With a monostable operation, the time delay is controlled by one external resistor and one capacitor. With an astable operation, the frequency and duty cycle are accurately controlled by two external resistors and one capacitor. 8-DIP 8-DIP 8-DIP 8-DIP 8-SOP 8-SOP 8-SOP 8-SOP 1 1 Internal Block Diagram Internal Block Diagram Internal Block Diagram Internal Block Diagram F/F F/F F/F F/F OutPut OutPut OutPut OutPut Stage Stage Stage Stage 1 1 1 1 7 7 7 7 5 5 5 5 2 2 2 2 3 3 3 3 4 4 4 4 6 6 6 6 8 8 8 8 R R R RR R R RR R R R Comp.
