ICL3232CPZ

Overview

The ICL3232CPZ is a dual driver and receiver transceiver designed for RS-232 communication applications. It operates from a single +5V supply using external charge pumps to generate the necessary positive and negative voltages required for RS-232 signaling levels. The device features two drivers and two receivers, providing full duplex communication capability. It includes flow control inputs for enhanced data management and offers low power consumption characteristics suitable for battery-operated systems. The component is housed in a standard 16-pin plastic DIP package.

Feature Summary

• Single +5V supply operation with integrated charge pump circuitry
• Dual driver and dual receiver configuration for full duplex communication
• Flow control inputs for managing data transmission sequences

Applications

• RS-232 serial communication interfaces
• Modem connections
• Portable instruments requiring low power consumption

Procurement Notes

Verify the specific suffix 'CPZ' against manufacturer documentation to confirm package type and lead-free status. Ensure compatibility with existing board layout regarding charge pump capacitor requirements. Confirm voltage levels match system specifications before integration.

Selection Notes

Select this component when a dual channel RS-232 interface is required with single-supply operation. Consider the pin count and package size relative to available PCB space. Evaluate power consumption requirements against other available transceivers if battery life is critical.

Part Context

This part belongs to the ICL32xx series of RS-232 transceivers. It shares functional similarities with other dual driver/receiver models but differs in specific package options and electrical characteristics. The CPZ designation typically indicates a specific packaging variant within the broader product family.

Replacement Considerations

Check for direct pin-compatible alternatives such as the MAX3232 or SP3232. Verify that substitute components support the same voltage range and package dimensions. Ensure signal integrity and timing parameters meet original design requirements.
