It has five flash outputs with 10mA drive capability that can implement random or sequence flashing function controlled by one option pin. It only requires one external resistor for typical application. It is very suitable for the use of the flash products such as disco glasses, disco hat, gift card, X’mas decoration and so forth. B. Features — • C-MOS Metal-Gate Process. • Operating voltage: 1.2V ~ 4.5V. • Low stand-by current: 1µA at 3V. • Five lamp flash driver with 10mA driving capability. • Random or sequence flash selection • toggle on/off control function. • 1/10 duty cycle output. • Built-in oscillator. • Minimum external components.
