ICL3245EIV

Overview

The ICL3245EIV is a full-duplex RS-232 transceiver operating from a single +3V to +5.5V supply. It integrates three drivers and five receivers, supporting data rates up to 1Mbps. The device features enhanced automatic powerdown, reducing quiescent current to 1µA in standby mode. Internal charge pumps require only four external 0.1µF capacitors. It meets EIA/TIA-232 and V.28/V.24 specifications with receiver hysteresis for noise immunity. The component operates within a -40°C to +85°C temperature range and is housed in a 28-pin TSSOP package.

Feature Summary

• Integrated charge pump requiring minimal external capacitance
• Enhanced automatic powerdown functionality for low standby current
• Receiver hysteresis designed to improve noise immunity
• Drop-in replacement compatibility with legacy MAX3245 devices

Applications

• Industrial serial communication interfaces
• Portable battery-powered instrumentation
• Modem and communications equipment
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'EIV' corresponds to the 28-TSSOP package and industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status through official Renesas documentation. Ensure ordering quantities match distributor reel or cut-tape specifications. Cross-reference pinouts with target PCB layout to guarantee interface compatibility.

Selection Notes

Select this component when designing 3V to 5.5V RS-232 links requiring multiple receive channels. The integrated power management suits battery-operated applications needing extended standby life. Verify that the 1Mbps speed meets system timing requirements. Consider the TSSOP footprint constraints during mechanical design phase.

Part Context

This part belongs to the Intersil ICL3245E family of RS-232 transceivers. It shares architectural similarities with the ICL3225E and ICL3227E but offers distinct driver/receiver counts. The series emphasizes low-power operation and ease of implementation for standard serial ports.

Replacement Considerations

Officially documented as a drop-in replacement for the Maxim MAX3245. Verify pin-to-pin compatibility before substitution. Check voltage level tolerances and signal integrity requirements against the original design specifications.
