MAX3319EEAE+

The MAX3319EEAE+ is a ±15kV ESD protected, 460Kbps RS232 compatible transceiver with AutoShutdown Plus in 16 pin SSOP package. The IC's transmitter is an inverting level translator converts CMOS logic levels to RS232 compatible voltage levels. It gives a 460Kbps data rate with worst case loads of 3Kohm in parallel with 1000pF, providing compatibility with PC to PC communication software (such as LapLink). Receiver convert ±3.7V to ±13.2V RS-232 signal levels into CMOS logic output levels. The transceiver have a proprietary low-dropout transmitter output stage enabling RS232 compatible operation from a +2.25V to +3V supply with a dual charge pump and charge pump requires only four 0.1µF capacitors. Devices automatically enter a low-power shutdown mode when the RS-232 cable is disconnected or the transmitters of the connected peripherals are inactive for more than 30 seconds. They turn on again when they sense a valid transition at any transmitter or receiver input.

• Supply voltage range is 2.25V to 3V
• Operating temperature range from -40°C to 85°C
• Minimum transition-region slew rate is 4V/µs
• Transmitter skew rate is 100ns & receiver skew rate is 50ns
