- High Data Rate: Supports data rates up to 460kbps, ensuring smooth and efficient communication for high-speed data transfers.
- AutoShutdown Plus™: This feature allows the device to automatically enter a low-power shutdown mode when not in use, reducing power consumption and extending battery life.
- ESD Protection: The MAX3318EAP is equipped with ±15kV ESD protection on transmitter outputs and receiver inputs to safeguard against electrostatic discharges.
- Small Package: Available in a 20-pin SSOP package, it is compact and saves valuable board space in space-constrained applications.
- Latch-Up Performance: It exceeds 100mA per JESD 78, Class II, ensuring reliable operation even under stressful conditions.
Applications
The MAX3318EAP is versatile and can be used in a variety of applications, including:
- Battery-Powered Equipment
- Handheld Devices
- Notebook, Subnotebook, and Palmtop Computers
- Peripherals
- PDAs and Organizers
Technical Specifications
The device features a dual charge pump that allows for RS-232 performance from a single power supply ranging from 2.5V to 5.5V. Its receivers remain active during shutdown, which allows devices to monitor data activity. The MAX3318EAP also includes a transmitter output and receiver input that are protected against ±15kV electrostatic discharge (ESD) shocks, without latch-up.
Its compact form factor, low-voltage operation, and enhanced power-saving features make the MAX3318EAP an excellent choice for designers looking to integrate RS-232 communication capabilities into their low-power or portable applications.
