MAX13173EETU+

Specialized Overview

The MAX13173EETU+ is a multiprotocol, pin-selectable data interface transceiver designed for control signal transmission in DTE/DCE environments. It supports V.28 (RS-232), V.10/V.11 (RS-449/V.36, RS-530, RS-530A, X.21), and V.35 protocols. Operating from a single +3.135V to +5.5V supply, it features an internal charge pump generating VDD (+4.16V to +5.7V) and VEE (-4.16V to -5.89V). The device includes short-circuit current limiting, thermal shutdown at +145°C, and extended ESD protection up to ±15kV HBM. It operates over the -40°C to +85°C temperature range in a 38-pin TQFN package.

Specialized Feature Summary

• Pin-selectable configuration for DTE or DCE modes across multiple serial protocols
• Integrated charge pump eliminates external negative voltage generation requirements
• Flexible logic reference input allows interfacing with systems down to 1.62V
• True fail-safe receivers maintain compatibility while ensuring defined states

Specialized Applications

• Data networking equipment including routers and switches
• PCI cards requiring high-speed serial interfaces
• Channel Service Unit/Data Service Unit (CSU/DSU) implementations
• Telecommunication terminal equipment

Specialized Procurement Notes

Verify the component matches the specific MAX13173EETU+ designation, which indicates the -40°C to +85°C temperature range and 38-pin TQFN-EP package. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ordering suffixes align with exact thermal and packaging specifications required by the design.

Specialized Selection Notes

Select this component when designing interfaces that require support for V.10, V.11, V.28, and V.35 protocols within a single port architecture. It is suitable for applications needing pin-selectable termination via the companion MAX13175E. Consider the 38-pin TQFN footprint and exposed pad thermal requirements during PCB layout planning.

Specialized Part Context

This part belongs to the MAX1317x series chipset, functioning alongside the MAX13171E for data signals and the MAX13175E for termination networks. While the MAX13171E handles clock and data lines, the MAX13173E specifically manages control signals such as CTS, RTS, DCD, and DSR. This division of labor optimizes signal integrity for complex multiprotocol terminals.
