#184573 - "its input is kept floating" do you mean Responding to: ???'s previous message |
I tested on 74LS245, its out is at logic "1" when its input is kept floating .... if input is floating output should be at high impedance.
Suggest me any other solution of this problem if possible. "its input is kept floating" do you mean OE pin activated? any chip with floating output will on its output pin reflect the envoronment i.e. if the path in the circuit (other chips connected, ...) has a lower impedance to high it will go high if the path in the circuit has a lower impedance to low it will go low Erik |
