MAX3160EAP/GG8

Overview

The MAX3160EAP+ is a multiprotocol transceiver supporting RS-232, RS-485, and RS-422 standards. It operates on a single +3.0V to +5.5V supply using an internal dual charge pump. The device features pin-programmable configurations for two TX/RX RS-232 channels or a single RS-485/422 transceiver. Electrical parameters include a maximum data rate of 10Mbps in RS-485 mode and 1Mbps in RS-232 mode. Standby current is typically 2.5mA, reducing to 1µA in shutdown. Operating temperature ranges from -40°C to +85°C.

Feature Summary

• Pin-programmable architecture allows dynamic switching between RS-232 and RS-485/422 protocols without hardware changes.
• Integrated dual charge pump eliminates the need for external bipolar power supplies.
• Fail-safe receiver design prevents false transitions during input shorting or open-circuit conditions.
• Slew-rate limiting minimizes electromagnetic interference and cable reflections.

Applications

• Industrial controls
• Point-of-Sales equipment
• RS-232 to RS-485 interface converters

Procurement Notes

Verify the specific suffix 'EAP+' confirms the extended temperature range (-40°C to +85°C) and SSOP-20 package. Confirm RoHS compliance status with the supplier. Ensure the ordering quantity matches the tube packaging format specified by Analog Devices.

Selection Notes

Select this component when a single interface port requires protocol flexibility. The MAX3160 shares I/O pins between protocols, making it suitable for space-constrained designs. Compare against MAX3161 if separate physical ports are required for simultaneous operation.

Part Context

This part belongs to the MAX3160/MAX3161/MAX3162 family of multiprotocol transceivers. The MAX3160 specifically offers a flow-through pinout optimized for multiprotocol operation on a single bus within a compact 20-pin SSOP package.

Replacement Considerations

MAX3160CAP+ (Commercial Temperature Range). Verify pin compatibility and thermal specifications before substitution.

FAQ

How is the communication protocol selected?

Protocol selection is controlled via the RS485/RS232 and HDPLX logic pins. Asserting these pins configures the device as either an RS-232 interface or an RS-485/422 transceiver.

What is the purpose of the FAST pin?

The FAST pin selects the slew rate. Driving it high disables slew-rate limiting, enabling higher data rates up to 10Mbps for RS-485 and 1Mbps for RS-232.
