Overview
Description
The MAX3311EEUB is Maxim/Analog Devices’ RS-232 transceiver (level shifter) in an 8-pin package. It provides a single UART interface and converts TTL/CMOS logic levels to RS-232 voltage levels (and back), using an internal charge pump to generate the required RS-232 voltages from a single supply. It’s typically used to connect a microcontroller or microprocessor to an RS-232 serial port (PCs, modems, serial peripherals). The EEUB suffix denotes the specific RoHS-compliant lead-free package/revision. For exact electrical specs (supply range, data rate, output voltage swing, current consumption) and pinout, consult the official datasheet for MAX3311EEUB.
Equivalent
Equivalents: other 2-channel RS-232 transceivers with 3V–5.5V supply, e.g. Maxim MAX3232/MAX3237; Analog Devices ADM232/ADM232A; TI SP3232 (and SP3234); STMicroelectronics ST232 (SP232). Note: check pinouts and voltage ranges to ensure pin-for-pin compatibility.
