What are the key features of MAX211CDBG4?

4 transmitters and 5 receivers in a single device eliminate external level-shifter components for complete RS-232 port implementation
On-chip charge pump generates ±10V RS-232 voltage levels from a single 5V supply without external DC-DC converter
Schmitt trigger receiver inputs provide hysteresis for noise immunity and clean signal transitions in electrically harsh environments
EIA/TIA-232-F / V.28 compliance ensures interoperability with standard RS-232 equipment and legacy serial communication interfaces

What is MAX211CDBG4 used for?

The MAX211CDBG4 is used in embedded systems, industrial controllers, and communication equipment requiring multiple RS-232 serial ports driven from a single 5V supply. It is well-suited for multi-port serial interfaces in modems, routers, PLC systems, and microcontroller-based designs where physical size and component count are constrained. The integrated charge pump makes it ideal for applications where generating bipolar supplies would add complexity and board space.

Frequently Asked Questions

Which RS-232 channel mix does MAX211CDBG4 provide for serial interface boards?

MAX211CDBG4 combines four transmitters and five receivers in a 28-pin SSOP device, making it useful when a board needs multiple EIA/TIA-232-F signal paths.

How does the device simplify single-supply RS-232 level translation?

The transceiver includes an on-chip charge pump for 5 V operation, so designers can implement RS-232 voltage levels without adding a separate negative supply rail.

What lifecycle planning is important when specifying MAX211CDBG4 today?

Because MAX211CDBG4 is listed as obsolete, buyers should validate remaining 28-pin SSOP inventory, approved substitutes, and date-code requirements before committing it to production.
