I am trying to get a basic circuit for driving a TTL signal to 50 Ohms. The supply voltage will be 3V to whatever circuitry I use. One idea was to use the SN74128 (Vcc too high) or the LVC1G126. I will end up putting enough in parallel to satisfy the current requirement of approximately 50mA at 2.5V output level.
What is a recommended part for this? I found 49 parts for logic gates that supported a Vcc down to 3V for TTL level logic in/out so was having a hard time narrowing it down.
Thanks,
