who makes the 74lvt541
Hi
I have a problem in design a digital system.
I have a circuit that have 8 (TTL-74hc541) digital outpus(DO1~DO8).
I have to use two of these circuit in a system and connect the similar digital outputs together.(ex. DO1 of one
circuit is connected to DO1 of another one ,and so on).The digital outputs are inputs of another card.
at the same time only one of two circuit can be powered on ,the other one must be powered off.
Is this connection makes problem for the off circuit ?
(digital outputs are 74HC541)
or simply I say, can I connect outputs of two 74HC541 together and in state that on of them is powered off,is this make problem
for another 74hc541??
How can I make a better circuit with no risk of failure and design error??
Is open collector design a better choice?
Please give your comments.
