MAX232DR Typical application Circuitry

MAX232DR

The MAX232DR is a part of the MAX232 series produced by Maxim Integrated. This series is comprised of integrated circuits designed to function as dual driver/receivers, enabling RS-232 communication by converting TTL/CMOS logic levels to RS-232 voltage levels and back. This makes the MAX232 series essential for serial communication applications where interfacing between microcontrollers or digital systems and RS-232 compliant devices, like modems and printers, is required.

1. T1IN (Pin 11) and T2IN (Pin 10): These pins serve as the TTL/CMOS logic level inputs. They should be connected to the TTL/CMOS signals from your system that need conversion to RS-232 levels.

2. R1OUT (Pin 12) and R2OUT (Pin 9): The RS-232 level output pins, R1OUT and R2OUT, provide the converted signals from TTL/CMOS inputs and should be connected to your RS-232 interface.

3. T1OUT (Pin 14) and T2OUT (Pin 7): These are the RS-232 level output pins, converting signals from RS-232 inputs to TTL/CMOS levels. Connect these to the TTL/CMOS receiving devices.

4. R1IN (Pin 13) and R2IN (Pin 8): The input pins for RS-232 signals, R1IN and R2IN receive signals from an RS-232 source to be converted into TTL/CMOS levels.

5. VCC (Pin 16): Connect this pin to a +5V supply voltage.

6. GND (Pin 15): The ground pin, which needs to be attached to the ground of the system.

7. External Capacitor Connections (C1+, C1-, C2+, C2- on Pins 6, 5, 4, 3): These pins are designated for connecting external capacitors. These capacitors are a component of the charge pump that creates the voltage levels required by RS-232.

8. Voltage Outputs (V+ on Pin 2 and V- on Pin 1): These pins output the positive and negative voltages from the charge pump, used for RS-232 level conversion.

For a thorough understanding of the MAX232DR, including pin configurations and electrical characteristics, the datasheet should be consulted. It offers comprehensive information and guidelines for effective integration of the MAX232DR into serial communication interfaces.

When designing circuits with the MAX232DR, it's important to correctly set up the TTL/CMOS inputs (T1IN, T2IN), RS-232 outputs (T1OUT, T2OUT), and RS-232 inputs (R1IN, R2IN). Also, establishing the power supply (VCC), grounding (GND), and arranging the external capacitors for the charge pump (C1+, C1-, C2+, C2-) are critical for ensuring the successful operation of the device in RS-232 communication systems.
