#184572 - Goal Responding to: ???'s previous message |
Hi,
Thanks for replies. I want to drive four Common Anode 7-segment display. I tested on 74LS245, its out is at logic "1" when its input is kept floating or not connected to "1" or "0", so all the segment of display always on. So I am looking for such buffer IC whose output strictly follows the input. I mean when input is 1 or 0 then only output is 1 or 0 and if input is floating output should be at high impedance. Suggest me any other solution of this problem if possible. Bye |
