Are your supplies symmetrical or do you use it single supplied?

+7.5 and -5.5, so we can make anything from TTL to ECL output levels.
But that shou;dn't affect input impedance symmetry.

Not so dummy, when you screw the TTL logic with wrong level you screw your
output as well. What planet are you from?



We speak English here. What planet are you from?

Ah, some wannabee who is too dumb to understand electronics, and
barely smart enough to fake posts.
