hi i need help

a question on an assignment to be more specific

who is willing?

well here goes

a TTL gate has to sink 0.6mA for each driven gate. if I(ol)max is 13mA what is the fan out figure for this TTL family

i have 2 seperate answers someone said 10 which doesnt sound right but i found something else which said ip/op which i think is 13mA/0.6mA

look up the fan out in the reference literature for the device - 10 is just a useful - when in doubt figure
