Maxim Integrated MAX3318EEUP Overview

The MAX3318EEUP from Maxim Integrated is a high-performance, 2.5V, 460kbps, RS-232 Transceiver with AutoShutdown Plus™. Designed to operate at low voltages, this device is suitable for battery-powered applications such as laptops, PDAs, and other portable devices where power conservation is critical.

Key Features

• Low Voltage Operation: The device is designed to operate at a supply voltage range of 2.25V to 2.75V, making it ideal for low-power applications.
• High Data Rate: With a data rate of up to 460kbps, the MAX3318EEUP is capable of supporting high-speed communication requirements.
• AutoShutdown Plus™: This feature significantly reduces power consumption by entering a low-power shutdown mode when the RS-232 cable is disconnected, or the transmitters of the connected peripherals are off.
• ESD Protection: The transceiver includes ±15kV ESD protection on transmitter outputs and receiver inputs, which helps to prevent damage from electrostatic discharges.
• Small Package: Available in a 20-pin TSSOP package, the MAX3318EEUP is designed to save space on PCB layouts.
• Dual Charge Pump: The integrated dual charge pump circuitry generates the necessary RS-232 voltage levels (±5.5V) from a single low-voltage supply.

Applications

• Portable and Battery-Powered Equipment
• Notebook, Subnotebook, and Palmtop Computers
• Handheld Equipment
• Peripherals

The MAX3318EEUP provides designers with a compact, efficient, and reliable solution for RS-232 communications in portable devices. Its AutoShutdown Plus™ feature, combined with low operational voltage and high ESD protection, ensures that the device can manage power and protection requirements in challenging environments. The high data rate and small package size make this transceiver an excellent choice for modern, high-speed, space-constrained applications.
