How to properly use a 74259 (addressable latch)

I am thinking of connecting a 74259 (8-bit addressable latch) to a
USBMOD4 device to ultimately control 8 mosfets. The data *** for the
latch said that you should hold pin G high while changing address lines
to avoid mangling your stored values, and I'm trying to come up with an
elegant solution.

My device sets all 8 data lines "simultaneously"; I need to ensure that
the line connected to the enable doesn't drop until the address/data
lines are set up.

I was thinking of a simple RC circuit sent into an schmitt inverter to
delay the dropping of G for ~100ms...would this work reliably? Are
there better ways of doing this?
