ICL3238EIV

Overview

The ICL3238EIV is a low-power RS-232 transceiver manufactured by Intersil, now part of Renesas Electronics. It integrates five drivers and three receivers in a single package, supporting full-duplex communication at data rates up to 250 kb/s. The device operates from a single power supply ranging from 3 V to 5.5 V, with a typical operating current of 1 mA. It features 15 kV electrostatic discharge (ESD) protection on all pins and is housed in a 28-pin TSSOP package suitable for surface-mount installation.

Feature Summary

• Integrates five independent drivers and three receivers for comprehensive RS-232 connectivity within a compact form factor.
• Provides robust 15 kV ESD protection across all signal pins to enhance reliability in harsh environments.
• Operates efficiently on a single 3 V to 5.5 V supply with ultra-low standby current consumption.

Applications

• Industrial control systems requiring reliable serial communication interfaces.
• Portable battery-powered devices utilizing RS-232 protocols.
• Embedded systems needing multiple transmit and receive channels.

Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range operation (-40°C to +85°C). Confirm the 'V' suffix corresponds to the TSSOP-28 package type. Check current availability status as this component may be subject to end-of-life notices or discontinuation by the manufacturer. Ensure compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component when five driver outputs and three receiver inputs are required simultaneously. It is suitable for applications demanding high ESD immunity without external protection components. Consider the 250 kb/s speed limit when designing for higher baud rate requirements. Verify that the 3 V to 5.5 V supply voltage aligns with the system's power architecture.

Part Context

This part belongs to the ICL3238 series of RS-232 transceivers. It shares functional similarities with other multi-driver RS-232 ICs but is distinguished by its specific count of five drivers and three receivers. The device represents Intersil's contribution to low-power serial interface solutions, later integrated into Renesas Electronics' portfolio following corporate acquisitions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult official manufacturer cross-reference guides for compatible alternatives. Ensure any replacement maintains the same pinout configuration and electrical specifications to avoid redesign efforts.
