The Y997A is designed as one kind of special flash integrated circuit that uses the standard 8-pin dual-row DIP plastic package. The parameters are as shown: the static current is lower than 5mA, the power supply voltage is 1.8-7V. When the voltage of the output port is 3V, the output current is 15mA, when the voltage is 5V, the output current is 50mA. The breakdown voltage of the output port MOSFET is higher than 18V. The pin functions of the Y997A are as shown: the VDD power supply of pin-8 is positive. The Vss power supply of pin-1 is negative. The pin-7 dsc is the oscillation input port, you can change the flash frequency by changing the values of the external resistance containers. The pin-2 to pin-6 are q1-q5, they are the flash output port; Y997A is the chasing type circulation color light control IC, the flash sequence is q1→q2→q3→q4→q5→q1→q2....
