ICL3238EIVZ-T

Overview

The ICL3238EIVZ-T is a multichannel RS-232 line driver and receiver manufactured by Renesas Electronics. It operates on a single power supply ranging from 3 V to 5.5 V, supporting both 3.3 V and 5 V logic systems. The device integrates five drivers and three receivers, providing full-duplex communication capabilities with a data rate of up to 250 kb/s. It features low operating supply current of 1 mA and includes 15 kV electrostatic discharge (ESD) protection on all lines. The component is housed in a 28-pin TSSOP package and is rated for an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates five independent drivers and three receivers for comprehensive multichannel serial communication.
• Provides robust 15 kV ESD protection across all signal lines to enhance system reliability.
• Operates efficiently with low supply current consumption suitable for battery-powered applications.

Applications

• Industrial control systems requiring reliable serial communication interfaces.
• Portable equipment utilizing 3 V or 5 V power supplies.
• Data acquisition systems needing multiple RS-232 channels.

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this variant. Confirm the manufacturer status as Renesas Electronics Corporation, noting that Intersil branding may appear on legacy documentation. Ensure the part number matches the exact pinout and electrical specifications required for the design.

Selection Notes

Select this component when five transmit and three receive channels are necessary within a single IC footprint. It is appropriate for designs requiring operation between 3 V and 5.5 V without external charge pumps. Consider the TSSOP-28 package constraints and the 250 kb/s speed limit relative to higher-speed alternatives.

Part Context

This part belongs to the ICL3238 series of RS-232 transceivers. It shares functional similarities with other multichannel devices but is distinguished by its specific configuration of five drivers and three receivers. The 'E' designation typically denotes the extended industrial temperature range, while 'IVZ' specifies the TSSOP-28 package type.

Replacement Considerations

The MAX3238EIPWR from Texas Instruments offers comparable functionality with five drivers and three receivers in a similar voltage range. Verify pin-to-pin compatibility and ensure the replacement supports the required 250 kb/s data rate and ESD protection levels before substitution.
