MAX3245CWI

Overview

The MAX3245CWI+ is a single-supply RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features three drivers and five receivers, supporting full-duplex communication at data rates up to 1Mbps. The device operates from a +3.0V to +5.5V supply with a typical shutdown current of 1µA enabled by AutoShutdown Plus technology. It utilizes a dual charge pump requiring four small capacitors for voltage conversion. The component is housed in a 28-pin SOIC Wide (SO-Wide) package and is rated for an operating temperature range of 0°C to +70°C.

Feature Summary

AutoShutdown Plus functionality automatically reduces power consumption when the interface is idle or disconnected.
MegaBaud operation guarantees reliable high-speed data transmission up to 1Mbps.
Integrated INVALID output signal detects valid RS-232 receiver input levels independently of shutdown states.
Proprietary low-dropout transmitter stage ensures true RS-232 performance across the specified voltage range.

Applications

Notebook, subnotebook, and palmtop computers
Cellular phones and handheld equipment
Battery-powered peripherals and printers

Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C), distinct from the industrial 'E' variant (-40°C to +85°C). Confirm RoHS compliance status via the manufacturer's official documentation before finalizing procurement specifications.

Selection Notes

Select this model for applications requiring three transmit and five receive channels on a single chip. Ensure the system design accommodates the required external capacitors for the internal charge pump. Verify that the 1Mbps data rate meets the application requirements, as lower-speed variants exist within the same family.

Part Context

This component belongs to the MAX32xx series of EIA/TIA-232 and V.28/V.24 communications interfaces. It shares core architectural features with the MAX3224–MAX3227 and MAX3244 models, specifically regarding the AutoShutdown Plus mechanism and dual charge pump topology.

Replacement Considerations

Public confirmed substitute part numbers include MAX3245ECWI+T and MAX3245EEAI+T. These variants offer identical functional specifications but differ in their operating temperature ranges and packaging options.
