You need an inverted output, /Q. Only the SN74LVC1G80 has /Q.

Hi Clemens,

I saw SN74LVC1G80 datasheet and find right application at 9.1.

When customer doesn't connect MCU GPIO, what happens on initialization?

Regards,

Hayashi

Hi Hayashi,

Initialization from a microcontroller is not necessary, however the flip flop will start up in an undermined state either outputting high or low. This is a property of flip flops and latches.

Please see this FAQ for more information on this.
