ICL3232EIV-16Z-T

Overview

The ICL3232EIV-16Z-T is a dual RS-232 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 250 kbps. The device features two drivers and two receivers, providing full-duplex communication capabilities. It incorporates ±15 kV ESD protection on all RS-232 lines and meets EIA/TIA-232 and V.28/V.24 specifications. The component is housed in a 16-TSSOP package with a width of 4.40 mm. It functions reliably across an industrial temperature range from -40°C to +85°C and draws approximately 1 µA in shutdown mode.

Feature Summary

• Integrated ±15 kV ESD protection on transmit and receive lines for enhanced robustness
• Compliance with EIA/TIA-232 and V.28/V.24 interface standards
• Low power consumption with microampere-level current draw during shutdown

Applications

• Industrial control systems requiring reliable serial communication
• Portable battery-powered equipment utilizing low-voltage operation
• Data acquisition systems interfacing with RS-232 peripherals

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration distinct from tube variants. Confirm the 'E' designation aligns with the required extended temperature grade and ESD protection levels specified in the official datasheet. Ensure the 16-TSSOP footprint matches the target PCB layout dimensions before finalizing procurement orders.

Selection Notes

Select this component when dual-channel RS-232 connectivity is required within a 3 V to 5.5 V power domain. It is suitable for designs prioritizing high ESD immunity without external protection components. Consider alternative pin counts if more than two channels are needed or if space constraints require a smaller package type than the 16-TSSOP form factor.

Part Context

This part belongs to the ICL3232 series of RS-232 transceivers, which are designed for low-power applications. The series includes variations such as the ICL3232EIV-16Z and ICL3232IVZ-T7A, differing primarily in packaging format and specific manufacturing lot characteristics while maintaining core electrical performance parameters defined by the manufacturer.

Replacement Considerations

The ICL3232EIV-16Z is a compatible tube-packaged variant from the same manufacturer. Cross-referencing with other manufacturers requires verifying pin compatibility and ensuring equivalent ESD protection ratings and operating voltage ranges are maintained.
