Product specification: Universal system timer NE555 - TNT

    • Supply voltage: 4.5 to 16 Volts
    • The maximum power dissipation of 600 MW
    • Maximum output current 100 mA
    • Current at 5 V supply: 3mA
    • Current at supply voltage of 15V: 10mA


    Details in the documentation.


    The pins of the chip NE555:


    1. GND - mass system

    2. TRIGGER - trigger Input. When the entrance was set a voltage below 1/3 of the supply voltage, the unlocking of the system, and the output appears a high status.

    3. OUT - Output system

    4. The RESET - Input low resets the system. The output is set to high, the external capacitor will be discharged.

    5. CONTROL area is designed to change the proportions of the internal voltage divider.

    6. The THRESHOLD input of the comparator are disconnected from the network, the internal trigger. When this input voltage will be higher than 2/3 of the supply voltage, the IC output set to low status.

    7. DISCHARGE output used to discharge an external capacitor. This is the conclusion of the collector of the internal transistor.

    8. VCC - the power of the chip.

    1. Comparator disable the trigger

    2. Comparator-enable the trigger

    3. Brave rezystorowy (R=5kOm)

    4. Trigger

    5. Transistor rozładowujący.


    Rezystorowy divider sets the threshold voltage for Comparators respectively 1/3 (1) 2/3 (2) supply voltage.







    The range of the system also in the case of SMD , as well as stand.
