MAX3160ECAP+T

Overview

The MAX3160ECAP+T is a multiprotocol transceiver from the MAX3160E series, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +3.0V to +5.5V supply and features ±15kV ESD protection per the Human Body Model. The device supports RS-232, RS-485, and RS-422 protocols with pin-selectable configurations. It includes an internal dual charge pump for RS-232 voltage generation without external bipolar supplies. Key electrical parameters include a maximum data rate of 250kbps in slew-rate limited mode and up to 10Mbps in fast mode for RS-485/RS-422. The shutdown current is 1µA (typical), and it operates within a temperature range of -40°C to +85°C.

Feature Summary

• Pin-programmable architecture allows flexible configuration between RS-232 and RS-485/RS-422 modes.
• Integrated dual charge pump eliminates the need for external bipolar power supplies.
• High robustness with ±15kV ESD protection and true fail-safe receiver inputs.
• Slew-rate limiting minimizes electromagnetic interference and cable reflections.

Applications

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

Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm that the ordering suffix matches the specific package type and temperature grade required for the design. Ensure compliance with RoHS directives as indicated in the product specifications before finalizing procurement orders.

Selection Notes

Select this component when a single IC must support multiple serial communication standards. The flow-through pinout facilitates board layout compared to other variants in the family. Consider the SSOP-20 package constraints and verify that the application requires the specific I/O multiplexing capabilities defined for the MAX3160E variant.

Part Context

This part belongs to the MAX3160E/MAX3161E/MAX3162E family of multiprotocol transceivers. The 'E' suffix denotes the extended industrial temperature range (-40°C to +85°C). The 'CAP' suffix indicates the SSOP-20 package and tape-and-reel shipping method. It shares core functionality with the MAX3161E and MAX3162E but differs in pin multiplexing and package count.

FAQ

How does the FAST pin affect data transmission?

Asserting the FAST pin disables slew-rate limiting, allowing data rates up to 10Mbps for RS-485/RS-422 and 1Mbps for RS-232. Deasserting it limits the slew rate to reduce EMI at lower speeds like 250kbps.

What is the function of the SHDN pin?

Driving the SHDN pin low shuts down the charge pump and transmitters, reducing supply current to approximately 1µA. The RS-232 receivers remain active if configured in RS-232 mode.

Does the device require external capacitors for operation?

Yes, the internal dual charge pump requires external flying capacitors (C1, C2) and bypass capacitors (C3, C4) to generate the necessary voltages for RS-232 and RS-485/RS-422 operation.
