ABSOLUTE MAXIMUM RATINGS

These are stress ratings only and functional operation of the device at these ratings or any other above those indicated in the

operation sections of the specifications below is not implied. Exposure to absolute maximum rating conditions for extended periods

of time may affect reliability.

ELECTRICAL SPECIFICATIONS

Specifications are at TA=25°C, VIN = 3.3 to 5.5, ENABLE =VIN, ♦ denotes the specifications which apply

over the full operating temperature range, unless otherwise specified.

Note 1: Output current Multiplication Ratio (ILED/ISET) is not linear. For actual ratio and ILED please refer to typical

performance characteristics on pages 4 through 7.

Note 2: ENABLE "ON" is VON/OFF where ILED1 > 20mA @ VLED1 = 0.3V.

ENABLE "OFF" is V where I < 1µA @ V > 0.3V.
