KK1503 circuit equivalent, cmos lsi leds driver circuit.
* Single 3V battery operation
* Low stand-by current
* No external R-C component required for oscillation
* Direct drive LEDs (open-drain output)
FUNCTIO.
The KK1503 is a CMOS LSI LEDs driver circuit. An automatic cut off function is built in to lower the current consumption. The metal mask can be modified in order to adjust the flashing rate, the duty cycle and the time of flash to a particular value..
