Description
MAX3094ECSE is a Maxim Integrated RS-232 transceiver IC (typically a quad/channel device) designed to connect microcontroller UARTs to RS-232 serial links. It provides TTL/CMOS logic interfaces on one side and RS-232 voltage levels on the other, enabling multiple independent serial ports from a single MCU.
Key points:
- On-chip charge pump generates RS-232 voltages from a single 3.0–5.5 V supply, avoiding external supplies for RS-232 levels.
- Four drivers and four receivers (multiport capability) for multiple UARTs.
- Includes protection features and is suitable for embedded, industrial, and networking applications requiring multiple RS-232 links.
- ECSE in the part number denotes the specific package/temperature grade.
For exact specs (pinout, data rates, supply ranges, capacitance, and protection details), refer to the MAX3094ECSE datasheet. If you need only one-channel RS-232 or different package options, consider related parts in the MAX309x family.

Features
Here are typical features of the MAX3094ECSE RS-485/RS-422 transceiver:
- Quad RS-485/RS-422 transceiver (two drivers, two receivers)
- Single-supply operation (3.3V–5V)
- High-speed data-rate capability (per-channel, suitable for industrial buses)
- Separate driver-enable (DE) and receiver-enable (RE) with tri-state outputs
- Fail-safe receivers (guaranteed logic-high output with open/shorted/idle inputs)
- Differential signaling with wide bus fault and common-mode tolerance
- Robust ESD and fault protection on bus pins
- Low quiescent current for multi-drop/multi-node networks
Optional: packaging and exact electrical specs vary by revision; consult the current datasheet for pinout, exact voltage ranges, and performance numbers.
