ICL3245IVZ

Overview

The Intersil ICL3245IVZ is an RS-232 transceiver featuring one driver and five receivers. It operates on a single +3V to +5.5V power supply with a typical operating current of 1mA. The device supports data rates up to 1Mbps and includes enhanced automatic powerdown functionality to minimize power consumption during idle periods. It provides ESD protection rated at ±15kV according to the Human Body Model. The component is housed in a 28-pin SSOP package and is designed for industrial temperature ranges, typically spanning from -40°C to +85°C.

Feature Summary

• Enhanced automatic powerdown circuitry reduces quiescent current significantly when the device is not actively transmitting.
• Integrated charge pump generates required internal voltages for RS-232 signaling without external components.
• Robust electrostatic discharge protection ensures reliability in high-interference environments.

Applications

• Industrial control systems requiring serial communication interfaces
• Medical equipment needing reliable low-power data transmission
• Portable instrumentation utilizing battery-powered operation

Procurement Notes

Verify the specific suffix 'IVZ' against official Renesas/Intersil documentation to confirm the exact temperature grade and packaging variant. Ensure compatibility with existing PCB footprints for the 28-pin SSOP configuration. Cross-reference lead times and availability through authorized distributors as stock levels fluctuate. Confirm RoHS compliance status if required by regional regulations.

Selection Notes

Select this component when a single-driver, multi-receiver RS-232 interface is needed within a compact footprint. Compare against similar models like the ICL3245CAZ for pinout and feature parity. Consider the automatic powerdown feature for applications prioritizing energy efficiency. Verify that the 1Mbps data rate meets system requirements before finalizing the design.

Part Context

The ICL3245 belongs to the broader ICL324x family of RS-232 transceivers manufactured by Intersil, now part of Renesas Electronics. This series is known for combining low power consumption with robust performance in harsh environments. The ICL3245 specifically offers a unique 1+5 configuration, distinguishing it from standard 1+1 or 2+2 variants within the same product line.

Replacement Considerations

Direct substitutes include the ICL3245CAZ and ICL3245EIA, which share similar electrical characteristics and pinouts. Verify that any replacement maintains the same 28-pin SSOP package dimensions. Ensure that the alternative part supports the required voltage range and data speed specifications.
