It features the smallest footprint in the industry at 2.5 H x 8.0 W x 3.0 D mm. Although the supply voltage can range from 2.7 V to 3.6 V, the LED drive current is internally compensated to a constant 32 mA to assure that link distances meet the IrDA Data 1.4 (low power) physical I/O Pins Configuration Table layer specifications.
