timing signal generators, such as monostable and astable multivibrators. It has trigger, threshold, and control pins.
Inputting a signal to the reset pin can stop the circuit operation easily. In addition, the output can sink current as high
as 200 mA (maximum). So, it can be used to drive relays and lamps.
TYPICAL CHARACTERISTICS
• Supply voltage
• Circuit current (V
• Output current capacity
• Temperature stability
• Rising and falling time
