MAX3380ECUP+

MAX3380ECUP+ is a1µA, 2Tx/2Rx RS-232 transceiver with ±15kV ESD-protected I/O and logic pins. The MAX3380E is +2.35V to +5.5V-powered EIA/TIA-232 and V.28/V.24 communication interfaces with low power requirements, high data-rate capabilities, and enhanced electrostatic discharge (ESD) protection on both the TTL and RS-232 sides. 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 proprietary 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. Suitable for cell phone data lump cables, PDA data lump cables, GPS receivers, digital cameras.

• 2.35V to +5.5V operating range is fully compatible with lithium-ion (Li+) batteries
• Charge pump requires only four small 0.1µF capacitors for operation
• Low logic threshold down to +1.65V for compatibility with cell phone logic supply voltages
• Compatible with next-generation GSM data rates
• 100V/µs max transition region slew rate at VCC = +4.2V, -3.0V < T-OUT< +3.0V,RL = 3kohm
• 30V/µs max transition region slew rate at VCC = +2.35V, -3.0V < T-OUT< +3.0V,RL = 3kohm
• 20 pin TSSOP package
• Operating temperature range from 0 to +70°C
