ICL3232ECV-20T

Overview

The ICL3232ECV-20T is an RS-232 transceiver manufactured by Renesas Electronics under the Intersil brand. It operates within a supply voltage range of 3 V to 5.5 V, supporting both 3.3 V and 5 V logic systems. The device features one driver and two receivers with a data rate capability of 500 kb/s. It utilizes a TSSOP-20 surface-mount package and includes 15 kV ESD protection on all pins. The component functions without a shutdown mode and draws a typical operating supply current of 1 mA.

Feature Summary

• Provides full-duplex communication via integrated drivers and receivers for RS-232 signaling.
• Incorporates robust electrostatic discharge protection rated at 15 kV across input and output pins.
• Designed for low power consumption with a minimal operating supply current specification.

Applications

• Serial communication interfaces in portable battery-operated devices
• Industrial control systems requiring reliable RS-232 connectivity
• Embedded systems utilizing 3.3 V or 5 V logic levels

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this part number. Confirm the manufacturer designation as Renesas Electronics, which acquired Intersil, to ensure authenticity. Check for RoHS compliance documentation and moisture sensitivity level ratings prior to procurement. Ensure the supplier provides valid traceability records for the component batch.

Selection Notes

Select this component when a single driver and dual receiver configuration is required for RS-232 applications. It is suitable for designs needing 500 kb/s data rates within a 3 V to 5.5 V supply range. The TSSOP-20 package is appropriate for space-constrained printed circuit board layouts. Consider the 15 kV ESD protection if the interface is exposed to high-static environments.

Part Context

This component belongs to the ICL3232 series of RS-232 transceivers. The family typically offers variations in pin counts and driver/receiver configurations. The ICL3232ECV-20T specifically denotes the 20-pin TSSOP variant with one driver and two receivers. It represents a standard solution for legacy serial port implementations in modern low-voltage digital systems.

Replacement Considerations

Compatible substitutes include the ICL3232ECV-20Z for tube packaging variants. Other members of the ICL3232 family may serve as alternatives if pin compatibility and electrical specifications align with the design requirements.
