Other Parts Discussed in Thread: SN74LVC1G74

There is a TG block used in the block diagram for the SN74LVC1G74.

Can you please explain what this TG block is and how it works in the circuit.

Thanks for your help with this!

"TG" stands for "transmission gate"; it allows the signal to pass through only when the clock is high/low.

Clemons,

Thanks for your response.

I just had not seen this type representation in any of our other logic devices and thus the confusion.

Thanks for your help!
