ICL3232EIV-20

Overview

The ICL3232EIV-20 is a dual RS-232 transceiver manufactured by Renesas Electronics under the Intersil brand. It operates on a single power supply ranging from 3 V to 5.5 V and supports full-duplex communication at data rates up to 500 kb/s. The device integrates two drivers and two receivers within a TSSOP-20 surface-mount package. Key electrical specifications include a maximum output current of 35 mA, an operating supply current of 1 mA, and propagation delay of 150 ns. It provides 15 kV electrostatic discharge protection and functions reliably across an industrial temperature range of -40 °C to +85 °C.

Feature Summary

• Integrated high-voltage charge pump circuitry eliminates the need for external positive and negative voltage supplies.
• Enhanced electrostatic discharge protection rated at 15 kV ensures robust performance in electrically noisy environments.
• Low quiescent current consumption facilitates efficient operation in battery-powered applications.

Applications

• Industrial control systems requiring reliable serial communication interfaces.
• Portable instrumentation utilizing low-voltage power sources.
• Data acquisition modules interfacing with PC-based controllers.

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and thermal characteristics. Confirm that the procurement channel provides valid traceability records. Ensure the component meets RoHS directives if required by the target assembly process. Cross-reference the part number with the latest datasheet revision to validate all electrical parameters before integration into production designs.

Selection Notes

Select this component when a dual-channel RS-232 interface is required in a compact TSSOP-20 footprint. It is suitable for designs needing 15 kV ESD immunity without external bias generation. Compare it against standard variants if higher data rates or additional driver channels are necessary. Ensure the system voltage aligns with the 3 V to 5.5 V operational range for optimal signal integrity.

Part Context

This device belongs to the ICL3232 series of RS-232 transceivers, designed for low-power serial communication. The family typically includes variants with different packaging options and temperature ratings. The ICL3232EIV-20 specifically denotes the industrial grade version housed in a TSSOP-20 package, distinguishing it from commercial grade or alternative form factors within the same functional lineage.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with direct replacements such as the ICL3232EIBNZ only through official manufacturer cross-reference lists. Do not assume pin-to-pin compatibility with other RS-232 ICs without consulting the specific datasheets.
