I have a square pulse that I need to convert into a stable high. Preferably I would like it to be high until I send another pulse to reset. Is there a single IC that will do this?

It is called a set-reset (S-R) flip flop. The 7473 (or 74LS73, 74HCT73, etc) is a J-K flip flop that can be wired as a S-R flip flop.
Alternatively you can take 2 NAND gates (7400, 74LS00, etc. -- in which there are 4 NAND gates inside a single integrated circuit), and take the outputs of each (of 2) NAND gates and wire them to the inputs of the opposite NAND gate. A 0 to 5 volt pulse on one input will set the outputs to one state, while a 0 to 5 volt pulse on the other input will reset the outputs to the original state.

A flip-flop or a monostable multivibrator would probably do the trick.
Even a 555 configured to be a monostable multivibrator might help you and it's dirt cheap.

That's what a J-K Flip-Flop does. Try an internet search on "J-K Flip-Flop" for specs and circuit ideas.

555 IC when configured as Bi-Stable multi- Vibrator .
