ICL3207CA-T

Overview

The ICL3207CA-T is a low-power RS-232 transceiver manufactured by Intersil, now part of Renesas Electronics. It operates on a single power supply ranging from +3V to +5.5V and supports data rates up to 250 kbps. The device integrates five drivers and three receivers, providing full-duplex communication compliant with EIA/TIA-232 and V.28/V.24 standards. It features an automatic powerdown function that reduces standby current to approximately 1 µA when no valid signal is detected. The component is housed in a 24-pin SSOP package and is rated for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates five drivers and three receivers for comprehensive RS-232 connectivity
• Features automatic powerdown circuitry to minimize standby power consumption
• Operates reliably with single +3V to +5.5V power supplies
• Includes on-chip charge pumps requiring only small external capacitors

Applications

• ISDN Terminal Adaptors
• Portable computers such as PDAs and Palmtops
• Notebook and laptop computer peripherals
• Battery-powered systems requiring low standby current

Procurement Notes

Verify the specific suffix CA-T against official Renesas or Intersil documentation to confirm package type and temperature grade. Confirm end-of-life status and availability through authorized distributors, as this component may be discontinued. Ensure moisture sensitivity levels are addressed during storage and handling procedures.

Selection Notes

Select this component when designing systems requiring multiple transmit lines and fewer receive lines within a compact footprint. It is suitable for applications needing low power consumption in both active and standby modes. Verify that the 250 kbps speed meets system requirements and that the SSOP-24 package fits the PCB layout constraints.

Part Context

The ICL3207 belongs to the ICL32X7E family of low-power RS-232 transceivers designed for 3V to 5.5V operation. This series targets portable electronics where board space and battery life are critical. The ICL3207 variant specifically provides a 5-driver/3-receiver configuration, distinguishing it from other members of the family with different driver/receiver counts.

Replacement Considerations

The MAX207E and HIN207E are cited as higher-power predecessors that this device replaces. Check datasheets for pin compatibility and capacitor requirements when substituting these older components.
