MAX3160ECAP+

Overview

The MAX3160ECAP+T is a multiprotocol transceiver from Analog Devices/Maxim Integrated, housed in a 20-pin SSOP package. 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 (up to 1Mbps) and RS-485/RS-422 (up to 10Mbps) data rates with pin-selectable slew-rate limiting for reduced EMI. It includes an integrated dual charge pump, true fail-safe receivers, and a shutdown mode drawing 1µA. Operating temperatures range from -40°C to +85°C.

Feature Summary

• Pin-programmable configuration allows operation as either a 2Tx/2Rx RS-232 interface or a single RS-485/RS-422 transceiver.
• Integrated dual charge pump enables compliant RS-232 and RS-485/RS-422 performance using only a single positive voltage supply.
• Enhanced robustness provided by ±15kV ESD protection on all transmitter outputs and receiver inputs.

Applications

• Point-of-Sales Equipment
• Industrial Controls
• Networking
• RS-232 to RS-485 Interface Converters

Procurement Notes

Verify the specific suffix 'CAP+' against official documentation to confirm lead-free status and RoHS compliance. Confirm that the 'E' designation matches the required extended temperature range of -40°C to +85°C for your application environment. Ensure the 20-pin SSOP footprint aligns with your PCB layout constraints before finalizing procurement.

Selection Notes

Select the MAX3160E when multiplexing a single UART across two different interface buses is required. This model shares logic lines between protocols, making it distinct from the MAX3161E which offers separate I/O ports. Verify that the flow-through pinout meets your board routing requirements compared to other variants in the family.

Part Context

This component belongs to the MAX3160E/MAX3161E/MAX3162E series of programmable multiprotocol transceivers. These devices are designed to provide flexible interface options within a single package, eliminating the need for multiple discrete components. The series utilizes proprietary low-dropout transmitter stages and internal charge pumps to support various communication standards efficiently.
