For the ALS logic circuit, estimate:
(a) the current IOL
(b) the delay in a 1-to-0 transition at one of the inputs of GATE 1
appearing as an effect at the output of GATE 5.
(c) the total power consumed by the circuit in a quiescent state.
The Attempt at a Solution
I think this a NAND gate logic circuit, in red I have added the inputs and outputs. I have cropped part of a table, that showed typical values of certain logic families, to show the spec of an ALS. I think im right in saying that this can only be an 74ALS. For (a) the low level output according to the table is 4mA, The low level inputs for gates 2,3 and 4 are 100uA each.
I dont know how or where to find the formulas to solve and my notes are dire.
