  • RE: NE555: Output behaviour in case of fault + NA555 differences

    Hi Antonio, The only difference between the NE555 and NA555 are the operating temperatures. NA555: -40C to 105C. NE555: 0C to 70C. Otherwise, they are functionally the same. Unfortunately, the output of a broken device is unpredictable. It's possible…

  • NE555: Switching on and off duration at monostable operation

    TI Thinks Resolved
    Part Number: NE555 Hello team, Could you give me comment on if NE555 can be used to switch on and off time at monostable operation like as Figure 10? In my understanding, the on time duration can be decided by C and RL. The customer wants to confirm…

  • RE: NE555: NE555 50% duty application issue

    Resolved
    Zhengxing Li, The output of NE555 uses NPN transistors. For VOL the saturation voltage is close to 0V. The VOH is a base emitter diode drop lower than VCC. Because of this drop the duty cycle won't be 50%. The discharge output transistor is heavily…
