FAIRCHILD SEMICONDUCTOR? LM555CN? 芯片, 定時器, 單路, 16V, DIP-8
The LM555CN is a highly stable Controller/Single Timer, capable of producing accurate timing pulses. With monostable operation, the time delay is controlled by one external resistor and one capacitor. With a stable operation, the frequency and duty cycle are accurately controlled with two external resistors and one capacitor.
