I have an application driving a solenoid with a MOSFET H bridge.
A 5v supply would be enough to drive the bridge and the power is moderate so I could probably build the bridge with logic level complimentary MOSFETS.
The drive will be PWM at around 20 or 30kHz so the MOSFETS need to switch fast and I need to drive them hard.
Anyone have suggestions for a 5v buffer to drive the gates? Preferably cheap and 4 in a package. I was thinking some HC logic bus driver might be up to the job.
Microchip makes the TC4423, TC4424, and TC4425 low-side gate drivers, they have high side as well.

I would recommend using VNH3SP30. I know you mentioned you are looking for _just_ drivers but I have used this part to reduce valuable board real estate.
How much current do you need to control?

Interesting chip (or actually 3 chips in one package) but it is very much targeted towards driving motors. It isn't specified operating below 9v so it isn't a solution for me.
The Microchip range looks promising. They have a quad lowside driver. Thanks for the suggestion.
