MAX3170CAI+T

Overview

The MAX3170CAI+T is a three-driver/three-receiver multiprotocol transceiver operating from a +3.3V single supply. It supports V.28 (RS-232), V.11, and V.35 protocols with software-selectable DTE/DCE configuration. The device operates at data rates up to 10Mbps for V.11/V.35 applications. It features 3V/5V logic-compatible I/O and true fail-safe receiver operation. Transmitter outputs are fault protected to ±15V. The component is housed in a small 28-pin SSOP package and requires only four surface-mount capacitors for implementation.

Feature Summary

• Software-selectable interface protocol support for RS-232, V.11, and V.35 standards
• Integrated fault protection on transmitter outputs to withstand cable miswiring
• True fail-safe receiver operation ensures defined output states during idle conditions

Applications

• Data networking equipment interfaces
• PCI card serial communication ports
• Channel Service Unit/Data Service Unit (CSU/DSU) implementations
• Telecommunications data routers

Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as indicated by the '+' designation. Check manufacturer documentation for current production lifecycle status, as older Maxim Integrated components may have limited availability or obsolescence notices. Ensure the specific voltage range matches system requirements.

Selection Notes

Select this component when a complete DTE/DCE port solution is required using a single transceiver for clock and data signals. Pair with MAX3171/MAX3173 for control signals and MAX3172/MAX3174 for termination networks if discrete solutions are not preferred. Verify that the 3.3V supply voltage aligns with the target system architecture before finalizing the design.

Part Context

The MAX3170 forms part of the MAX317x family alongside the MAX3171, MAX3172, MAX3173, and MAX3174. This chipset provides a comprehensive software-selectable interface solution. While the MAX3170 handles high-speed clock and data lines, companion devices manage control signals and termination resistors, allowing flexible configuration for various industrial and telecommunications standards.

Replacement Considerations

Direct substitutes within the same family include the MAX3170CAI without the reel suffix. For pin-compatible alternatives supporting similar protocols, evaluate the MAX3171 series for control signal handling. Verify electrical compatibility with existing termination networks designed for the MAX3172/MAX3174 series.
