My customer test that Q output is not always Low level when Pin SRCLR set low level. so, that will cause the led signal some times lighting,and some times dim.
we want to know the clearly status of the Q output when the IC started.
thank you!

Hello,
The clear pin only forces the internal registers to zero. The output registers still can have an unknown state at startup as described here: https://e2e.ti.com/support/logic/f/logic-forum/737715/faq-what-is-the-default-output-of-a-latched-device-flip-flop-latch-register
