MAX3380EEUP+

MAX3380EEUP+ is a +2.35V to +5.5V-powered EIA/TIA-232 and V.28/V.24 communication interface with low power requirements, high data-rate capabilities, and enhanced electrostatic discharge(ESD) protection on both the TTL and RS-232 sides. It has two receivers and two transmitters. All RS-232 inputs, outputs, and logic input pins are protected to ±15kV using IEC 1000-4-2 AirGap discharge method and the Human Body Model, and ±8kV using IEC 1000-4-2 Contact Discharge method. The low-dropout transmitter output stage enables true RS-232 performance from a +3.1V to +5.5V supply with a dual charge pump. The part reduces the transmitter output levels to RS-232-compatible levels with no increase in supply current for supplies less than +3.1V and greater than +2.35V. The +2.35V to +5.5V operating range is fully compatible with lithium-ion batteries. The charge pump requires only four small 0.1µF capacitors for operation. AutoShutdown Plus™ feature to automatically enter a 1µA shutdown mode.

• Operates over entire Li+ battery range
• Low logic threshold down to +1.65V for compatibility with cell phone logic supply voltages
• Compatible with next-generation GSM data rates
• Capable of transmitting data at rates of 460kbps while maintaining RS-232 output levels
• Unique VL pin that allows interoperation in mixed-logic voltage systems down to +1.65V
• Temperature range from -40°C to +85°C
• Available in 20 pin TSSOP package
