ICL3245CA-T

Overview

The ICL3245CA-T is a single-driver, five-receiver RS-232 transceiver manufactured by Renesas Electronics. It operates on a single +3V to +5.5V power supply and supports data rates up to 1Mbps. The device features enhanced automatic powerdown functionality, reducing operating current to 1mA. It provides ESD protection rated at 15kV and functions within an industrial temperature range of -40°C to +85°C. Packaged in a 28-pin SSOP, it is designed for surface-mount applications requiring reliable serial communication interfaces.

Feature Summary

• Enhanced automatic powerdown circuitry reduces active current consumption significantly during idle periods.
• Integrated charge pump generates required RS-232 voltage levels from a single low-voltage supply.
• High electrostatic discharge protection ensures robustness against static events on interface lines.

Applications

• Industrial control systems requiring reliable serial communication
• Portable battery-powered equipment needing low standby current
• Embedded systems with limited power supply rails

Procurement Notes

Verify the specific suffix 'CA' indicates the commercial temperature grade (0°C to +70°C) if sourced from distributors listing that variant, as datasheets often group 'E' (industrial) and 'C' (commercial) grades. Confirm moisture sensitivity level and reflow soldering profiles match assembly requirements. Ensure the reel or cut tape packaging aligns with pick-and-place capabilities.

Selection Notes

Select this component when a single driver and multiple receivers are needed for RS-232 links. Compare against the ICL3245EIAZ-T if an extended industrial temperature range (-40°C to +85°C) is mandatory, as the 'CA' suffix typically denotes commercial range (0°C to +70°C). Verify pin compatibility with existing PCB layouts designed for the SSOP-28 package.

Part Context

This part belongs to the Intersil/Renesas ICL3245 family of low-power RS-232 transceivers. It shares architectural similarities with the ICL3243 and ICL3248 but differs in driver/receiver counts. The 'T' suffix denotes tape-and-reel packaging, distinguishing it from tube-packaged variants like ICL3245CAZ.

Replacement Considerations

ICL3245EIAZ-T: Identical electrical function but guaranteed for extended industrial temperature range (-40°C to +85°C). ICL3245CAZ: Same commercial temperature grade but packaged in tubes instead of tape-and-reel. MAX3245: Pin-compatible alternative from Maxim Integrated with similar specifications.
