Product Overview
MAX3311ECUB+ is a low-power, 5V EIA/TIA- 232-compatible transceiver. All transmitter outputs and receiver inputs are protected to ±15kV using the Human Body Model, making this device ideal for applications where more robust transceivers are required. It has one transmitter and one receiver. The transmitter has a proprietary low-dropout transmitter output stage enabling RS-232-compatible operation from a +5V supply with a single inverting charge pump. This transceiver requires only three 0.1μF capacitors and will run at data rates up to 460kbps while maintaining RS-232-compatible output levels. The MAX3311E features a 1μA shutdown mode. In shutdown the device turns off the charge pump, pulls V- to ground, and the transmitter output is disabled.
- ESD protection for RS-232-compatible I/O pins ±15kV—human body model
- 1μA low-power shutdown
- Receiver active in shutdown
- Single transceiver (1Tx/1Rx) in 10-pin μMAX package
- Temperature range from 0°C to +70°C
