Key Features

• Integrated Interface: The MAX238ENG+ includes five drivers and three receivers, making it capable of supporting a full-duplex RS-232 communication link.
• Electrostatic Discharge (ESD) Protection: Each transmitter and receiver is protected against ±15kV ESD shocks, ensuring the device's resilience in harsh environments.
• Low Power Consumption: The device operates with a low supply current, typically 8mA, making it suitable for power-sensitive applications.
• Wide Supply Voltage Range: It is designed to operate from a single +5V supply, with the capability to handle ±5V to ±15V input levels.
• On-Chip Charge Pump: The integrated charge pump circuitry generates the necessary RS-232 voltage levels (+/-10V) from a single 5V supply, eliminating the need for additional power supplies.
• Flexible Data Rate: The MAX238ENG+ supports data rates up to 120kbps, accommodating a wide range of communication speeds.
• Shutdown Mode: A shutdown mode reduces power consumption by placing the transmitters in a low-power state.
