MAX3160CAP

Overview

The MAX3160CAP+ is a multiprotocol transceiver operating from +3.0V to +5.5V, housed in a 20-pin SSOP package with a commercial temperature range of 0°C to +70°C. It supports RS-232 and RS-485/RS-422 protocols via pin-programmable configuration. The device features two drivers and two receivers, achieving data rates up to 250kbps with slew-rate limiting or up to 1Mbps (RS-232) and 10Mbps (RS-485) without it. Standby current is typically 2.5mA, reducing to 1µA in shutdown mode.

Feature Summary

• Pin-programmable architecture allows dynamic switching between dual-channel RS-232 and single-channel RS-485/RS-422 configurations.
• Integrated dual charge pump generates required voltage levels for RS-232 compliance using a single positive supply.
• Slew-rate limiting minimizes electromagnetic interference and cable reflections during high-speed data transmission.
• True fail-safe receiver design prevents false logic transitions when inputs are open-circuited or shorted.

Applications

• Industrial control systems requiring flexible interface options
• Point-of-sale equipment needing protocol adaptability
• RS-232 to RS-485 interface converters
• Networking peripherals and embedded controllers

Procurement Notes

Verify the specific suffix 'CAP+' indicates the lead-free, RoHS-compliant variant within the commercial temperature range. Confirm the 20-pin SSOP package matches the target board footprint. Ensure the ordering code aligns with the intended operational temperature limits for the deployment environment.

Selection Notes

Select this component when a single physical interface must support multiple communication standards. The MAX3160 is optimized for multiprotocol operation on a single bus by multiplexing I/O pins. Consider the MAX3161 if separate transmitter outputs are required, or the MAX3162 for simultaneous independent operation of both protocols.

Part Context

This part belongs to the MAX3160/MAX3161/MAX3162 family of programmable multiprotocol transceivers manufactured by Analog Devices/Maxim Integrated. The MAX3160 specifically utilizes a flow-through pinout in a compact 20-pin SSOP package to facilitate board layout while supporting both RS-232 and RS-485/422 standards.

Replacement Considerations

MAX3160EAP+ serves as the extended temperature (-40°C to +85°C) equivalent. For applications requiring simultaneous independent RS-232 and RS-485 channels, consider the MAX3162 series.
