NA556: NA556

Part Number: NA556

Hi TI Team,

We are using NA556 in one of our product for Astable & Monostable functions. I am giving the voltage of 1.26V to NA556 RESET pins. According to the data sheet the voltage range for RESET pin is 0.3V to 1.0V. What is the impact on performance of NA556 if I give the voltage of 1.26V to RESET pins. Does this over voltage causes malfunction/performance degradation of NA556? Revert back with the anticipated failures due to this variation in RESET voltage.

Regards,

Raja Sekhar

    Raja,

    When RESET pin is 1.26V then reset function will be off (inactive). The output will by controlled by trigger and threshold pins.

    The 0.3V to 1V range in the data sheet means;
    For reset < 0.3V, output is reset to low and stays low.
    For reset > 1V, output is controlled by trigger and threshold
    For 0.3V<reset <1V, the device could be reset or it might not be reset. Do not use this voltage range.

    The reset voltage parameter is the voltage where the reset changes state. It is a device parameter, not an application range.
    Reset can be any voltage between 0V and VCC. however 0.3V to 1V is not recommended.
