ICL3232ECV-16

Overview

The ICL3232ECV-16 is a dual RS-232 transceiver manufactured by Renesas Electronics Corporation, designed for full-duplex data communication. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 250 kb/s. The device integrates two drivers and two receivers in a TSSOP-16 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 (ESD) protection on all pins and functions reliably across an industrial temperature range from 0°C to +70°C.

Feature Summary

• Integrated ±15 kV ESD protection on all RS-232 signal pins to enhance system robustness against electrostatic discharge events.
• Low power consumption with a typical operating supply current of 1 mA, suitable for battery-powered applications.
• Compliance with EIA/TIA-232 and V.28/V.24 standards ensuring compatibility with standard serial communication interfaces.

Applications

• Industrial control systems requiring reliable serial communication in electrically noisy environments.
• Portable instrumentation and handheld devices utilizing low-voltage microcontrollers.
• Embedded systems interfacing between logic-level processors and RS-232 peripherals.

Procurement Notes

Verify the specific suffix 'CV' indicates the commercial temperature grade (0°C to +70°C) and TSSOP-16 package configuration. Confirm RoHS compliance status through official manufacturer documentation or certified distributor declarations prior to integration. Ensure ordering quantities align with standard tube packaging formats typically associated with this part number variant.

Selection Notes

Select this component when designing circuits that require dual-channel RS-232 connectivity without a shutdown feature. It is appropriate for applications where the 250 kb/s data rate suffices and a 3 V to 5.5 V supply rail is available. Consider alternative variants if extended temperature ranges or lower power modes are required.

Part Context

This part belongs to the ICL3232E family of RS-232 transceivers, which are successors to earlier Intersil designs now produced by Renesas. The family shares core architecture but varies in package types, temperature grades, and pinout configurations. The ICL3232ECV-16 specifically denotes the commercial grade version in a 16-pin thin-shrink small-outline package.

Replacement Considerations

Direct functional substitutes include the ICL3232ECV-16Z and ICL3232ECAZ-T, noting differences in packaging format such as tubes versus tape-and-reel. Verify pin compatibility and thermal ratings before substituting with other RS-232 transceivers like the MAX3232 series, as voltage tolerances and pinouts may differ.
