MAX3120CSA+T

19-1390; Rev 0; 10/98 Low-Profile, 3V, 120µA, IrDA Infrared Transceiver The MAX3120 IrDA 1.2-compatible infrared transceiver is optimized for battery-powered, space-constrained applications. It consumes only 120µA while supporting data rates up to 115kbps over a wide 3V to 5.5V operating range, and features a 10nA shutdown mode to further extend battery life. The MAX3120 reduces the space required for IrDA applications by requiring a minimum of external components: photodiode, infrared LED, and current-setting resistor. Optical components are external to allow maximum flexibility in PC board design. The MAX3120 is available in 8-pin µMAX and SO packages. The µMAX package consumes half the board space of an 8-pin SO.
