MAX3160EEAP+T

Overview

The MAX3160EEAP+T is a multiprotocol transceiver from Analog Devices/Maxim Integrated, housed in a 20-pin SSOP package. It supports RS-232 and RS-485/RS-422 interfaces with ±15kV ESD protection per the Human Body Model. The device operates on a single +3.0V to +5.5V supply using an internal dual charge pump, eliminating the need for bipolar voltages. It features pin-selectable transmitter slew rates, allowing data rates up to 1Mbps for RS-232 and 10Mbps for RS-485/RS-422. In shutdown mode, the supply current drops to 1µA (10nA typical).

Feature Summary

• Pin-programmable architecture allows flexible configuration between RS-232 and RS-485/RS-422 modes.
• Integrated dual charge pump enables single-supply operation without external bipolar voltage rails.
• High robustness provided by ±15kV ESD protection and comprehensive fault protection on all I/O lines.

Applications

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

Procurement Notes

Verify the component against official manufacturer datasheets to confirm authenticity. Ensure the specific ordering suffix matches the required temperature range and packaging format. Cross-reference the part number with authorized distributors to validate current availability status before finalizing procurement plans.

Selection Notes

Select this component when a single IC must support both RS-232 and RS-485/RS-422 protocols. It is suitable for designs requiring high ESD immunity and low power consumption. Verify that the 20-pin SSOP package dimensions fit the target PCB layout constraints.

Part Context

This device belongs to the MAX3160E/MAX3161E/MAX3162E family of multiprotocol transceivers. While the MAX3161E uses a 24-pin package and the MAX3162E uses a 28-pin package for simultaneous multi-interface operation, the MAX3160E utilizes a 20-pin SSOP package optimized for multiprotocol bus sharing.

FAQ

How does the FAST input affect data transmission?

The FAST input selects the transmitter slew rate. Asserting it disables slew-rate limiting, enabling higher data rates up to 10Mbps for RS-485/RS-422 and 1Mbps for RS-232.

What is the function of the SHDN pin?

Driving the SHDN pin low shuts down the charge pump and transmitters, reducing the supply current to approximately 10nA while keeping RS-232 receivers active.
