TFBS4650 Features
• Compliant with the IrDA physical layer IrPHY 1.4 (low power specification, 9.6 kbit/s to 115.2 kbit/s) • Link distance: 30 cm/20 cm full 15° cone with standard or low power IrDA, respectively. Emission intensity can be set by an external resistor to increase the range for extended low power spec to > 50 cm • Typical transmission distance to standard device: 50 cm • Small package - L 6.8 mm x W 2.8 mm x H 1.6 mm • Low current consumption 75 A idle at 3.6 V • Shutdown current 10 nA typical at 25 °C • Operates from 2.4 V to 3.6 V within specification over full temperature range from - 25 °C to + 85 °C • Split power supply, emitter can be driven by a separate power supply not loading the regulated. U.S. Pat. No. 6,157,476 • Lead (Pb)-free device • Qualified for lead (Pb)-free and Sn/Pb processing (MSL4) • Device in accordance with RoHS 2002/95/EC and WEEE 2002/96/EC
