Description
MAX3094EEUE is Maxim Integrated’s MAX3094 RS-232 transceiver family (package suffix EEUE indicates the specific packaging/temperature grade). It provides multiple RS-232 transmitters and receivers (typically a quad channel device) that convert between TTL/CMOS logic levels used by microcontrollers and the RS-232 voltage levels used on serial lines. Key points:
- On-chip charge pump to generate RS-232 voltage swings from a single supply (3.3V or 5V systems).
- Bidirectional transceiver channels, with TTL/CMOS-compatible inputs and 3-state outputs.
- Built-in protections (ESD/overvoltage) and relatively low power consumption.
- Suitable for microcontroller-to-serial-port interfaces in embedded systems, modems, POS, etc.
For exact channel count, supply ranges, data rates, pinout, and package details, consult the MAX3094EEUE datasheet and product page.

Features
Here are the typical features of the MAX3094EEUE RS-485/RS-422 transceiver:
- Single-supply operation (5V)
- RS-485/RS-422 compatible two-wire transceiver
- One driver and one receiver
- DI (driver input), RO (receiver output), and DE/RE control pins
- 3-state outputs for easy bus sharing
- Fail-safe receiver output (RO goes high when the bus is idle/open/shorted)
- Wide receiver input/common-mode range suitable for RS-485 networks
- Fast propagation/slew rate suitable for moderate to high data rates
- Low quiescent current (power-saving modes)
- ESD protection on bus pins (typical for rugged bus operation)
Note: Exact specifications (data rate, current, voltage ranges, etc.) vary by package and revision. Please consult the latest datasheet for precise numbers.
