usage during idle periods. The component provides robust 15kV ESD protection and functions reliably within an operating temperature range of 0°C to 70°C.

Feature Summary

• Integrates three drivers and five receivers for comprehensive RS-232 signal conversion
• Features enhanced automatic shutdown circuitry to minimize power consumption during idle states
• Provides high electrostatic discharge protection rated at 15kV for improved reliability
• Operates efficiently on a single +3V to +5.5V power supply with ultra-low standby current

Applications

• Portable battery-powered devices requiring low-power serial communication
• Industrial control systems utilizing RS-232 interfaces
• Embedded systems needing reliable data transmission with ESD protection

Procurement Notes

Verify the specific suffix and package type when sourcing, as availability may vary due to the component's obsolete status. Confirm that the supplier provides original manufacturer documentation or certified equivalents. Ensure the operating temperature range meets your application requirements, as industrial variants may differ. Check for RoHS compliance if required by your manufacturing standards, noting that older Harris Corporation parts may not meet current environmental regulations.

Selection Notes

Select this component when a full RS-232 transceiver with multiple receivers is needed for low-voltage applications. The ICL3244ECA is suitable for designs prioritizing power efficiency through its automatic shutdown feature. Consider the 28-SSOP package for surface-mount assembly constraints. Evaluate the 15kV ESD protection level against your environment's static risks. This part is appropriate for legacy system maintenance or new designs compatible with standard RS-232 signaling levels.

Part Context

The ICL3244ECA belongs to the ICL324x series of RS-232 transceivers developed by Harris Corporation. This series is known for combining driver and receiver functionalities in a compact form factor. The ICL3244 variant specifically offers three drivers and five receivers, distinguishing it from other members like the ICL3243 or ICL3245 which may have different channel counts. It represents a solution for integrating serial communication capabilities into space-constrained electronic systems.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Due to the obsolete status of the ICL3244ECA, alternative components should be evaluated based on pin compatibility, electrical specifications, and functional equivalence rather than direct cross-reference lists.
