MAX3160CAP+

Overview

The MAX3160CAP+ is a multiprotocol transceiver from Analog Devices/Maxim Integrated, housed in a 20-pin SSOP package. It supports +3V to +5.5V single-supply operation with an on-board dual charge pump eliminating the need for bipolar supplies. The device operates within a commercial temperature range of 0°C to +70°C and features a shutdown supply current of 1µA. In RS-485/422 mode, it achieves data rates up to 10Mbps without slew-rate limiting or 250kbps with limiting enabled. RS-232 mode supports up to 1Mbps (FAST) or 250kbps (slew-limited). It includes integrated protection against wiring faults, short circuits, and thermal overload.

Feature Summary

• Pin-programmable configuration allows selection between a 2TX/2RX RS-232 interface or a single RS-485/422 transceiver.
• Integrated dual charge pump circuitry enables compliant RS-232 and RS-485/422 performance using only a single positive voltage supply.
• Pin-selectable transmitter slew rates minimize electromagnetic interference and reduce cable reflections during data transmission.
• True fail-safe receiver design prevents false logic transitions when inputs are open, shorted, or disconnected.

Applications

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

Procurement Notes

Verify the ordering suffix 'CAP+' indicates a lead-free and RoHS-compliant package variant. Confirm the specific temperature grade corresponds to the commercial range (0°C to +70°C) required for the target application environment. Ensure the 20-pin SSOP footprint matches the printed circuit board layout constraints.

Selection Notes

Select this component when a single-chip solution is needed to support both RS-232 and RS-485 protocols via pin programming. It is suitable for designs requiring low power consumption with a 1µA shutdown state. Verify that the 20-pin SSOP package size fits the available board space compared to larger packages like the 24-pin or 28-pin variants found in the same family.

Part Context

This part belongs to the MAX3160/MAX3161/MAX3162 family of multiprotocol transceivers. While the MAX3161 uses a 24-pin SSOP and the MAX3162 utilizes a 28-pin SSOP for simultaneous protocol operation, the MAX3160 specifically offers a 20-pin SSOP form factor optimized for multiprotocol operation on a single interface bus through pin multiplexing.
