Hi,
Thanks all. So, there is two different configuration in the output stage of each channel, 4---push-pull configuration and 2 transmission gate. I need to implement the output stage in discrete since the IC is no longer in production.For the push-pull configuration, I have found a solution like L2293Q which feature 4--push-pull channel...I am yet to find a solution to the transmission gate. In our case, we need a total of 128 transmission gates for 64-output channels.
Q1: Is there any solution which offers the 128 transmission gate in a single package and it has an option to control from push-pull stage's output as in the attached diagram?.
Q2: The solution we had for the push-pull configuration is having only 4-channels .Hence, the application will need 64-chips of L2293Q for 64-output channels which in turn increase the board size. So, I appreciate if anyone suggests a greater number of channels with the same output current as in the L2293Q.
Thanks,
Muthu
