MAX3160EAP+

Overview

The MAX3160EAP+ is a multiprotocol transceiver from Analog Devices/Maxim Integrated, housed in a 20-pin SSOP package. It operates on a single +3V to +5.5V supply and features an internal dual charge pump for RS-232 compliance. The device supports pin-selectable operation as either a 2TX/2RX RS-232 interface or a single RS-485/RS-422 transceiver. It achieves data rates up to 10Mbps in RS-485/RS-422 mode and 1Mbps in RS-232 mode. The shutdown current is 1µA, and the operating temperature range is -40°C to +85°C.

Feature Summary

• Pin-programmable configuration allows flexible selection between RS-232 and RS-485/RS-422 protocols within a single package.
• Integrated dual charge pump eliminates the need for external bipolar power supplies, enabling single-supply operation.
• Pin-selectable transmitter slew rates minimize electromagnetic interference and reduce cable reflections.
• True fail-safe receiver design prevents false transitions during input short circuits or open conditions.

Applications

• Point-of-Sales Equipment
• Industrial Controls
• Networking Interface Converters

Procurement Notes

Verify the component against official manufacturer documentation to confirm authenticity and specifications. Ensure the ordering suffix matches the required temperature range and package type. Cross-reference with authorized distributors to validate part availability and sourcing channels.

Selection Notes

Select this component when a single IC must support both RS-232 and RS-485/RS-422 interfaces via pin programming. It is suitable for designs requiring low standby power and high-speed data transmission up to 10Mbps. Verify that the 20-pin SSOP package fits the board layout constraints.

Part Context

This part belongs to the MAX3160/MAX3161/MAX3162 family of multiprotocol transceivers. The 'E' suffix indicates an extended temperature range of -40°C to +85°C, while the 'P+' suffix denotes a lead-free, RoHS-compliant SSOP-20 package.

FAQ

How does the MAX3160EAP+ handle protocol switching?

The device is pin-programmable. Asserting the RS485/RS232 pin configures it as a single RS-485 transceiver, while de-asserting it configures it as a 2TX/2RX RS-232 interface.

What is the purpose of the FAST pin?

The FAST pin selects the slew rate limiting. Driving it low limits the slew rate to reduce EMI, while driving it high enables full-speed operation up to 10Mbps for RS-485/RS-422 and 1Mbps for RS-232.
