ICL3232ECB

Overview

The Intersil ICL3232ECB is a dual driver/receiver RS-232 transceiver integrated circuit designed for serial communication applications. It operates within a power supply voltage range of 3 V to 5.5 V and supports data rates up to 250 kb/s. The device features two drivers and two receivers, enabling full-duplex communication. It includes built-in ESD protection rated at 15 kV. The component draws a typical operating supply current of 1 mA and functions reliably across an ambient temperature range from 0 °C to +70 °C. It is housed in a standard SOIC-16 surface-mount package.

Feature Summary

• Integrated high-voltage charge pump eliminates the need for external positive and negative voltage supplies
• Built-in electrostatic discharge protection rated at 15 kV enhances signal integrity in harsh environments
• Low standby current consumption facilitates battery-powered operation and energy efficiency

Applications

• Industrial control systems requiring robust serial communication links
• Point-of-sale terminals and barcode scanners
• Modems and portable instrumentation equipment

Procurement Notes

Verify the specific suffix against official Renesas or Intersil documentation to confirm pinout compatibility and electrical specifications. Ensure the procurement source provides valid RoHS compliance certificates. Cross-reference the manufacturer part number with authorized distributor databases to validate authenticity before purchase.

Selection Notes

Select this component when a dual-channel RS-232 interface is required for 3 V to 5.5 V logic systems. It is suitable for designs needing moderate data speeds up to 250 kb/s without external charge pump capacitors. Consider the SOIC-16 footprint for PCB layout constraints and verify thermal requirements for the commercial temperature range.

Part Context

The ICL3232ECB belongs to the ICL3232 series of RS-232 transceivers originally developed by Intersil, now managed by Renesas Electronics. This series is widely recognized for its single-supply operation and compact form factor. The EC designation typically indicates the commercial temperature grade and specific packaging variant within the broader product family.

Replacement Considerations

Publicly confirmed substitutes include the MAX3232E and the SP3232EE. Verify that alternative components match the 3 V to 5.5 V supply range and SOIC-16 package dimensions to ensure direct pin-to-pin compatibility.
