MAX3170CAI

Overview

The MAX3170CAI is a multiprotocol transceiver featuring three drivers and three receivers, operating from a single +3.3V supply. It supports V.28 (RS-232), V.11 (RS-449/V.36, EIA530, EIA530-A, X.21), and V.35 protocols. The device operates at data rates up to 10Mbps for V.11/V.35 applications. It utilizes software-selectable DTE/DCE configuration via mode pins. The component includes an internal charge pump and low-dropout transmitter output stages. It is housed in a 28-pin SSOP package.

Feature Summary

• Supports multiple serial communication protocols including RS-232, RS-449, and V.35
• Enables complete DTE or DCE interface ports when paired with companion control and termination devices
• Provides true fail-safe receiver operation to ensure defined logic states during idle conditions
• Integrates fault protection on all transmitter outputs to withstand cable miswiring events

Applications

• CSU/DSU equipment
• Data networking PCI cards
• Data routers

Procurement Notes

Verify the specific suffix 'CAI' against the manufacturer's current part numbering system to confirm package type and temperature range. Confirm RoHS compliance status through official documentation as manufacturing processes may evolve. Check for obsolescence notices or lifecycle changes directly from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component for designs requiring a unified solution for clock, data, and control signals across various serial standards. Ensure compatibility with companion parts like the MAX3171/MAX3173 for control lines and MAX3172/MAX3174 for termination networks. Verify that the +3.3V supply voltage aligns with the system power architecture and that the 28-pin SSOP footprint fits the PCB layout constraints.

Part Context

The MAX3170 forms part of a comprehensive chipset family designed for software-selectable interface ports. It works in conjunction with the MAX3171/MAX3173 for control signal transmission and the MAX3172/MAX3174 for resistor termination networks. This combination allows for flexible configuration of data terminal equipment or data communications equipment interfaces without hardware changes.

Replacement Considerations

The MAX3171CAI+ is listed as a direct substitute in some distributor databases, while the MAX3170CAI+ serves as a parameter-equivalent alternative within the same product line.
