ICL3222CA

Overview

The ICL3222CA is a triple line transceiver manufactured by Harris Corporation, classified under analog mixed-signal ICs. It features three functional units and utilizes a PDSO28 package with 28 terminals. The device operates within a temperature range of 0.0°C to 70°C. It supports EIA-232, TIA-232, V.24, and V.28 interface standards. Key electrical parameters include a maximum output low current of 0.0016 Amp and an input characteristic based on Schmitt trigger logic. The component is RoHS compliant and housed in plastic epoxy material.

Applications

• EIA-232/TIA-232 serial communication interfaces
• V.24/V.28 data transmission systems
• Industrial control equipment requiring triple line transceivers

Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successor entities such as Intersil or Renesas, as corporate acquisitions often transfer product lines. Confirm the specific package marking matches the PDSO28 physical dimensions and terminal configuration. Ensure the component meets the required environmental operating temperatures between 0.0°C and 70°C for the intended application environment.

Selection Notes

Select this component when a triple channel RS-232 solution is required in a compact SSOP-28 form factor. Verify compatibility with Schmitt trigger inputs for noise immunity in noisy industrial environments. Check that the 28-terminal PDSO28 footprint aligns with existing PCB layouts. Ensure the voltage swing capabilities meet the system's signal integrity requirements for reliable data transmission over standard serial links.

Part Context

This part belongs to the family of triple line transceivers designed for serial communication applications. It serves as a bridge between low-voltage logic circuits and RS-232 compatible devices. The device integrates drivers and receivers for three channels, consolidating functionality typically requiring multiple discrete components into a single integrated circuit package.

Replacement Considerations

Cross-reference with other triple line transceivers in the PDSO28 or SSOP-28 package. Verify pin-to-pin compatibility with equivalent parts from Intersil or Renesas if Harris branding is discontinued. Ensure electrical specifications for drive strength and input thresholds match the original design requirements.
