ICL3217ECAZ-T

Overview

The ICL3217ECAZ-T is a low-power RS-232 transceiver manufactured by Renesas Electronics Corporation, operating on a single +3V to +5.5V supply. It integrates five transmitters and three receivers, supporting data rates up to 250kbps while meeting EIA/TIA-232 and V.28/V.24 specifications at 3.0V. The device features ±15kV ESD protection on RS-232 I/O pins (IEC61000-4-2 Air Gap) and Human Body Model standards. It utilizes efficient on-chip charge pumps and an automatic powerdown function that reduces standby supply current to 1µA when peripheral devices are powered off or cables are removed.

Feature Summary

• Automatic powerdown circuitry conserves system power by reducing standby current to 1µA when idle.
• Robust ±15kV ESD protection on RS-232 input/output pins ensures reliability in harsh environments.
• Efficient on-chip charge pumps enable operation with small external capacitors, minimizing board space requirements.

Applications

• ISDN Terminal Adaptors
• Personal Digital Assistants (PDAs)
• Palmtops and portable peripherals
• Notebook and laptop computers

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation. Ensure compatibility with existing 3.3V and 5V mixed voltage systems during integration planning.

Selection Notes

Select this component for applications requiring low operational and standby power consumption. It serves as a lower power replacement for legacy MAX207E, HIN207E, and HIN237E devices. Suitable for systems where automatic power management and compact footprint are critical design constraints.

Part Context

This part belongs to the Intersil ICL32X7E family of RS-232 transmitters and receivers. The family is designed for 3V to 5.5V powered systems, providing full duplex communication capabilities with latch-up free performance across the commercial temperature range.

Replacement Considerations

Officially documented as a lower power replacement for MAX207E, HIN207E, and HIN237E. Verify pinout and capacitor requirements against these legacy equivalents before substitution.
