Description
MAX333AEUP is a Maxim RS-232 transceiver that provides a TTL/CMOS-to-RS-232 interface. It includes an internal charge pump that generates the required RS-232 voltage levels from a single supply, so it can run on a small 3–5V supply and connect directly to RS-232 devices. It translates logic-level inputs to RS-232 outputs and RS-232 inputs to logic-level outputs, enabling full-duplex serial communication with minimal external components—typically just charges-pump capacitors. The device is intended for compact, low-power embedded systems needing a simple RS-232 interface. For exact data rates, voltage levels, timing, and pinout, consult the MAX333AEUP datasheet.

Features
Here are the typical features of the MAX333AEUP:
- 3-channel RS-232 transmitter/receiver (three drivers and three receivers)
- Single-supply operation from 3.0 V to 5.5 V
- On-board RS-232 level shifters with voltage-generation (charge-pump) from the supply
- TTL/CMOS logic-level inputs and RS-232-compatible outputs
- Three-state outputs for bus sharing and multi-device daisy-chaining
- Low-power operation with optional shutdown
- ESD/over-voltage protection on I/O lines
- Designed for standard RS-232 signaling (EIA/TIA-232-F)
Note: For exact electrical specs (data rate, cap requirements, I/O timing, and package options), refer to the MAX333AEUP datasheet.
