Thank you for the suggestions! I remember finding the 4504 but did not have one in my parts kits to try and forgot about it, it looks very promising. I have over 60 circuits to buffer so the hi-speed MD1810 would be more then I could afford and requires outboard inverse drivers. I really...

Which brings me to the OP, I need a solution that is in one chip, If I convert and buffer again it's two chips + glue. Thankx again, Jmayes

Some of the circuits end up going around several boards after the entry point so I really just need a good tight 12V signal that can withstand probably 6 feet of wire. This is a retrofit to a 80's model device so most of the signals go to plain transistors and diodes. It is a MUX buss type of...

Yes, using a proper scope probe :) and Yes, I am driving a length of cable (about 3 feet), using standard ribbon with every other conductor grounded. So yes the capacitance is what is killing me so hence the need for a stronger active pull-up and pull-down. Sorry I did not think to add that...

In fact I tried that exact combination of 7407 & pull-up, I had to go down to 330 ohms and the edge was only just fair, I could use it but it was not ideal and power consumption was high (most of the time the signal is at Gnd level). I know the UDN part is a high current driver with no...

Hi, new to these forums and glad I found them! I am working on a project that requires conversion of fairly hi-speed signals (10us pulses) from 5V to 12V. The usual open collector with a pull up is much too slow getting from 0 to 12V. I really need the ramp to happen between .05us to 1us...
