ICL3207ECA

Overview

The ICL3207ECA is a low-power RS-232 transceiver manufactured by Intersil, now part of Renesas Electronics. It integrates five drivers and three receivers within a single package, supporting full-duplex communication at data rates up to 500 kb/s. The device operates on a single power supply ranging from 3 V to 5.5 V, with a typical operating current of 1 mA. It features robust electrostatic discharge (ESD) protection rated at 15 kV for both air gap and human body models. The component is housed in a 24-pin SSOP package and is designed for commercial temperature ranges spanning 0°C to +70°C.

Feature Summary

• Integrates five independent drivers and three receivers for comprehensive serial communication interfaces.
• Provides enhanced 15 kV ESD protection on all RS-232 pins to safeguard connected equipment.
• Operates efficiently on a single 3 V to 5.5 V power supply with minimal quiescent current consumption.

Applications

• ISDN Terminal Adaptors requiring reliable serial connectivity.
• Portable computing devices such as PDAs and Palmtops where space and power are constrained.
• Peripheral interface circuits in notebook and laptop computer systems.

Procurement Notes

Verify the specific suffix and manufacturer source carefully, as Intersil operations have transitioned to Renesas Electronics. Confirm that the 15 kV ESD protection rating aligns with your system's environmental requirements. Ensure the commercial temperature range meets your operational needs. Check for RoHS compliance status depending on the production batch. Validate the SSOP-24 footprint compatibility during the PCB layout phase.

Selection Notes

Select this component when a high driver count is necessary alongside low power consumption. It serves as a direct replacement for legacy parts like the MAX207E or HIN207E in 3V systems. Consider the 15 kV ESD rating if the application involves frequent human contact. Verify that the 500 kb/s speed suffices for the target protocol. Ensure the 24-pin SSOP package fits the available board real estate constraints.

Part Context

This device belongs to the ICL32X7E family of low-power RS-232 transceivers. The 'E' suffix typically denotes enhanced ESD protection capabilities compared to standard variants. The ICL3207 variant specifically provides a 5-driver and 3-receiver configuration, distinguishing it from lower-channel counterparts in the same series.

Replacement Considerations

Publicly confirmed substitutes include the MAX207E and HIN207E. These components offer similar functionality but may require verification of pinout compatibility and exact ESD ratings before implementation.
