MAX3160CAP+T

Overview

The MAX3160CAP+T is a multiprotocol transceiver supporting RS-232 and RS-485/RS-422 interfaces. It operates on a single +3V to +5.5V supply using an internal dual charge pump, eliminating the need for external bipolar voltages. The device features pin-selectable slew rates, enabling data transmission up to 250kbps with limiting or up to 1Mbps in RS-232 mode without limiting. It includes integrated protection against wiring faults, short circuits, and thermal overload. The component is housed in a 20-pin SSOP package and supports a commercial operating temperature range of 0°C to +70°C.

Feature Summary

• Pin-programmable configuration allows flexible selection between RS-232 and RS-485/RS-422 modes within a single package.
• Integrated dual charge pump circuitry enables compliant performance from a single low-voltage power supply.
• Built-in fail-safe receiver logic prevents false transitions during input shorts or open-circuit conditions.
• Slew-rate limiting functionality minimizes electromagnetic interference and reduces signal reflections.

Applications

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

Procurement Notes

Verify that the ordering suffix CAP indicates the commercial temperature range (0°C to +70°C) and the 20-pin SSOP package format. Confirm RoHS compliance and lead-free status as specified by the '+' designation. Ensure the specific revision level matches the design requirements before finalizing procurement orders.

Selection Notes

Select this model when a single interface must support both RS-232 and RS-485 protocols via pin programming. It is suitable for designs requiring low standby current and simplified board layouts due to the flow-through pinout. Consider alternative models if simultaneous independent operation of both protocols is required rather than selectable modes.

Part Context

This component belongs to the MAX3160/MAX3161/MAX3162 family of multiprotocol transceivers manufactured by Analog Devices Inc./Maxim Integrated. The MAX3160 variant specifically provides a 20-pin SSOP footprint optimized for multiprotocol operation on a single interface bus through shared I/O pin multiplexing.
