Jon, on the short drive home I realized that a couple of transistors would work just as well as the I/O expander and avoid the time "problem".

Also, those drivers have distinct logic and motor drive power Vin's so you can drive the logic input directly with your MCP23008 or Raspi GPIO. (A word of warning though, using an I/O expander to drive a stepper pulse is going to be pretty slow)
