Key Features
- 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
Applications
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
How many transmitters and receivers does the MAX211CDBG4 provide?
The MAX211CDBG4 provides four RS-232 transmitters and five RS-232 receivers in a single 28-pin SSOP package, allowing implementation of multiple serial channels without additional level-translation components, saving board space and bill-of-materials cost.
Does the MAX211CDBG4 require a bipolar power supply?
No, the MAX211CDBG4 operates from a single 5V supply and uses an integrated charge pump to generate the ±10V voltage levels required by the RS-232 standard (EIA/TIA-232-F), eliminating the need for an external bipolar or negative supply rail.
What interface standard does the MAX211CDBG4 support?
The MAX211CDBG4 is compliant with EIA-232-F, TIA-232-F, and CCITT V.28 standards, ensuring full compatibility with RS-232 serial communication equipment including modems, terminal devices, industrial controllers, and legacy serial peripherals.
What is the significance of Schmitt trigger inputs on the MAX211CDBG4 receivers?
Schmitt trigger inputs on the MAX211CDBG4 provide input hysteresis, which improves noise immunity by preventing false triggering on slow-slewing or noisy RS-232 input signals. The maximum high-level input current of 200µA ensures safe loading of upstream RS-232 drivers.
