SN74LV74A: Continuous output current in case of short time rating(10ms～50ms)

Part Number: SN74LV74A
Other Parts Discussed in Thread: SN74LVC1G34

Hi all

Would you mind if we ask SN74LV74A?

How much is output current in case of short time rating(10ms～50ms)?
The datasheet shows continuous output current with /sec level.
If you have these data, could you let us know?

Kind regards,

Hirotaka Matsumoto

    Hello Matsumoto-san,
    There is no time limit on the 25mA absolute maximum rating -- whether it is 1ns or 1s, it still violates the datasheet spec to go above 25mA.

    This device is really designed to drive 12mA, not 25mA. If you need more current, I would recommend adding a driver after the output such as the SN74LVC1G34 (or similar).
