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.
