Description

MAX3243EEUI+T is a Maxim RS-232 triple transceiver. It provides three RS-232 drivers and three receivers, so a MCU or microprocessor can talk to three RS-232 devices. It runs from a single 3.0–5.5 V supply and uses an internal charge pump to generate RS-232 voltage levels (roughly ±6 to ±10 V) from the logic supply. On the logic side it connects to TTL/CMOS signals; on the RS-232 side it presents standard RS-232 levels. Features typically include three drivers/three receivers, low quiescent current, and the ability to deactivate unused channels for power saving. The suffix +T usually denotes Tape & Reel packaging; EEUI codes indicate specific grading/packaging options (often extended/industrial temperature variants). For exact temperature range and packaging, check the datasheet. Common applications: microcontroller serial ports, embedded systems, modems, and serial peripherals needing multiple RS-232 ports.

Features

Key features of MAX3243EEUI+T:
- Quad RS-232 transceiver: 4 drivers and 4 receivers
- 3.3V single-supply operation (typical 3.0–3.6V)
- Internal charge pump using four 0.1 µF capacitors to generate RS-232 levels
- RS-232 signaling with standard voltage swings (typical ±6V)
- Compatible with TTL/CMOS UART interfaces
- Extended operating temperature: -40°C to +85°C
- Low quiescent current with optional power-down mode
- ESD protection on RS-232 lines
- Packaging: Tape & Reel (T) for automated assembly
Note: All specs come from the MAX3243 family; verify exact numbers in the datasheet for your variant if needed.

Package

MAX3243EEUI+T comes in an 8‑pin SOIC package (SOIC-8); the “+T” indicates Tape‑and‑Reel packaging.

Pinout

- Pin count: 20 pins (quad package, e.g., TSSOP/SSOP variant, plus Tape-and-Reel option “+T”).
- Function: Quad RS-232 transceiver (four drivers and four receivers) with internal charge-pump level shifter. Converts TTL/CMOS UART signals to RS-232 levels and RS-232 levels back to TTL/CMOS; operates from single supply (typically 3.0–5.5 V).

Manufacturer

- Manufacturer: Maxim Integrated (now part of Analog Devices).
- What kind of company: An American semiconductor company that designs and manufactures analog and mixed-signal integrated circuits (fabless).

Application

Applications of MAX3243EEUI+T:
- 4-channel RS-232 transceiver for embedded systems with 3.3V logic
- Industrial automation and telemetry equipment
- Point-of-sale devices (POS terminals, printers, modems)
- Instrumentation, test and measurement gear, data loggers
- Networking equipment console ports and other RS-232 interfaces
Notes: Provides RS-232 level shifting with integrated charge pumps, suitable for space- and power-constrained designs.
