MAX3088EESA

The MAX3088EESA is a Maxim/Analog Devices RS-232 transceiver. It provides a bridge between a microcontroller’s TTL/CMOS logic and RS-232 serial ports, handling both the driving of RS-232 outputs and the reception of RS-232 inputs. The device uses an on‑chip charge pump to generate the required RS-232 voltage levels from a single supply and includes standard protections suitable for embedded systems.
Key points:
- Single-supply operation (typical 3–5.5 V) for easy interfacing to microcontrollers.
- RS-232 level translation with integrated driver/receiver functionality.
- On‑chip charge pump to generate RS-232 swing; supports standard RS-232 signaling.
- Industrial/extended-temperature option (EESA suffix) in a specified package, with lead-free options.
- Suitable for embedded serial interfaces in modems, microcontroller projects, and telecom equipment.
For exact electrical specs (data rate, voltage levels, quiescent current, pinout, package details), refer to the MAX3088EESA datasheet.
