I am using a raspberry pi 4b. I am attepting to send a signal to a motor controller that requires a 5v input. Is that possible with the pi or will i need to purchase a part. If so please advise an recommendations. The part is DM8078 made by microkinetics

The data sheet lies! It claims to need TTL input @30mA. It also claims to be open collector compatible. No TTL source is capable of this. Real TTL is current driven, capable of sinking current but only sourcing limited current.
I suspect it actually has opto-isolators as input.
These can be driven with a simple transistor circuit (but you would need to conform this). See https://raspberrypi.stackexchange.com/a/118117/8697 for examples.
