Using Hex Inverters to generate 0, -5V output

Hi there, I was wondering if anyone can help me design a simple circuit
to drive a switch. The switch has two states, and expects two inputs.
To put the switch in state one, it needs inputs 0V, -5V and to put it
in state two, it's inputs need to be -5V, 0V. So what I'd like to
design is a driver that takes a 0 / +5V signal, and converts it to the
appropriate output state.
Truth Table:
Input Output 1 Output 2
0V 0V -5V
+5V -5V 0V
Now, I thought I could use a hex inverter in a kind-of negative state
(i.e. Vcc = GND, GND = -5V) to generate the appropriate negative
voltage, but playing around in the lab hasn't been so helpful. Can
anyone suggest a way that I can do this? Switching times aren't
important.
Thanks!
