MAX3311CUB+ Datasheet PDF - Maxim Integrated

The MAX3311CUB+ is a 460kbps, 1µA supply current, RS232 compatible transceiver in 10 pin µMAX package. This transceiver has a proprietary low dropout transmitter output stage enabling RS232 compatible operation from a +5V supply with a single inverting charge pump. The transmitter is an inverting level translator that converts CMOS logic levels to EIA/TIA-232 compatible levels and receiver converts RS-232 signals to CMOS logic output levels. The inverting charge pump provides a negative voltage from single +5V supply, it operates in a discontinuous mode and requires a flying capacitor and a reservoir capacitor to generate V- supply. It features a 1µA shutdown mode and device turns off the charge pump, pulls V- to ground and the transmitter output is disabled.
