MAX33251EELC+

MAX33251EELC+ is a 600V isolated, RS-232 transceiver with ±15kV ESD and integrated capacitors. The isolation barrier protects the logic UART side from electrical transient strikes from the field side. It also breaks ground loops and large differences in ground potentials between the two sides that can potentially corrupt the receiving and sending of data. The isolated RS-232 transceiver has integrated charge pump and an inverter to eliminate the need for a high positive and negative voltage supply. Also have integrated charge pump and inverter capacitors to help further reduce PCB space. The supply pin VCCA on the UART logic side operates from a dual voltage supply from +3V to +5.5V. VCCB also operates from +3V to +5.5V, simplifying power requirements and enabling level translation between the two voltages. Suitable for diagnostics equipment, POS systems, industrial equipment, GPS equipment, communication systems, medical equipment.
