a single port for 3 diff purpose
sir,
i'm using 74ls373 latches seperate for each i.e for lcd ,for 8 switches and for another 8 swithes i've connected chip select pins of each latch to port0.5,0.6,0.7 and when i'm using lcd i kept other 2 latch disable by giving low on chip enable pins and for other two also i'm doing same but problem is that when i connect all 3 latches it doesnts give the results in datasheet of 74ls373 it is given that to disable perticulr latch we have to keep
OE pin low but i dont have any port pin to connect these OE pins all port pins are already used what should i do
thank you
