ICL3245ECV

Overview

The ICL3245ECV is a low-power RS-232 transceiver manufactured by Intersil, designed for operation within a +3V to +5.5V supply range. It supports data rates up to 1Mbps and features enhanced automatic powerdown capabilities that reduce quiescent current to 1µA in standby mode. The device integrates three drivers and five receivers, providing full-duplex communication. On-chip voltage converters require only four external 0.1µF capacitors. It meets EIA/TIA-232 and V.28/V.24 specifications at 3V and includes receiver hysteresis for improved noise immunity.

Feature Summary

• Enhanced automatic powerdown functionality significantly reduces power consumption during idle periods.
• Integrated charge pump eliminates the need for external DC-DC converters, requiring only small capacitors.
• Receiver input hysteresis provides robust noise immunity for reliable signal detection.
• Drop-in replacement compatibility with industry-standard MAX3245 devices.

Applications

• Industrial serial communication systems requiring low power consumption
• Portable battery-operated equipment utilizing RS-232 interfaces
• Embedded systems needing full-duplex data transmission over short distances

Procurement Notes

Verify the specific suffix 'ECV' indicates the TSSOP-28 package variant when sourcing. Confirm RoHS compliance status as it may vary by production batch or region. Ensure the supplier provides valid traceability documentation for the Intersil or Renesas brand origin. Cross-reference the ordering part number against the manufacturer's latest datasheet to confirm pinout and electrical characteristics match the design requirements before finalizing procurement.

Selection Notes

Select this component for applications requiring full-duplex RS-232 communication with minimal power draw. It is suitable for designs operating between 3V and 5.5V where space constraints limit external capacitor size. Choose this part if drop-in replacement for MAX3245 is required without redesigning the PCB layout. Consider the TSSOP-28 package for surface-mount assembly needs.

Part Context

The ICL3245ECV belongs to the ICL3245E family of RS-232 transceivers from Intersil, now part of Renesas Electronics. This series is characterized by its ability to operate at lower voltages while maintaining standard RS-232 signal levels. The EC suffix typically denotes the specific package type and temperature range variations within the broader product line.

Replacement Considerations

Publicly confirmed direct substitutes include the MAX3245. Verify pin-to-pin compatibility and electrical parameter equivalence before swapping components in existing designs.
